# Gouge Hewn Tool Library · https://hewn.build/tools/gouge Corrected: An independent reviewer read this entry and found corrections. They have been applied to the text, and the reviewer re-checked the correction that mattered most for safety and found it done; the others have not been re-checked yet. The list at the end is the record of what changed. Cite as: "Gouge." Hewn Tool Library, hewn.build/tools/gouge. Reviewed 2026-08-01. --- ## identity - **name:** **Gouge**, a curved- or fluted-edge cutting tool [S1][S2]. Sub-branch names: **carving gouge**, **bowl gouge**, **spindle gouge**, **spindle-roughing gouge**, **firmer gouge**, **paring gouge**, and the historically attested **scribing gouge** (a specifically in-cannel joinery form, forum-sourced only) [S3][S4]. Never match on "roughing gouge" alone: say **spindle-roughing gouge** and bind it to between-centres spindle work. - **family / category:** Related to the chisel family by cutting-wedge form and function, as the tool that cuts concave curves a flat edge cannot register into [S1][S2]. This is a functional comparison with [[Bench Chisel]], [[Paring Chisel]], [[Mortise Chisel]] and [[Ripping Chisel]], not a claim of a single design line. "Everything a flat chisel is, minus the flat blade" is a slogan, not mechanics: mortising, levering, flat registration, impact rating and handle construction do not transfer because both tools cut by a wedge edge `[manual, relayed]` (the reviewer). - **one-line:** A curved- or fluted-edge hand tool used across three distinct disciplines: carving (pushed or, when the specific tool is built for it, mallet-struck against secured work), turning (supported on a lathe rest against rotating work), and joinery/paring (in-cannel, guided by its convex outside profile) [S1][S6][S9]. - **separate axes, not one.** Define independently: (1) sweep or flute profile, (2) main bevel location, (3) blade mass and handle or mounting, (4) intended driving method. Edge profile and shaft section are further axes `[manual, relayed]` (the reviewer). - **cannel:** *Cannel* is the historic term for a chisel or gouge's bevel and survives mainly in gouge vocabulary [S3]. An **out-cannel** carving gouge carries the main bevel on the convex face and is commonly presented with that bevel against the wood, though controlled inverted cuts are also part of carving practice (see Pye below) [S12][S22]. An **in-cannel** gouge carries its primary bevel on the concave face; its convex outside profile (straight along its length, but convex across its width, not a flat chisel back) can guide a scribing or paring cut that reproduces that curve. In-cannel work is associated with coping and, per forum-only sourcing, pattern-making and joinery [S5]. Cannel location does not alone say whether a tool is hand-only or mallet-rated. - **terminology.** *Flute* is the longitudinal concavity of turning tools; *sweep* is a carving edge's transverse curvature. *Wing* is for swept turning profiles; *corner* is for carving sweeps; usage varies among makers `[manual, relayed]` (the reviewer). --- ## ✦ how NOT to use it - **not-for (jobs it should never do).** - Not a pry bar; a general hand-tool caution from industrial hand-tool safety guidance [S24b]. - Not used for a purpose it was not designed for (AAW rule, as quoted by Bucks Woodturners) [S9b]. - Not interchangeable across branches: a carving gouge's shouldered tang is safe to strike lightly with a mallet, while turning gouges are sized for lathe leverage and tool-rest support (LumberJocks, forum) [S26c]. - **Never use a spindle-roughing gouge on bowl or faceplate work.** AAW's *Guide to Gouges* (read this pass) says its small shank can snap under the force of a rotating bowl blank, which has caused numerous accidents, and that it is meant only for roughing between-centres spindle work [S45]. ### dangerous (misuse that injures the user) **Keep hand-carving and lathe safety in separate subsections. They share a sharp edge, not the dominant hazard system.** The lists below are general guidance, not a manual for any lathe or tool; follow the machine maker and competent instruction. #### Static hand carving - Secure the work whenever practical (clamp, holdfast, carving vise). Keep both hands and the body behind and outside the projected edge path; direct cuts away from the body. Dull edges need more force and are more likely to slip [S24]. - Use a sharp, undamaged tool and controlled cuts. Inspect handles, ferrules, tangs and edges. Select a mallet only for a gouge rated to be struck; Pye limits his thin #2½ gouges to light mallet work [S22]. - **Gloves.** A close-fitting task-appropriate cut-resistant carving glove may serve as supplemental protection against some slicing injuries, but it is not puncture-proof, does not make cutting toward a hand safe, and does not replace hand positioning `[manual, relayed]` (the reviewer) [S24]. It is not a universal gouge accessory. **Do not carry this glove recommendation into lathe work.** - A sharp edge can cut during storage, transport, sharpening or setup as well as use. Add edge protection and safe storage. - An often-repeated "never cut toward any part of the body" rule is attributed to Chris Pye; that attribution was not verified against a primary Pye text. The practice is corroborated across independent carving-safety sources [S24]. #### Woodturning (the gouge is one component of a rotating machine) A face shield does not make an insecure blank safe; AAW notes face protection reduces injury severity, while mounting, speed, guarding and position control the source hazard `[manual, relayed]` (the reviewer) [S42]. Checklist, in the sequence of the review, with HSE WIS28 points marked as read this pass: 1. **Instruction.** Obtain competent instruction and follow the lathe manual. HSE: no one should work on a lathe unless competence has been demonstrated [S41]. 2. **Inspect and mount.** Inspect the blank and its mounting; use the correct centers, chuck or faceplate and fasteners. HSE: a drive centre with spurs gives a more positive hold, heavy workpieces may need face plates with the correct screw gauge, and surplus timber should be removed from square stock before turning [S41]. 3. **Rotate by hand** before starting. 4. **Speed.** Select a conservative speed for diameter, balance and condition. HSE: ejection can result from excessive speed, particularly on larger or irregular workpieces during first cuts [S41]. 5. **Line of fire.** Stand out of the line of fire at startup. HSE: ejected workpieces are one of the main causes of accident during hand turning [S41]. 6. **Eye and face protection.** Wear protection appropriate to the operation: full face protection for bowls, vessels, chucks and faceplates, and at least side-protected eye protection for small work, per the reviewer's account of the AAW *Safety Guidebook* (the guidebook did not fetch this pass) `[manual, relayed]` [S42]. HSE lists eye protection and ear defenders as PPE to be provided and used [S41]. 7. **Entanglement.** Contain hair (hairnet or hat), avoid loose clothing especially around the wrists or arms, and remove jewellery and watches (HSE, read this pass) [S41]. **Avoid gloves, loose sleeves, jewelry and loose hair around rotating work** unless a machine-specific risk assessment and authoritative instruction explicitly permit otherwise; AAW instructional material treats gloves as operation-dependent and advises against them for spindle turning `[manual, relayed]` (the reviewer). This is the opposite of the carving-glove allowance above. 8. **Rest.** Keep the tool supported on a rest set close enough for control. HSE: close enough to hold the tool steady with little effort, far enough that "the parallel portion of the chisel is in contact with the rest at all times" during cutting, with the edge at the workpiece centre line [S41]. **No fixed gap is prescribed:** the earlier ½–¾ inch figure is removed, because HSE does not give it; use the machine maker's guidance and keep the tool's supporting section on the rest. 9. **Stop the lathe** before moving the rest, measuring, or changing the setup, and stop for unexpected vibration or noise. 10. **Dust controls** where required `[manual, relayed]` (the reviewer). 11. **Blunt tools** are a listed ejection cause (HSE); keep edges sharp [S41]. 12. **Never use a spindle-roughing gouge on bowl or faceplate work.** Rotating parts and the point of operation are the primary lathe hazards (OSHA Woodworking eTool, `[manual, relayed]` from the reviewer) [S47]. ### damaging (misuse that ruins the tool or the work) - **Roughing gouge on a bowl blank.** A forum member snapped the tang off a Sorby 1¼" spindle-roughing gouge roughing an 8" cross-grain bowl blank; AAW Forum members explain these gouges are built for spindle, long-grain work and note the mistake happens "at least once a month" in their community [S9]. The mechanism, per AAW's *Guide to Gouges*, is the narrow shank transition failing under the intermittent cross-grain loads of a bowl blank [S45]. Grind choice affects cutting behavior but does not make any gouge catch-proof; swept wings change presentation, not the failure mode `[manual, relayed]` (the reviewer). - **Striking a gouge built for hand use.** Pye's thin #2½ gouges are for hand use with "not more than light work with the mallet" [S22]; the general prohibition for hand-only paring gouges is not sourced to a chisel-grade standard (open gaps). - **Wrong sharpening motion** on the concave face (overlong slipstone strokes) [S25b]. ### beginner-trap (mistakes that look fine until they aren't) - **Assuming sweep numbers are standardized across brands** [S5][S1][S4]. - **Pushing the edge in like a scraper** instead of riding the bevel (Anchor–Bevel–Cut), a documented root of catches [S23b]. - **Letting a carving corner dig below the work surface** [S7]. - **Assuming a face shield fixes an insecure blank or excess speed.** ### lineage-misuse (treating one branch like another) - **The roughing-gouge-on-a-bowl-blank case** is the clearest sourced example: a spindle-branch tool used on a cross-grain bowl blank it was never built to resist [S9][S45]. - **Treating a carving gouge like a turning gouge, or the reverse** [S26c]. - **Treating a firmer gouge like a paring gouge, or striking a hand-pressure gouge.** The firmer-versus-paring split matches the chisel pattern, but a gouge-specific source stating the paring prohibition categorically was not found. --- ## correct use *Brief. the workbench holds deep operation.* - **what it's good at:** cutting concave curves, hollows and coves a flat chisel cannot register into; relief and depth in carving; on a lathe, roughing and shear-cutting spindle and bowl profiles [S6][S7][S9]. - **how to use it well (brief):** in static carving, secure the work, keep the guiding hand behind the edge and cuts directed away from the body. For turning, see the lathe checklist under "dangerous." For in-cannel joinery use, the convex outside profile guides the cut [S5]. Keep carving corners from digging below the surface [S7]. Sharpening the curved edge needs a [[Slip Stone|slipstone]] sized to the tool's radius; overlong strokes ride up the curve and round the angle [S25b]. Powered sharpening adds wheel, heat, spark, dust and entanglement hazards that this entry does not cover; defer to the sharpening-system and wheel maker's guidance `[manual, relayed]` (the reviewer). --- ## ✦ matching *The workbench's first read. Every match resolves to a subtype; `tool: Gouge` alone is too broad.* **Required fields for any match** `[manual, relayed]` (the reviewer): discipline, whether the work rotates, work grain and orientation, sweep or flute, main bevel location, edge profile or grind, impact rating, shaft or mounting form, width, workholding, and PPE or training condition. **Matches as `operation → required subtype → material/grain/setup → necessary partner/safety condition`:** - relief hollowing → carving gouge of suitable sweep and strength → secured static work → clamps or holdfast, hands outside the edge path [S24][S26b]. - spindle coves and beads → spindle gouge → between-centres long-grain turning → lathe training, supported rest, correct mounting. - roughing a square spindle blank round → spindle-roughing gouge → between centres only → the same lathe conditions; never bowl or faceplate work. - bowl walls → bowl gouge with suitable flute and grind → correctly mounted bowl blank → lathe training and full face protection. - profile scribing or paring → in-cannel joinery gouge matching the radius its outside surface will reproduce → hand or impact use only as the exact tool is rated. - mallet use → only the exact carving or firmer gouge built and rated for impact. **suits:** sculptural and relief carving; spoon and bowl carving by hand; chair-seat saddling alongside the [[Travisher]] and scorp; bowl and spindle turning matched to stage and subtype; coopering and moulding where a concave-registering tool is wanted [S6][S9][S13][S15][S19b]. **kit-fit.** Pairs with a carver's mallet for firmer or mallet-rated gouges ([[Carver's Mallet]], [[Joiner's Mallet]]); a lathe with a tool rest for turning gouges; [[Slip Stone|slipstones]] sized to the sweep [S25b]; a holdfast, carving vise or non-slip clamp [S24][S26b]. A flat chisel cannot directly follow the same concave radius, though hollows can be produced by many other tools and processes. A gouge is not a substitute for a flat chisel's flat paring or a mortise chisel's levering. **not-for.** Flat paring and hardware mortises (see [[Bench Chisel]], [[Paring Chisel]]); deep square mortises ([[Mortise Chisel]]); a spindle-roughing gouge on any bowl or faceplate blank. **access.** Both carving and turning require training matched to the subtype. Static carving needs secured work, hand discipline and an undamaged sharp tool. Woodturning places the operator close to a rotating workpiece and requires training in mounting, speed, rest position, tool selection and PPE: HSE identifies ejected workpieces, entanglement, trapping, poor support, excessive speed, blunt tools and bad rest position as principal hazards, and says no one should work on a lathe unless competence has been demonstrated (HSE WIS28, read this pass) [S41]. AAW recommends face protection appropriate to the turning operation `[manual, relayed]` (the reviewer) [S42]. No comparative incident data in this entry ranks either branch against a bench chisel, and none is claimed. **revival.** Christian Becksvoort's essay (Lost Art Press) applies David Pye's "manufacture of risk" versus "manufacture of certainty" to carving, arguing small imperfections a hand tool leaves are part of craftsmanship; the same framework appears in the corpus's [[Travisher]] entry [S27b]. --- ## anatomy - **flute / sweep.** The flute is the concave channel along a turning tool; sweep is the carving edge's transverse curvature, roughly #1 (flat) through #11 (near-semicircle "veiner"), with V-tools numbered separately. Tool markings pair sweep with blade width in millimeters (e.g. "5/12" = sweep 5, 12 mm) [S6][S1]. **Sweep numbering is not standardized across makers:** Patrick Chase documents that Pfeil designates carving skews #1S and starts gouges at #2, "generally... equivalent to one number higher" than other makers; an Ashley Iles #5/½" is roughly a Two Cherries #6/12 mm [S5][S1][S4][S10]. Require a profile chart or physical comparison when cross-brand fit matters. - **bevel location** (see identity) [S12]. - **corner.** The two points where the curved edge meets the blade's sides; width is measured corner to corner. Letting a corner dig below the surface risks breaking it and splitting the wood [S7]. - **wing.** The swept-back sides of a turning-gouge edge; wing shape (straight, convex, concave, "rolled over") is a primary variable in catches [S8][S13]. - **heel.** The transition where the bevel meets the blade body; a pronounced heel can act as a fulcrum [S7][S12]. - **tang / socket.** Most carving gouges are tang-mounted; firmer gouges commonly step up to socket construction, as with struck versus hand-pressure chisels [S19b]. - **stock form.** A spindle-roughing gouge, modern spindle gouge and bowl gouge differ in stock form, flute, shank transition, intended grain orientation and permitted leverage, not merely bevel angle. Modern bowl gouges are made from round rod stock with a deep, relatively narrow flute; size is measured across the flutes, so a ½" bowl gouge is typically made from ⅝" rod (AAW, read this pass) [S45]. - **bevel angle varies by branch and by task, and is not a prescription.** Carving gouges commonly run roughly 15–30°; spindle gouges about 25–35° [S7][S8][S13]. Bowl gouges are commonly ground between about 35° and 80° depending on profile and location in the vessel (a long bevel of about 35° to 50° for tall vessel walls, a short bevel of 75° to 80° at the interior transition), with about 60° and a fingernail profile recommended as a nonaggressive beginner setup on a ½" gouge for open bowls of 8 to 10 inches (AAW, read this pass) [S45]. Do not prescribe one angle range for all bowl work. - **bowl-gouge edge families.** AAW describes three: a **traditional** grind (U-shaped wings standing almost straight up, similar to a spindle-roughing gouge, sharpened by rotating the tool), a **fingernail** grind (wings ground back more, usually around 40° to 45°, the Batty 40/40 grind as an example), and a **swept-back wing** grind (the Irish or Ellsworth grind, used for pull cuts, shear scraping and push cuts) (read this pass) [S46]. Flute shape, nose angle, wing profile, bowl form and intended cut interact. --- ## variations (living) **Carving gouges** (secured work; hand pressure, or mallet only for a gouge rated to be struck): - **straight gouge**, **spoon-bent (front-bent)**, **back-bent**, **veiner** (swept past a true semicircle, fine grooves), **fishtail / spade** [S6][S1][S11][S13b]. **Neighboring carving tools commonly sold and numbered alongside gouges (not gouges):** - **V-tool / parting tool**: two flat bevel facets meeting at a point (Woodcarving Illustrated: two rectangular profiles brought to a common point) [S6][S11]. - **Macaroni tool and fluteroni**: a squared-off veiner with three working edges, side edges at right angles to the bottom edge, mainly for relief backgrounds (read this pass) [S11]. Rectangular geometry; shops merchandise it with gouges, but it is not in a family defined by a curved edge. If Hewn chooses a broader "carving-chisel set" grouping, say so explicitly. **Turning gouges** (rotating work on a lathe; each bound to its subtype): - **spindle-roughing gouge:** a wide, shallow/semicircular tool made for between-centres spindle work with grain parallel to the lathe bed; plows a square blank round [S9][S13][S15]. See "how NOT to use it" for its failure mechanism. - **spindle gouge:** lighter, shallower flute; beads, coves, ogees, pens [S13][S14b]. - **[[Bowl Gouge]]:** made from heavier round stock with a deep flute, designed for bowl work, ground in the families above. Named current products: Henry Taylor/Hamlet M2/M42 HSS bowl gouges [S15][S17b]. (Built out separately at [[Bowl Gouge]].) **Firmer and paring gouges** (joinery-scale): - **firmer gouge:** shorter, thicker, parallel-sided, made to be struck, in-cannel or out-cannel by job [S6][S19b][S20b]. - **paring gouge:** a lighter, elongated, in-cannel gouge, tang-mounted. Reserve "hand-pressure only" for a specifically identified paring or finishing model whose maker or authoritative reference says so (see open gaps) [S6][S19b]. Current makers across the range (a dated snapshot, not mechanical data): Pfeil, Ashley Iles (founded 1949), Two Cherries, Flexcut, Henry Taylor (founded 1834) [S10][S4][S16b][S20b]. Treat founding dates and product claims as manufacturer and retailer statements, not independent historical proof. --- ## trades (where it appears, with trade-specific notes) - **woodcarving / sculpture:** relief, figure, spoon and bowl carving, architectural ornament [S6][S22][S27]. - **woodturning:** bowl and spindle turning, taught as its own discipline [S13][S23][S28]. - **joinery / cabinetmaking:** in-cannel paring and firmer gouges for coping and concave details; the "scribing gouge" name is forum-sourced only [S5]. - **chairmaking:** seat-scooping alongside adze, scorp and [[Travisher]] [S29]. - **lutherie / other trades:** no source located; unconfirmed. --- ## lineage - **attested curved-edge and gouge-labelled forms.** Ground-stone gouges (jadeite, diorite, schist) appear in Neolithic toolkits from roughly 7000 BCE alongside axes, adzes and chisels [S14]. Bronze- and Iron-Age socketed metal gouges, Roman *scalprum*, Carolingian forms and later European tools are attested separately (see proof of existence). The continuity of the general idea of a curved cutting edge is visible, but these sources establish existence and form, not a documented transmission chain, and no direct descent is claimed. - **modern alternatives and adjacent processes (not descendants).** - **Rotary carving burrs** (Dremel/Foredom class) are powered alternatives. The corpus's own [[Rotary Burr]] and [[Structured-Tooth Carving Burr]] entries describe a structured-tooth burr as a coarse, fast roughing tool, with a fluted burr or hand gouge expected to follow [R-cross]. General sources say "hand tools shine during the finishing stages" [S24][S25]. Burr-then-gouge is one common workflow among several; rasps, scrapers, abrasives and CNC can also rough or finish to different standards `[manual, relayed]` (the reviewer). - **Carbide-insert turning tools** are adjacent modern turning technology (secondary, MEDIUM) [S16]. - **CNC relief carving** is a production process; carvers commonly finish CNC-roughed work with hand gouges [S16]. - **neighboring tools.** - **[[V-Tool - Parting Tool|V-tool / parting tool]]** and the **macaroni tool**: sold and numbered alongside gouge sets but not gouges (see variations) [S6][S11]. - **[[Travisher]]**: a sequential partner in chair-seat carving, taking over as the fine scoop tool after adze and gouge rough hollowing [S17]. - **[[Drawknife]]**: sequential partner; a drawknife rough-rounds a billet before lathe gouges take over [S18]. - **[[Adze]]**: appears with the gouge in the Mästermyr chest; a gouge-shaped edge can be adze-mounted [S1][S3]. Mechanical comparison only. - **[[Mortise Chisel]]**: the flat-bladed, mallet-struck comparison to the firmer gouge, kept as a comparison where a source supports the exact point [S1][S9]. - **[[Bench Chisel]] / [[Paring Chisel]]**: the paring gouge shares the paring chisel's hand-pressure design intent; the "never struck" prohibition is not sourced for gouges to the same standard (see open gaps) [S9]. > **Petroski lens (corrected).** Chris Pye's 2003 account of the #2½ finishing gouge made with Barry Iles of Ashley Iles is a documented modern design case. The project began with a surface-finishing problem: contemporary #3 gouges were thicker and less flat than Pye's old Herring Bros. gouge, which made it hard for his students to get smooth, lightly tooled backgrounds. Working with Barry Iles, he developed a thinner, flatter sweep and requested a short inner bevel. Pye then demonstrated, with a chisel experiment, that a short bevel pivoting on its heel lifts cleanly out of a scoop where a flat-side-down chisel juddered, and that the inner bevel toughens the edge and permits controlled inverted use [S22]. The juddering scoop was the later demonstration, not the failure that started the collaboration. --- ## history - **origin:** No source located gives a firm invention date or single named originator for the gouge as a type, or for the in-cannel/out-cannel split. Neolithic curved-edge stone tools are attested from about 7000 BCE [S14], and Roger B. Ulrich's *Roman Woodworking* (Yale, 2007) treats the form as present in Egyptian, Greek/Etruscan and Roman toolkits, tracing it through W.L. Goodman's 1964 history [S18b]. Geographic and cultural continuity is not established by these records. - **early English documentation, edition stated.** Joseph Moxon's joinery text, first issued in the 1677–1680 serial run (per the Library of Congress record, `[manual, relayed]` from the reviewer) and verified here in the 1703 third edition via the University of Michigan EEBO-TCP transcription, defines the gouge as "a Chissel having a round edge, for cutting Wood that is to be rounded or hollowed" (item "C.6" in the joiner's tool plate) [S19][S44]. The 1703 edition is a third-edition witness, not the first publication of the passage, and no claim is made that no earlier English description exists. Peter C. Welsh's Smithsonian bulletin supports the plate identification [S19]. - **dated trade evidence, 19th century.** An 1827 Massachusetts carpenter's probate inventory (Amasa Thompson) lists "11 Gouges — $1.19" separate from "13 Chisels — $1.17" [S20]. - **three mechanical actions under one name.** Turning gouges are used with the bevel supported against a rotating workpiece (Anchor–Bevel–Cut); carving gouges are pushed or mallet-struck against secured work; in-cannel paring gouges guide off their convex outside profile for concave joinery. They are different actions, not cosmetic variants of one skill [S23]. No source found dates when carving and turning gouges became separate manufactured product lines. - **a modern refinement of the turning-gouge form.** AAW material supports Stocksdale and Glaser involvement in twentieth-century American turning-tool development; the early-1960s experimental relationship should be distinguished from the early-1970s Turnmaster product line `[manual, relayed]` (the reviewer). The secondary summary used originally was not re-fetched [S16]. - **the Pye/Iles case.** See the Petroski lens above [S22]. - **Sheffield and sweep numbering.** The informal 19th-century "Sheffield List" is the standard most English makers still track, a trade convention and not a universal geometrical scale; sweep numbering "appear[s] to have been somewhat standardized in the 1950s" [S6b]. Keep the maker-mismatch caution next to every sweep-based match. A collector-verified maker chronology anchors the trade: the Addis family (Deptford, London, attested from at least 1792), the Herring Brothers, and Ward & Payne (Sheffield), who bought rights to stamp S.J. Addis's name after his 1871 death, with "S.J. ADDIS / ENGLAND" gouges dating to roughly 1895–1915 [S21]. --- ## ✦ human side - **carving, turning and joinery diverge as trades.** - *Carving:* Chris Pye's *Woodcarving Tools, Materials & Equipment* (GMC Publications) is a standard English-language reference; Pye's 2003 article says "the tighter the longitudinal curve of a tool, the less it should be struck with a mallet, since the shock has to go somewhere" and that his thin-bladed #2½ gouges are for hand use "with not more than light work with the mallet" [S22]. Mary May's Online School (founded 2012) teaches Pfeil-gouge relief carving [S27]. - *Turning:* "Riding the bevel" (Anchor–Bevel–Cut) is the core taught technique [S23]. A Sawmill Creek thread captures five named professionals' bowl-gouge grinds: Richard Raffan ("45 degree bevel on the nose... shortish wings... full convex curve on each wing"), Doug Thompson (50°/40°), David Ellsworth (60–65° "fingernail"/Signature grind, used since 1982, reportedly learned from Liam O'Neill), Stuart Batty (40°) and Mike Mahoney (a straight, non-fingernail profile). Five answers, none resolved into a rule; preserved as practitioner evidence [S28]. - *Joinery and chairmaking:* Peter Galbert worked with toolmaker Tim Manney on a seat-scooping adze; Curtis Buchanan has documented carving a seat with adze and scorp; Peter Follansbee's *Joiner's Work* documents 17th-century gouge-marked joinery layout [S29]. - **transmission and selection struggle (named forum posters; Reddit was inaccessible).** Keith Mathewson relays advice from a Mary May class on a damaged Pfeil #11; Warren Mickley and George Wilson give differing correction techniques [S5]. Baxter Smith, a beginning bowl turner: "I realize that there is 'more than one way to skin a cat' but as a beginning bowl turner I often wonder if I'm working on a dog" [S28]. Commenter Dick Seelenbrandt: "I now understand why I couldn't use the bowl gouge without ruining the pri[e]ce [piece]" [S23]. A chair-seat technique debate weighs gouge, adze and scorp [S17]. - **an injury anecdote (static carving).** A LumberJocks poster describes being "poked... between two fingers with the gouge" while distracted at a carving event, holding the work in one hand and pushing the gouge with the other; another calls bandaging "part of the territory" [S26]. Anecdotal; it illustrates the hazard and is not used as a threshold for it. --- ## ✦ proof of existence *For the Library of Human Making. Museum records support attestation, not a continuous lineage.* **Museum objects catalogued as gouges** (widely separated attestations of curved-edge and gouge-labelled tools; direct continuity and exact use are not established by these records alone): - **Metropolitan Museum of Art, 1994.35.771:** titled "Gouge," stone, tentatively Maya, tentatively before the 16th century.

Caption: "same curved edge, three different jobs and three different safety systems." 2. **Sweep and cannel, side by side.** A cross-section of out-cannel versus in-cannel, with the sweep-number arc (#1 flat through #11 near-semicircle). Label the in-cannel outside surface "convex outside reference surface," not "flat back." 3. **The sub-family lineup.** Straight, spoon-bent, back-bent, veiner, fishtail, firmer, paring, spindle-roughing, spindle and bowl (traditional, fingernail and swept-back grinds). Show V-tool and macaroni tool in a separate "neighboring carving tools" row. 4. *(optional)* **Corner-and-heel anatomy callout.** --- ## The reviewer's corrections (12) - `BLOCKER` — 1. Delete the false OSHA beginner statistic and correct the source classification — Exact claim: “roughly 80% of lathe accidents happen to beginners, concentrated in the first year of operation, per OSHA's own lathe-safety trainer script,” plus the same script as authority for a “face-shield requirement.” - `BLOCKER` — 2. Rebuild the woodturning safety block around the rotating system — Exact claim: The turning safety account is carried mainly by the false 80% statistic, a face-shield sentence, a generic “use the right tool” rule, and “tool-rest overhang past roughly ½–¾ inch.” - `BLOCKER` — 3. Keep carving gloves and lathe entanglement guidance explicitly separate — Exact claim: “cut-resistant gloves are commonly recommended for beginners specifically,” within an entry that immediately transitions to turning gouges. - `SHOULD-FIX` — 4. Correct the Chris Pye design-causality story — Exact claim: Pye and Ashley Iles added an inner bevel “explicitly to fix a named failure (chatter when lifting cleanly out of a concave scoop cut).” - `SHOULD-FIX` — 5. Separate Moxon's verified edition from the publication-priority claim — Exact claim: “first systematic English documentation — read directly: Joseph Moxon, *Mechanick Exercises*, 3rd ed. (London, 1703).” - `SHOULD-FIX` — 6. Correct in-cannel/out-cannel mechanics and avoid “flat-back” shorthand — Exact claim: “Out-cannel … is the standard grind for the great majority of carving gouges, ridden bevel-down”; in-cannel “uses the flat back as the paring reference”; and the three-branch diagram specifies “paring (in-cannel, flat-back registered, hand-pressure only).” - `SHOULD-FIX` — 7. Remove unsupported direct-descent language — Exact claim: “Bronze- and Iron-Age socketed metal gouges directly descend from this stone tradition”; rotary burrs, carbide-insert turning tools, and CNC are “descendants”; and the adze, mortise chisel, and gouge are placed into direct structural/evolutionary lines. - `SHOULD-FIX` — 8. Repair the family boundary around macaroni and V-tools — Exact claim: The gouge family is defined as the “curved-cross-section branch,” but “macaroni tool — a specialty gouge-family member with a rectangular (not curved) cross-section” appears under living variations, while the V-tool is called a cousin rather than a member. - `SHOULD-FIX` — 9. Expand bowl-gouge grind and angle taxonomy — Exact claim: A bowl gouge is “ground with a fingernail grind … or the more aggressive Irish grind,” with a typical bevel of “~45–55°.” - `SHOULD-FIX` — 10. State the spindle-roughing-gouge failure mechanism accurately — Exact claim: A roughing gouge “tang/socket mounting lacks the cross-sectional strength for bowl side-loads and can shatter,” while a bowl gouge's “thicker tang and swept wings resist the catch.” - `SHOULD-FIX` — 11. Reclassify ambiguous archaeological “proof” and weaken continuity claims — Exact claim: The Dorestad object is a “Carolingian iron spoon-bit gouge with surviving organic handle remnant,” folded into a “continuous physical record” of the hand gouge. - `SHOULD-FIX` — 12. Make matching branch-specific and remove comparative-risk overclaims — Exact claim: A flat chisel “cannot” replace a gouge; rotary burrs rough while hand gouges finish; and both carving and turning gouges carry risk “above a flat bench chisel's.”
