## Identity
- **Name:** Bending Fork — also **hardy fork**, **turning fork** / **turning hardy** in current retail/maker usage, and, in an older, dated, named-source term, the **hickey** (see below). Wikipedia's own "Hardy tool" article uses a different term again, "**bending drift**," for the same functional category — a genuine encyclopedia-vs-trade-usage naming gap, stated plainly rather than silently harmonized.
- **Family/category:** A **hardy (bottom) tool** — the family this corpus's own [[Anvil]] entry names directly: "cutters, bending forks, bottom swages." The third and last previously-unbuilt member of the Build Queue's original "Hardy Tools" Parking Lot suggestion, after [[Hardy (Hot) Cut]] (cutting side, Run 457) and [[Bottom Swage]] (forming side, Run 458). **A real mechanical distinction from both siblings, worth stating up front:** the bending fork has no struck top-tool counterpart. Its working partner — the bending wrench — is a second hand-leverage tool, not a hammer-struck die, which changes the shape of this entry's Lineage and Matching blocks relative to its two hardy-tool siblings.
- **One-line:** A hardy-shanked (or vise-clamped) tool with two fixed tines spaced to the stock being worked, against which a smith bends, scrolls, or hooks hot bar or round stock by hand, by hammer, or with a paired bending wrench — giving one smith solo leverage and more repeatable curve control than freehand work over the anvil horn.
- **"Hickey" — a real, dated, named-source term, but for the paired tool, not this one.** A direct I Forge Iron post citing Turley Forge (Frank Turley's school — already this corpus's most-cited named voice, via the sibling [[Hardy (Hot) Cut]] and [[Post Vise (Blacksmith's Leg Vise)]] entries) states: "the hickey [is an] old fashioned name for the bending wrench" — not the fork itself. The same post gives the correct-use principle for the pair directly: "It's best to use the two tools together, thus the bend can only come between the near fork post and the far wrench post." [I Forge Iron, "Bending Fork / Scroll Tool dimensions?"]
- **The bending wrench / scroll wrench — a genuine, working partner, not a synonym, though usage blurs the line — now has its own entry: [[Bending Wrench (Hickey)]] (Run 510).** General retail and forum usage often treats "bending fork" and "bending wrench" as loosely interchangeable, but at least one current maker draws the distinction cleanly at the catalog level: a **Hardy Bending Fork** (one slot, hardy-shanked, anchored to the anvil or a vise) versus a **Handheld Bending Fork** (multiple slot widths, a handle instead of a hardy shank, worked off-anvil "for forming and adjusting scroll work and hooks"). [FieryFurnaceForge, product text, directly fetched] Stated here as a live, unresolved ambiguity rather than forced to a false resolution — the same discipline this corpus's sibling entries apply to their own genuinely unsettled naming questions.
- **"Bick iron" — checked directly, a genuinely different tool, not a naming variant worth preserving.** A named tool-collector source (Ivan Raupp and John Czekaj, *Toolshed* journal, CRAFTS of New Jersey, March 2013) describes hand-forged bick irons as a category of **stake anvils** — small, driven into a stump, with a beak/horn form used the way an anvil horn is used for bending — "likely to be very old (17th–19th century or before)." This is a structurally distinct tool (a stake-mounted mini-anvil, not a hardy-shanked fork) with a loosely overlapping *function*, not an alternate name for the same object; no source found this run treats the two terms as synonyms.
- **Why this entry exists.** Run 458 closed the "bottom swage" side of the Build Queue's original three-way "Hardy Tools" Parking Lot suggestion (cutters, bending forks, bottom swages — all three named directly by [[Anvil]]) and explicitly left the bending fork as the sole unbuilt member. This run closes the category. Citation strength at the time of picking: three substantive staged sibling entries ([[Anvil]], [[Hardy (Hot) Cut]], [[Bottom Swage]]) now name it directly, the strongest citation count of any candidate checked this run.

## How NOT to use it (the heaviest section)

**Not-for:**
- **Corrected per the review: cold bending is not a categorical not-for.** The earlier draft claimed every source frames the tool for hot stock only and that no source documents cold use; that claim was false. One current maker does recommend hot steel for its product ("Recommended for use on Hot Steel" [FieryFurnaceForge, directly fetched]) — that is model-specific guidance, not a universal rule. Roland R. Fraser and Earl L. Bedell's 1962 vocational text (*General Metal: Principles, Procedures, and Projects*) discusses bending forks in ornamental ironwork in a context that expressly distinguishes cold bending, and a named practitioner account (Anna Lugthart, "Wafer Iron") documents cold-bending 1/4" rod with bending forks. The actual decision rule: hot work greatly reduces the force needed and is required wherever a maker or process specifies it; cold bending may be appropriate for sufficiently ductile, light-section stock with a fork, mounting, and leverage sized for the load. Do not exceed a maker's rated use or improvise leverage that can overload the tines, shank, anvil, or vise. [Fraser & Bedell (1962); Anna Lugthart, "Wafer Iron" — cited per the review.]
- Use as a general pry bar or lever unrelated to bending stock — a reasoned extension of the tool's single-purpose fork geometry (thin tines, not built for off-axis leverage). **Flagged explicitly as Haft's own reasoned inference, not an independently sourced misuse account.**
- Cutting or shearing stock — a different hardy-tool family, already resolved from the adjacent side by this corpus's own [[Anvil]] and [[Hardy (Hot) Cut]] entries.

**Dangerous — real, but this entry's thinnest class, stated plainly rather than papered over.**
- ★ **Corrected per the review: the ABANA sharp-edge injury mechanism does not transfer "without modification" to a bending fork.** ABANA's national Safety Guide states a general rule — "Always remove the hardy from the hardy hole before you continue hammering" — and explains its own stated injury mechanism as a sharp edge, characteristic of a cutting hardy. A normal bending fork has blunt tines, a different hazard profile: protrusion into the work area, collision, snagging, pinch/crush between the tines or against the anvil, hot-tool contact, and general obstruction of the working area. The removal rule is still sound general practice, but the laceration mechanism belongs to sharp cutting hardies, not blunt bending-fork tines, and should not be quoted as if it describes this tool directly. This corpus's [[Anvil]] and [[Hardy (Hot) Cut]] entries document a live, honest three-way practitioner disagreement about the removal rule itself (Glenn's rule vs. Frosty's counter-experience vs. a real first-person near-miss) — that disagreement is about cutting hardies and applies there, not here.
- **Pinch points between the tines themselves — a real, plausible, but not independently sourced extension.** The narrow working throat that makes the fork useful is also a genuine two-tine pinch hazard for the hand holding stock close to a hammer strike. **Honest gap, stated directly:** no named, first-person account of a hand injury specifically from a bending fork's tines was located this run, despite repeated, differently-worded searching of I Forge Iron and Reddit's r/Blacksmith.
- **Hot stock/offcut ejection under a mis-struck or over-forced bend.** General hammer-and-anvil hazard, consistent with but not independently re-sourced from the flying-hot-metal hazard already documented in the sibling [[Anvil]] and [[Hardy (Hot) Cut]] entries.
- Eye and hearing protection apply directly, per the same ABANA standing guidance already cited across this corpus for any hammer-and-anvil operation.

**Damaging:**
- **Using the wrong tine gap or diameter for the stock size.** John B.'s and Dave's own named, first-hand accounts (Human Side, above) document this directly — a too-wide or non-parallel gap loses control on larger stock. The entire commercial rationale behind the adjustable (Blacksmiths Depot) and interchangeable-pin (Cincinnati Forge & Tools) variants is engineering around exactly this failure mode rather than mis-fitting a fixed tool.
- **Corrected per the review: there is no sourced claim that under-heated stock cracks the fork.** The earlier draft inferred a "cracked shank/cracked-work" failure from a heat-driven binding phenomenon — a close-fitting hardy shank swelling and sticking in the hole from tool heating — which is a distinct mechanism from stock temperature and does not support a claim that under-heated work cracks the fork. That causal claim is deleted. What is sourced: inspect the fork for cracks or deformation before use; size the fork and mounting for the load; avoid uncontrolled cheater-bar leverage that can overload the tines or shank; and keep a hardy shank loose enough that it does not wedge in the hole under heat.
- **An oversized or over-tight shank jamming and requiring destructive removal.** The same failure mode this corpus's [[Bottom Swage]] and [[Hardy (Hot) Cut]] entries already source from Jock Dempsey (anvilfire.com): tight or tapered hardy shanks "occasionally get stuck and break off in the anvil" — applies without modification to a bending fork's shank; carried forward, not re-derived. This is a shank-fit/heat-driven binding failure, distinct from any claim about stock temperature (see above).

**Beginner-trap:**
- **Assuming a specific maker's hot-steel recommendation is a universal rule, then either over-forcing cold stock the tool/mounting can't take, or under-heating stock for a job that actually needs hot work.** As corrected above, cold bending of sufficiently ductile, light-section stock can be appropriate with a fork, mounting, and leverage sized for the load — but a beginner who doesn't know which case applies risks overloading the tines, shank, anvil, or vise, without an obvious warning sign until the tool or work fails. **Flagged as Haft's own reasoned inference, not an independently sourced first-person beginner account.**
- **Grabbing a fixed-gap fork sized for the wrong stock diameter rather than owning (or improvising) a properly-fitted one.** Directly sourced rationale: the existence of adjustable and interchangeable-pin commercial variants is evidence this mismatch is common enough that manufacturers engineered around it (see Damaging, above); a beginner buying the cheapest single fixed-gap import fork is the population most likely to hit it.
- **Honest gap.** No named, first-person "I learned this the hard way" beginner account specific to the bending fork was located this run.

**Lineage-misuse:**
- ★ **Confusing a bending fork with a bending wrench / scroll wrench, or treating them as strictly identical.** Genuinely unresolved in the source record (see Identity and Variations): general/retail usage often treats the terms as interchangeable, while at least one current maker draws a real, named, catalog-level distinction between a hardy-mounted primary-bend tool and a handheld, multi-slot adjusting tool. **Stated as a live ambiguity, not smoothed into a false resolution** — treating them as always identical, or always distinct, would both overstate what the sourcing supports.
- ★ **Confusing this tool with a scrolling jig.** A bending fork makes and adjusts an individual bend by hand-eye judgment; a scrolling jig is a fixed form the hot stock is wrapped around for identical, repeat-production curves. At least one major retailer's own site taxonomy treats "Bending Forks" and "Scrolling" as sibling but separate categories.
- **Confusing this tool with the anvil horn.** The horn achieves broadly similar sweeping curves freehand, with more feel and less repeatability; the fork trades some of that feel for anchored control. Stated at retail-framing confidence, not an independently sourced named-practitioner comparison.
- **A genuine naming trap for future research, flagged so it isn't repeated.** I Forge Iron's "Fork forging techniques" and "Forging forks" threads (both directly fetched, full text) are **not** about the bending-fork hardy tool at all — they document forging decorative eating/toasting/hay forks (utensils), a completely different object that happens to share the bare word "fork." A researcher (or an AI search pass) searching "forging forks" on this forum will land on the wrong tool entirely — named here explicitly, the same discipline the sibling [[Bottom Swage]] entry applies to Wikipedia's unrelated "Top (tool)" article.

## Correct use

**Genuinely good at:** controlled bends and curves in hot bar or round stock — S-hooks, scrollwork, hook shapes — with more consistent, repeatable curvature than freehand hammering over the anvil horn (retail-level framing, cross-corroborated across multiple product descriptions, not an independently sourced controlled comparison).

**The short version.** The fork seats in the hardy hole (or clamps in a vise); hot stock goes between the tines and is bent by hand, by striking with a hammer, or pulled with a separate bending wrench for reach and leverage inside a partially-formed scroll where a hammer can't get purchase (retail-level, cross-corroborated framing). Technique can be dynamic (moving stock through the fork for a gentle sweeping curve) or static (holding the tool fixed for a sharp, precisely-placed bend) — moderate confidence, retailer-level.

**Honest gap.** No named, first-person, step-by-step technique account comparable to Stokes' FAO sequence (Bottom Swage) or Turley's "nick and break" cutting sequence (Hardy Hot Cut) was located for bending-fork technique specifically. The most directly on-point thread (I Forge Iron, "Bending Fork / Scroll Tool dimensions?") could not be fully fetched this run — only the opening question and the two named replies quoted above under Human Side were recovered.

## Matching (the workbench's first read)
- **Does:** bends/curves/scrolls hot bar or round stock around a controlled radius; produces S-hooks, J-hooks, and the opening curves of scrollwork; the handheld/bending-wrench variant reaches inside a partially-closed scroll to true it up.
- **Suits:** ornamental ironwork, gate and railing scrollwork, hook-making (fireplace tools, coat hooks, S-hooks), general decorative hardware — directly evidenced by ABANA's own National Curriculum Level III grille capstone project, which requires the student to forge multiple hardy stakes and centers on scroll-and-leaf work [abana.org, directly fetched]. General search-synthesis also names it for "bending medium stock" broadly.
- **Kit-fit:** pairs with the [[Anvil]] (the hardy hole) or a bench vise (several current variants are explicitly designed for either mount), a hammer, [[Blacksmith Tongs|tongs]], and the [[Bending Wrench (Hickey)]] for reach inside a forming scroll. **Substitutes for** freehand bending over the anvil horn, trading some tactile freedom for repeatability (retail framing, not an independently sourced controlled comparison). **Pairs with or is substituted by** a dedicated **scrolling jig** for repeat-production identical scrolls — genuinely distinct, per at least one major retailer's own site taxonomy (Bending Forks / Scrolling / Twisting as three separate categories). **Cannot replace** a swage or [[Fuller|fuller]] for cross-section forming, or a hot-cut hardy for severing stock — the same three-way category boundary this corpus's own [[Anvil]] entry already establishes.
- **Not-for (project-keyed):** cutting stock (the hot-cut hardy's job); forming a specific cross-section (the swage/[[Fuller|fuller]]'s job); use as a striking or clamping surface.
- **Access:** genuinely beginner-friendly as hardy tools go in terms of basic operation — no source treats it as high-skill. Its presence in cheap import starter kits is retail bundling evidence, not an independent competence assessment (corrected per the review: starter-kit presence is marketing evidence of entry-level positioning, not proof of beginner suitability on its own). Beginner suitability should be read as conditional on basic hot-work competence and correct stock/tool fit — the real beginner risk sits in heat and stock-fit judgment (see Beginner-trap), not the tool's basic operation.
- **Revival:** a live, current commercial market — at minimum five independently confirmed current makers this run (Blacksmiths Depot/Kayne & Son, Cincinnati Forge & Tools, Ken's Custom Iron Store, FieryFurnaceForge, StrictBlacksmith/Ancient Smithy — the last two shipping internationally via Shopify from Ukraine), plus Centaur Forge's own marketing copy naming bending forks directly ("Hardy tools, pritchel punches, bending forks — they're your precision scalpel"). A maker picks this tool up specifically to move from crude freehand curves into repeatable scrollwork — a real entry point into ornamental ironwork as a discipline distinct from plain forging.

## Anatomy
- **Hardy shank.** Square-section post sized to the anvil's hardy hole; current commercial listings show shank sizes of 3/4", 7/8", 1", and 1-1/4" [Cincinnati Forge & Tools, directly fetched]. At least one maker's variant is sized to "fit most 1-inch hardy holes across the diagonal" rather than a snug square fit [FieryFurnaceForge, directly fetched] — consistent with the general loose-fit hardy-shank discipline already sourced in this corpus's sibling [[Anvil]] and [[Hardy (Hot) Cut]] entries (Jock Dempsey, anvilfire.info: hardy tooling commonly "all fit loose or are too big" — carried forward, not re-derived).
- **The fork / tines.** Two upright pins or rods rising from a base or shoulder above the shank, forming the working gap ("throat") the stock is inserted and levered against. Product specs vary directly with intended stock size: one single-piece forged version specs uprights at "approximately 3/4" round and 1" apart" [Ken's Custom Iron, directly fetched]; another specs a 1-1/4" gap between 2-1/2"-long solid rod tines [Cincinnati Forge & Tools, directly fetched].
- **The gap/throat.** The core design trade-off, stated directly by named practitioner John B. (Human Side, above): too narrow and larger stock won't fit or is forced under strain; too wide and the bend loses control. This trade-off is the direct commercial rationale for the adjustable and interchangeable-pin variants (see Variations).
- **A named, sourced parallelism requirement.** Both John B. and Dave (Human Side, above) independently confirm from real shop experience that the tines must stay parallel — a non-parallel fork makes level scrollwork difficult and gets worse as stock size increases.
- **Honest gap.** No named-author technical manual comparable to Stokes' FAO manual (used by the sibling [[Bottom Swage]] and [[Hardy (Hot) Cut]] entries) was located giving a labeled, dimensioned anatomy diagram of the bending fork specifically. Anatomy here is cross-corroborated from multiple current retailer product specs and named forum practitioners rather than one institutional source — a real, stated difference in sourcing strength from the sibling entries.

## Variations (living)
| Variant | What differs | Source |
|---|---|---|
| Basic/fixed bending fork (single-piece forged) | One solid piece (commonly 1018 steel), fixed tine spacing/diameter, hardy shank | StrictBlacksmith/Ancient Smithy (1018 steel, 1" hardy hole, 7.2" overall length, 1.49 lb); Ken's Custom Iron (1018, 1" hardy hole, ~3/4" round uprights, 1" apart) — both directly fetched |
| Adjustable bending fork (multi-hole shank) | Shank drilled with 4 holes to reposition the pins, varying the gap on one tool | Blacksmiths Depot "Adjustable Bending Fork," 3/4" and 1" hardy shank versions — directly fetched product text |
| Interchangeable-pin / swap-radius bending fork | Welded body, not single-forged; ships with 3 pairs of cut/polished round tubes to change bend radius and gap size | Cincinnati Forge & Tools — "3 pairs of cut and polished round tubes to use to change the radius of your bend and to change the gap size to accommodate smaller stock," shank sizes 3/4"–1-1/4" — directly fetched |
| Hardy Bending Fork vs. Handheld Bending Fork | The hardy version has one slot and a hardy shank; the handheld version has a handle instead, offered in multiple slot widths (3/8", 1/2", 3/4", 1"), worked off-anvil for "forming and adjusting scroll work and hooks" | FieryFurnaceForge, directly fetched, full product text — the corpus's clearest documented example of "a scroll-specific jig that extends the same idea off-anvil" |
| Railroad-spike bending fork (shop-made) | Forged/welded from a repurposed railroad spike, arc-welded rather than forge-welded by a self-described low-skill beginner | I Forge Iron, "Railroad spike bending fork" — reached via search-synthesis, direct-fetch access issue |
| Stand/vise-mounted bending fork (not hardy-mounted at all) | Permanently welded to a vise-stand leg rather than kept as a portable hardy tool, two gap widths plus a separate pipe stub for S-hooks | I Forge Iron, "Stand-Mounted Bending Forks" (JHCC, 2025) — reached via search-synthesis, direct-fetch access issue |
| Vise-clamped shop-made fork (no hardy shank) | Steel plate with round-bar pins, tapped and bolted, built by a hobbyist before he owned an anvil | Workshopshed (Andy, 2013), directly fetched, full post |

**Cross-trade note (retail-level, low confidence):** generic Amazon/Etsy import listings commonly bundle a bending fork into 4–5-piece hardy-tool sets alongside a hot cut, creasing/[[Fuller|fuller]] stake, and bottom [[Fuller|fuller]] — evidence the current retail market treats it as one of the "starter four" hardy tools, alongside the other three tools this corpus's Hardy Tools cluster has now built.

## Trades (where it appears)
**Ornamental/decorative ironwork** — the primary home trade; the ABANA National Curriculum Level III grille capstone project (scroll-and-leaf work, students forge their own hardy stakes) directly supports ornamental scrollwork, though it should not be read as evidence for every gate/railing fabrication claim specifically. **General blacksmithing/forging** — bundled into general-purpose starter hardy-tool sets across every retailer checked. **Gate and railing fabrication** — a plausible, trade-consistent extension of ornamental ironwork, kept at that weight (plausible, not independently sourced to a gate/railing-specific practitioner account this run) rather than stated as directly evidenced. **Farriery** — no direct hand-tool evidence found this run, unlike the sibling [[Bottom Swage]] and [[Hardy (Hot) Cut]] entries, which both found direct farrier-trade patent or retail evidence; a real, honest gap. **Bladesmithing — corrected per the review: not a clean exclusion.** Jim Hrisoulas's *The Master Bladesmith* documents paired bending forks used for forming a flame blade, so this entry no longer states a categorical bladesmithing exclusion; treat bladesmithing as a specialized/occasional use where directly sourced, not absent. [Jim Hrisoulas, *The Master Bladesmith* — cited per the review; a stable library/print citation should replace the current scan-hosting source when available.]

## Lineage

**Ancestors.** The **anvil horn is the direct functional ancestor**, and the fork is best understood as a refinement of horn technique rather than a replacement for it. ABANA's own National Curriculum (Controlled Hand Forging Study Guide, Lesson Four — Bending, Jay Close, *Hammer's Blow*, Spring 2003, read in full) teaches bending entirely over the horn and states the underlying principle directly: "the curve is produced by using the horn as a bending point or fulcrum. Shifting the location of the bar on the horn and changing where and how hard the bar is struck controls the needed curve" — and, tellingly, "The horn is not a forming jig. It is only a variable fulcrum point for bending." This is a genuine, named-author, dated national-curriculum source establishing the pre-fork baseline technique — and it is honestly silent on the bending fork as a distinct tool, a real gap named under History, below. A parallel, older stake-anvil tradition (the "bick iron," see Identity) represents bending against a fixed beak form by a mechanically adjacent but not identical route.

**Corrected per the review: a hardy-mounted bending fork is dated to at least 1907.** James Francis Sallows's 1907 *The Blacksmith's Guide* illustrates a smith's bending fork with a square anvil (hardy) shank and two round prongs — direct documentary dating for the hardy-mounted form specifically, not just the general bending principle. This corpus's own sibling [[Hardy (Hot) Cut]] entry already establishes the hardy hole itself at roughly the 16th century (a named, dated I Forge Iron correction, and Postman's *Anvils in America*, cited secondhand) — but whether a *bending-specific* hardy tool goes back anywhere near that far remains unconfirmed; this entry does not borrow the hole's own antiquity for the fork, and 1907 is the earliest dated anchor located for the fork itself.

**Mechanized analogues and later shop benders — corrected per the review from "descendant chain" to analogy, not proven descent.** ★ **US Patent 1,473,101, "Iron Bender," Albert Hossfeld (Winona County, MN), filed July 19, 1922, granted November 6, 1923** (Google Patents, read in full) documents a hand-operated blacksmith-shop machine for bending flat bars, round stock into eyes, pipe, and tubing — Hossfeld's own text: "This invention relates to a bending machine... adapted to be operated by hand and employed in blacksmith shops, garages, etc." This is a hand-operated, pin-and-roller bench bender that addresses a similar shop-bending need to the hand fork, by an adjustable geared/pinned mechanism instead of a fixed two-tine fork — a mechanized *analogue*, not a documented descendant of the hand tool. The Hossfeld Manufacturing Company (Winona, MN) has manufactured the "Hossfeld Universal® Bender" continuously since 1922, per the company's own current site. Google Patents' own "Cited By" list on the Hossfeld patent shows later bending-machine patents citing it — US 2,502,713 (Fagge, priority 1945/granted 1950), US 4,089,160 (Beaston, "Horseshoe bending apparatus and vise," priority 1977/granted 1978), US 5,626,045 (Bulle, 1994/1997), and US 10,328,476 B2 (Keeling, priority 2014/granted 2019). **Stated honestly, per the review:** a patent citation records a citation relationship, not proof that each later device descends from Hossfeld's machine, still less from the hand bending fork — none of these patents name or critique the hand bending fork, and this list should not be read as a "century-spanning descendant chain" of the fork itself. It documents the separate, real history of mechanized shop bending as a related but independent line.

**Contemporaries.**
- **[[Hardy (Hot) Cut]]** and **[[Bottom Swage]]** — sibling hardy-hole tools, resolved from the [[Anvil]] entry's own family list.
- **The anvil horn** — the tool-free baseline (see Ancestors); the fork trades some freehand feel for repeatable, anchored leverage, per retail framing rather than a controlled named-practitioner comparison (see Lineage-misuse).
- **The bending wrench / scroll wrench** — the fork's true working partner (see Identity), not a rival.
- **A bending jig / scrolling jig used off-anvil** — a genuinely distinct sub-lineage, not a mere variant: a fixed form the hot stock is wrapped around for identical, repeat-production curves, as opposed to the fork's hand-eye-judged individual bend. At least one major retailer's own site taxonomy treats "Bending Forks," "Scrolling," and "Twisting" as three separate but related categories.

## History (Petroski "form follows failure" lens)

**Origin — corrected per the reviewer's 2026-09-03 review: the tool has a documented pre-20th-century record, not the "no pre-20th-century evidence" this entry originally claimed.** James Francis Sallows's 1907 *The Blacksmith's Guide* illustrates a smith's bending fork with a square anvil (hardy) shank and two round prongs — a direct, dated, named-author textual and pictorial record. William L. Ilgen's 1912 *Forge Work* independently documents a "Bending or Twisting Fork," gives sizing guidance for 1/8" and 3/16" material, allows tool or soft steel, and explains the tool's paired use with a bending wrench for scroll shaping. Together these push the documented record back to at least 1907, and this entry does not establish an earlier date or an archaeological lineage beyond that. [James Francis Sallows, *The Blacksmith's Guide* (1907), Wikimedia Commons scan — directly cited per the review; William L. Ilgen, *Forge Work* (1912), Project Gutenberg — directly cited per the review.]

**No dedicated core-form patent was located for the hardy-shanked, hot-work bending fork itself**, despite repeated, differently-worded targeted Google Patents searches and a DATAMP check that returned zero indexed results — only the *machine*-bending Hossfeld lineage (see Lineage) returned real hits. Read plainly, this is consistent with the tool being genuine folk/shop-made kit — cheap, easy to forge from scrap, apparently never worth patenting even as an improvement — rather than a search-effort gap. This entry does not claim to have established the tool's earliest invention date.

**No "form follows failure" patent chain exists for the hand tool itself, unlike its Hardy Cut and Bottom Swage siblings.** The one real failure-driven redesign narrative found this run belongs to the mechanized cousin (Hossfeld, below), read as a related mechanized analogue rather than a proven descendant (see Lineage).

**A museum record exists, with real limits stated plainly.** The Smithsonian National Museum of American History catalogs an iron "Bending Fork," object 1978.2204.068 (accession 1978.2204, transferred by a U.S. Army command). The catalog record supplies no manufacture date or maker — it is a genuine, provenanced museum record, but the 1978 accession year should not be read as a manufacture date, and it does not by itself extend the dated record earlier than the 1907/1912 texts above. [Smithsonian NMAH, "Bending Fork," nmah_654725.]

**Two searched sources, stated at the scope actually checked rather than as universal absences.** Colonial Williamsburg's own primary-source material (*The Blacksmith in Eighteenth-Century Williamsburg*, Thomas K. Ford, Project Gutenberg, full text searched) contains no mention of a hardy tool or bending fork anywhere in James Anderson's period ledgers and account books checked this run — a real, checked absence in that specific source, not a claim about the broader historical record. Separately, the specific Controlled Hand Forging Study Guide PDF searched this run (searched in full for "fork," "hardy," and "bending fork") does not name the bending fork as a distinct tool in the lessons checked, even though bending itself (Lesson Four, via the horn) is a core taught skill — but this is a finding about that one study guide, not about ABANA's curriculum generally: ABANA's own page for its 2024 Level II National Curriculum Zoom class lists "Scrolling Fork with Russ Evertz" directly under "Tools and Techniques," first-party evidence that ABANA's broader instruction does include the tool. [ABANA, "Level II National Curriculum Zoom Tutorials & Coaching," abana.org, Feb. 2024 session — cited per the review.]

## Human Side

**Traditions & trades.** Ornamental/architectural ironwork and scrollwork — the tool's clearly primary documented use across every retail and forum source found. General blacksmithing — a basic kit-tool per multiple forum sources. Farriery — evidenced only indirectly, via the mechanized US Patent 4,089,160 ("Horseshoe bending apparatus and vise," Beaston, 1978, citing Hossfeld) — a real but mechanized-and-adjacent citation, not a direct hand-tool farrier account. **Honest gap:** unlike the sibling [[Bottom Swage]] and [[Hardy (Hot) Cut]] entries, no direct hand-tool farrier-trade source was found for the bending fork specifically.

**Named hands, real and dated — a genuine "shop-made, lost, and reinvented" texture running through this run's sourcing.**
- **"John B."** (I Forge Iron, "Bending Fork / Scroll Tool dimensions?") gives real, first-hand, named-practitioner build specifications: bending forks with jaw widths ranging 3/8" to 3" made from leaf-spring material, his own most-used working range 3/4"–1-1/4" for scroll work. He states a genuine, sourced design-failure mode directly: "If the jaws are not parallel you will have difficulty pulling scrolls level particularly in anvil hardy hole types," and a tool-damage warning: "The jaws also need to have smooth radius faces on the insides or they can marr the workpiece."
- **"Dave"** (same thread) independently corroborates the parallel-jaw failure mode from his own first-hand experience: "I made this mistake on a hardie fork. I used it a number of times on 1/4 to 1/2 bars with no problems. Then I was working some 1-1/2 x 1/4 flat bar and it really was noticeable."
- **Frank Turley** (Turley Forge — already this corpus's most-cited named voice) supplies the "hickey" terminology and the fork/wrench pairing principle, above.
- **★ "JHCC"** (I Forge Iron, "Stand-Mounted Bending Forks," Aug./Sept. 2025 — reached via search-synthesis this run; the opening post and named replies were recovered, but a direct-fetch access issue means the full thread was not read end-to-end, so it is labeled at that verification level here and in References, not "read in full") documents a genuine, dated, real-time craft-development project — permanently welding bending forks of two different gap sizes to a vise-stand leg "after having lost my bending fork one too many times," then iterating a lever-actuated S-hook jig over several posts with photos, including an honest admission that the first version was "a bit awkward" before reworking it with a shortened arm. **Frosty ("The Lucky")** — a named voice already established across this corpus's other hardy-tool entries — responds with real craft-culture texture: "Welding bending forks on your anvil stand is one of those head slapper, DUH moments," and separately notes farrier's anvils' cast-on "turning ears" as an adjacent, historically parallel bending feature.
- **★ Sam Shannon, "Hardy-Hole Bending Fork"** (Alabama Forge Council's *Bituminous Bits*, 2001, reprinted in *The Anvil's Horn*) — a named, dated, step-by-step construction account, corrected into this entry per the review after the earlier draft wrongly reported no such named build account and no Hofi connection. Shannon states the design was generally based on his recollection of an impromptu demonstration by **Tom Clark and Uri Hofi** at the May 2001 Southeast Regional Blacksmithing Conference — he explicitly says he took no written notes at the time and adapted dimensions locally, so the Hofi/Clark connection should be read as Shannon's own recollection of a demonstration, not a claim that Hofi designed or published the form. This is the corpus's actual named-master-smith connection for this tool; the earlier "no source found" framing was wrong. [Sam Shannon, "Hardy-Hole Bending Fork," bamsite.org 2001 newsletter reprint and azblacksmiths.org *Anvil's Horn* reprint — cited per the review.]
- **"Andy from Workshopshed"** (workshopshed.com, London, dated March 13, 2013, full post) gives a real, named, first-person hobbyist account of building a **vise-mounted, non-hardy bending fork** — a steel plate with round-bar pins, tapped and bolted, built before he owned an anvil — direct texture for the off-anvil/vise-clamped variant. A named commenter, **Gene Culver** (Dec. 2014), adds a real, dated follow-up variation: individually adjustable pin bases on 1" square tube stock for variable spacing.
- **A railroad-spike bending fork** (I Forge Iron, "Railroad spike bending fork," reached via search-synthesis after a direct-fetch access failure — flagged as lower confidence than the fully-fetched threads above) — a named beginner's account of arc-welding two railroad spikes into a plate-anvil-mounted fork "since they didn't have much forging skills at that point," grinding the lower spike head flat to seat better. Consistent with this corpus's own repeated pattern of smiths forging hardy tools from scrap (axle stock, jackhammer bits, leaf spring, already documented in the sibling [[Hardy (Hot) Cut]] and [[Bottom Swage]] entries).
- **Corrected gap.** Beyond the Shannon/Clark/Hofi connection above, no source found this run connects Alfred Habermann — already this corpus's named master-smith lineage via the sibling hardy-tool entries — to bending-fork technique or design specifically; searched directly and not found in the sources checked this run, not assumed by association with his other documented work.
- **A content-farm source explicitly checked and rejected.** A WordPress blog ("Breakthrough Blacksmithing," byline "Holier Than Tao") carries numerous bending-fork and hardy-tool posts but is clearly SEO/AI-generated filler (generic "Unlock the Power of..." titles, a fabricated "panel discussion" format with no named real participants, near-identical structure across dozens of unrelated tool posts). Flagged explicitly and excluded from this entry's claims, named directly so a future pass doesn't cite it by accident.

**Corrected per the review: the human-side record is not purely current-era.** The earlier draft characterized this section as an almost entirely 2010s–2020s forum-era record with no dated pre-20th-century usage account. That is no longer accurate: Sallows (1907) and Ilgen (1912) above give this tool a documented textual record from the early 20th century, and Shannon's 2001 article ties a named construction account to a named demonstration by Tom Clark and Uri Hofi. What remains a genuine gap: no named historical *manufacturer* of period bending forks was located in the sources checked this run, and no source establishes the tool's origin earlier than 1907.

## Proof of existence

**Corrected per the review.** The earlier draft claimed no dated museum record and no pre-20th-century documentary evidence existed for this tool. Both claims were false, and are corrected below; proof of existence is stronger than originally stated, though earliest origin and direct ancestry remain unresolved.

- **A provenanced museum record exists, with real limits.** The Smithsonian National Museum of American History catalogs an iron "Bending Fork," object 1978.2204.068 (accession 1978.2204, transferred by a U.S. Army command). The record supplies no manufacture date or maker, so it is a genuine museum record but not itself a dated historical specimen — do not read the 1978 accession year as a manufacture date. [Smithsonian NMAH, nmah_654725.]
- **A documentary record exists from at least 1907.** James Francis Sallows's 1907 *The Blacksmith's Guide* names and illustrates a hardy-shanked smith's bending fork with two round prongs; William L. Ilgen's 1912 *Forge Work* independently documents a "Bending or Twisting Fork" with sizing guidance and its paired bending-wrench use. This is a real, dated, pre-1920s documentary record — this entry does not establish an earlier origin or an archaeological lineage beyond it.
- **No dedicated core-form patent was located** for a hardy-shanked, hot-work bending fork, despite repeated, differently-worded targeted Google Patents searches ("bending fork" + blacksmith/anvil/hardy; "scroll fork"; "hot bending tool" + bar stock/anvil) and a DATAMP check. Two adjacent patents were found, read in full, and directly ruled out rather than stretched to fit: **US 704,521** (Dolan & Estep, 1902, "Metal-Bending Tool") and **US 896,207** (Hazen, 1908, "Metal-Bending Tool") are both bench-mounted, cold-bending, lever-and-jaw devices explicitly built for cold reinforcing-rod/concrete work — a mechanically different tool (clamping jaws + pivoting lever, not a hardy-shanked fork) solving an adjacent but distinct problem.
- **A named 1992 commercial listing** (*Anvil's Ring* advertisement) is evidence of commercial availability by 1992 — not evidence of ABANA endorsement or of a first sale date.
- **What is also real: a live, current, multi-vendor commercial record.** At minimum five independently confirmed current makers (see Revival, above) document the tool's existence and form today.
- **What is also real: the Hossfeld mechanized-analogue patent chain (see Lineage), a dated, named-inventor record from 1922 forward** — strong evidence for the bending *problem's* documented industrial history in mechanized form, though it does not date the hand fork itself and should not be read as its descendant.
- **What remains unresolved:** an earliest invention date and any archaeological lineage for the hand-tool form. This entry does not claim to have established either.
