Doe's Foot

identity

• name: Doe's Foot — the standard modern English name, coined by Christopher Schwarz in 2014 as a literal translation of Roubo's French term; also called the notched batten (Richard Maguire's own preferred name, and the name under which the technique was first revived in English) and, in Roubo's original 1769 French, le pied de biche ("deer's/doe's foot" — Schwarz notes the modern French idiom for the same phrase has drifted to mean "crowbar," which is why he chose the more literal, "more evocative" translation) [DF1][DF4][DF7].
• family / category: Workholding → the planing-stop family's lateral-restraint branch — not a stop itself, but the stop's standing working partner, holdfast-held rather than bench-mounted [PS20-cross].
• one-line: A stick with a V-notch cut in one end, pinned down by a holdfast against a board's edge, that catches the sideways push a planing stop alone cannot resist — the fix for the one direction a single-point stop was never built to stop.

✦ how NOT to use it

• not-for:
  • Relying on it with a weak or slipping holdfast — directly sourced (Schwarz's own warning, see matching → not-for) [DF2].
  • Using it as the sole holder for chopping, mortising, sawing, or any multi-directional-force operation — the holdfast's or bench dog's job, not something the notch itself adds beyond the single lateral vector it's built for.
  • Treating it as a full, adjustable-range substitute for a tail vise without owning more than one thickness — Schwarz's own honest limit (see lineage, matching) [DF8].
• dangerous:
  • No injury, near-miss or hazard account specific to the doe's foot was located — both research legs searched independently and found none. That is a research result, not an empty hazard class. The batten itself is a passive stick, but the operation it belongs to is not passive: it involves sawing the notch, striking a holdfast to set and release it, putting hands around a batten and a board, and planing toward stops. A holdfast can release; a batten with a poor grip can rotate; a metal or toothed planing stop can cut a hand or mark the work. ("No stored energy beyond the holdfast's own clamping force" understated this — a struck holdfast under load is stored energy, and it is the thing that lets go.)
    • Secure the batten before sawing the notch, and keep hands clear of the saw's path. The notch is cut on a short offcut, which is exactly the shape that gets held by hand.
    • Set and release the holdfast with the correct striking tool, at the model's specified strike points, and keep the supporting hand out of the blow path.
    • Verify the hold before planing — push the board against the batten by hand and confirm nothing rotates or lifts.
    • Keep hands out of the plane's path, and stop immediately if the board or the batten shifts under the cut.
    • Use a protective scrap or pad where the holdfast bears. Crucible's own manual warns that its pad dents the work unless a protective scrap is used [DF13].
    • Cover or lower a toothed planing stop when it is not in use — a metal toothed stop standing proud of the benchtop is a hand hazard between operations, not during them.
• damaging:
  • A doe's foot attached to the bench with a weak joint can be wrenched off under use — a named, directly sourced concern for the family, not this exact object. Discussing the related "palm" variant, Schwarz notes it needs a robust joint to the planing stop "because the palm is thin... planing stops take heaps of abuse," implying the same thin, lightly-built doe's foot needs a sound attachment method rather than glue alone [DF9]. Reported as a family-level concern rather than a doe's-foot-specific incident.
  • An out-of-true or degraded batten transmits its own inaccuracy to the work, not just to itself. No source states this workpiece-side consequence directly for the doe's foot; it is a reasoned inference from the tool's basic mechanics (a batten that has worn, split, or lost its notch's sharp corner no longer wedges the board cleanly), held at lower confidence than a directly-quoted claim [DF-gap].
• beginner-trap:
  • A weak holdfast is the load-bearing, directly sourced beginner-trap. See not-for above — Schwarz names this as the specific failure mode a beginner is most likely to hit [DF2].
  • Blocking the bench's only nearby holdfast hole. A later Lost Art Press post ("Mind Upon Mind: An Upgraded Doe's Foot," 2026-04-22) raises this directly in a search-engine-surfaced excerpt: using the one holdfast hole nearest the work for the doe's foot can leave a woodworker needing to drill a new hole or find another workholding method for a second task — held at lower confidence than the directly-fetched quotes above, since this run could not fully load the source page's body text [DF18].
  • Not noticing that the batten is rotating. Multiple sources (Schwarz, Sawmill Creek posters) describe a doe's foot pivoting around the holdfast's pad when the board pushes against it, defeating the tool's purpose [DF5][DF14]. (Previously listed as "skipping the traction underside," which turned conditional troubleshooting into a universal build step — see *anatomy.)* The fix is whatever stops the rotation on your bench: re-seating the holdfast, a peg or nail, or a conditional anti-slip treatment — tested in that order, since the treatments are the ones that can damage the benchtop.
  • Reaching for one doe's foot across a wide range of stock thicknesses. Schwarz's own honest limit — a single notched batten is not adjustable for both thin and thick stock, and a beginner who owns only one is likely to force a mismatch rather than build (or borrow) a second [DF8].
• lineage-misuse:
  • Treating the doe's foot as a general-purpose substitute for dog-based workholding, rather than the specific lateral-drift fix it is. A Sawmill Creek thread's own title — "tail vise/wonder dogs (or even doe's foot) for a new bench" — treats the doe's foot as a broad candidate substitute for a full dog-and-vise system; the sourced substitution claims above (Schwarz, Cohen) support it as a genuine tail-vise substitute for planing work specifically, but not as a wholesale replacement for every job a dog-and-vise combination handles (glue-ups, general clamping) [DF14].
  • Treating the Chinese "palm" and the doe's foot as proven to be the same tool. (This entry previously called them "the same device family in a different orientation"; that is more than the evidence carries and is withdrawn.) In English usage a doe's foot placed in front of the work is sometimes called a palm. But the Chinese Lu Ban qi Ellison describes is a fixed V-shaped stop nailed to the bench, not a movable holdfast-held appliance, and the connection rests on a folktale and on visual interpretation of images. Read it as a possible convergent analogue — neither a proven identity nor an unrelated coincidence [DF11].
  • Confusing the doe's foot's function with the winding sticks it happens to share a plate with in the historical record. No functional relationship exists between the two; the only real connection is documentary (both may appear on Roubo's Plate 14 — see lineage) [WS3-cross].

correct use

• what it's genuinely good at: catching the sideways drift a single-point planing stop cannot resist during cross-grain (traversing) planing strokes, and stabilizing wide boards against spinning on the bench [DF1][DF8].
• the core mechanic. Cut a 90° notch in one end of a scrap batten; place the board against the bench's planing stop; set the doe's foot's notch against the board's far edge; pin the doe's foot down with a holdfast through the nearest existing holdfast hole; the planing stroke's cross-grain force wedges the board against both the stop and the doe's foot simultaneously [DF1][DF2].
• use a metal or toothed planing stop for maximum bite, if one is available. Schwarz states the pairing directly: "The notched batten works best if you have a metal planing stop. The harder you push the handplane, the more the metal stop bites into the end grain of your work." [DF2]
• re-seat rather than re-notch for a new board length. Because the doe's foot borrows an ordinary holdfast hole rather than needing a dedicated one, repositioning it for a different board is fast — Katz-Moses names this as a real everyday advantage for flipping a board to deal with shifting grain direction [DF13].
• match the doe's foot's thickness to the stock, or keep more than one. Schwarz's own practice of owning about four doe's feet of different thicknesses is the documented answer to the tool's own range limit (see matching → cannot replace) [DF8].

✦ matching — for the app's read

• does: resists lateral/sideways drift on a board during cross-grain (traversing) planing strokes — the specific failure a single-point planing stop alone cannot stop, because a stop only resists thrust pushed straight into it, not sideways [DF1][PS20-cross]. Secondarily, stabilizes wide boards against spinning/rotating on the bench by presenting two contact points (the notch's "toes") instead of one [DF8]. Secondarily, grips irregular, short, or round stock a holdfast's single pad can't pin alone, per the corpus's own Holdfast entry [H33-cross].
• suits: flattening or traversing wide boards and panels by hand with a scrub or jack plane — the tool's headline job [DF1]; any hand-tool-only bench with no tail vise and no dog holes — Schwarz's own French Roubo bench, built with "just a metal planing stop and a half-dozen holdfast holes," is the documented case the modern technique was built for [DF2]; beginner or minimalist/viseless benches generally, per Maguire's own framing of the revived technique [DF7]; quickly re-orienting a board mid-operation to deal with reversing or shifting grain direction, since re-seating costs nothing beyond moving a holdfast [DF13].
• kit-fit:
  • pairs with (something must pin it down): usually a holdfast — the doe's foot supplies no clamping force of its own. But not only a holdfast: Schwarz's own instruction names holdfasts, clamps, pegs or nails, so match a bench by whether it can restrain the batten against rotation and whether the method allows repositioning, not by whether it has holdfast holes [DF2][DF13][H33-cross]. Usual partner: a planing stop, ideally metal or toothed for maximum bite [DF2][PS20-cross].
  • substitutes for: directly and repeatedly claimed by named practitioners, not inferred — a tail vise. Schwarz: "Paired with a holdfast, the doe's foot can eliminate the need for a tail vise on a workbench." [DF8] Derek Cohen, independently: "amazing as an end vise substitute — for those of you without an end vise" [DF15]. It also substitutes for a second, perpendicular planing stop in the specific job of arresting sideways drift, per the corpus's own Planing Stop entry [PS20-cross].
  • cannot replace: a vise for glue-ups — it supplies no continuous, multi-directional clamping force, inheriting the holdfast's single-point-friction limitation. A shooting board for end-grain squaring — a different geometry problem (registration against a fence, not lateral-drift resistance); no source suggests this substitution is ever attempted. A tail vise's continuous adjustable range across stock thickness — Schwarz's own honest limit: "The downside to using a doe's foot in this orientation is it's not adjustable for really thin or thick stock. You have to switch to a different doe's foot." [DF8]
• not-for (project-keyed): don't rely on it with a weak or slipping holdfast — Schwarz's direct warning: "If your holdfast doesn't hold well, the notched batten will give way when you reach the end of the board next to the planing stop." [DF2] Don't use it as the sole holder for chopping, mortising, sawing, or any operation throwing force in a direction other than the specific lateral vector it's built to catch — that's the holdfast's or bench dog's job on its own. Don't use it for glue-ups — no source discusses this, and none is asserted here.
• access: simple to make and simple to use — after basic sawing, striking-tool, handplane and workholding instruction. Schwarz: "The notch takes two minutes to saw out in scrap and is a definite improvement." [DF2] Maguire's own framing targets it specifically at beginners without a tail vise [DF7]. The earlier "genuinely beginner-safe" rating is withdrawn: no source raises a skill barrier for the batten itself, but the operation around it involves a saw, a struck holdfast and a plane, and no source discussing it was written as safety guidance (see dangerous, below).
• revival: directly and repeatedly framed by named practitioners as the modern answer for no-vise, minimalist, and travel-bench builders and the hand-tool-only movement. Schwarz's own French-oak Roubo bench has "no tail vise or even a strip of dog holes... just a metal planing stop and a half-dozen holdfast holes," and the doe's foot is what makes that bench viable for wide-stock work [DF2]. It is also nearly free — Sawmill Creek consensus actively discourages buying anything, since any two matched scraps work [DF14] — and its five-minute build makes it a genuine, low-stakes first shop-made-tool project.

anatomy

• the notch — a 90° V cut into one end of the batten, forming two contact points Schwarz calls "the toes"; Katz-Moses independently describes the same cut as a "bird's-mouth notch" [DF8][DF13].
• the batten body — no single canonical dimension was confirmed. Schwarz's own working set: a primary doe's foot "about 7\" or 8\" wide," roughly ½" thick, plus "about four of these doe's feet" of varying thickness, because a single notched batten is not adjustable across a wide range of stock thickness — a different thickness requires a different doe's foot [DF8][DF2]. Material is not irrelevant, and this entry previously implied it was. Roubo specifies "a piece of hard wood" [DF3] — the entry's own quoted source — while modern accounts are framed as "shop-made from scrap," which is a statement about cost and convenience, not about material being immaterial. Use sound, straight stock stiff enough not to buckle or split at the notch, with thickness and toe geometry matched to the work. The notch's two toes are the loaded parts, and they are short grain; splitting, buckling and wear are real failure modes that species and section decide. No modern source gives explicit species guidance — that remains an honest gap — but no guidance is not no constraint [DF3][DF-gap].
• the holdfast interface — the doe's foot does not need or use a dedicated hole; every source describes it as pinned through an ordinary, already-existing holdfast hole, repositioned wherever a given board's length requires [DF2][DF13]. Schwarz names a hard prerequisite directly: "You have to have a dang-good holdfast that can cinch down hard and not slip... If your holdfast doesn't hold well, the notched batten will give way when you reach the end of the board next to the planing stop." He recommends a full 1"-diameter holdfast over a 3/4" one for the extra weight and bearing surface this specific use demands [DF2].
• traction underside — a conditional anti-slip option, not a standard build element. Schwarz's current instruction says extra traction may be needed if the benchtop is slippery [DF2]. Test the bare batten first, and if it rotates, use the least damaging treatment that reliably stops it: cork, tread tape, non-slip safety tape of the kind sold for concrete steps (Jennie Alexander's improvement), or sticky-back sandpaper (Schwarz's original suggestion) [DF2][DF5][DF6]. Sandpaper is the most abrasive choice — it can wear a benchtop and trap grit — and nails or pegs are an alternative way to restrain rotation without treating the underside at all.

variations (living)

• the two-holdfast, no-notch original (Schwarz's pre-2013 method) — a plain batten pinned at both ends by two separate holdfasts; functionally superseded by the one-holdfast notched version for convenience, though mechanically simpler to build [DF2].
• the one-holdfast notched doe's foot (the form this entry is built around; demonstrated by Maguire in 2013, described by Roubo in 1769) — one notch, one holdfast, one planing stop; the standard modern form [DF2][DF7].
• the wide-panel "two toes" orientation (Schwarz, 2017) — rather than notching around a board, a wide board is pressed directly against the notch's two outer points, using the doe's foot as a stabilizing wide planing-stop substitute that prevents the board from spinning on the bench [DF8].
• the "doe's ear" (Sawmill Creek) — a two-notch, right-angle variant purpose-built as a tail-vise substitute rather than a lateral-drift catcher [DF14].
• the metal-toothed-stop pairing (Derek Cohen) — a shop-made toothed steel planing stop (O1 steel, 8 ppi, filed sharp) used together with a doe's foot; Cohen reports the combination grips well enough to be "just as stable off centre," his first choice for diagonal planing [DF15].
• the two-notch clamping-angle variant (Yoav Liberman) — a centered 45° notch and an off-center notch on the opposite end of the same batten, for added positioning versatility [DF12].
• the "palm" (Chinese tradition, front-of-work orientation) — the same device family used in front of the work rather than behind it, under a different name and origin story (see lineage, human side) [DF11].
• market check — no current commercial product was located in the named searches as of 2026-07-24. ("Confirmed shop-made-only... current or historical" overstated it: these searches cannot establish historical absence.) Directly searched: Lee Valley/Veritas, Lie-Nielsen, Benchcrafted, Crucible Tool, Woodpeckers, plus a general "doe's foot buy/for sale" web search. Benchcrafted references the doe's foot only as a companion technique alongside its sold Crucible Planing Stop and Crucible Holdfast on its Classic Bench; none of the vendors searched sells a doe's-foot product itself, and no eBay/Etsy listing or retired SKU surfaced in those searches [DF-gap]. This matches, and is corroborated by, the corpus's own Planing Stop and Holdfast entries, which each document numerous commercial stop and holdfast products but never a doe's-foot product.

trades

• Hand-tool woodworking / cabinetmaking — the tool's entire documented home; every source found treats it as a bench-woodworking appliance [DF1][DF2][DF8].
• No non-woodworking trade equivalent for the specific mechanism was confirmed. This run searched directly for a timber-framing or metalworking lateral-restraint analogue and found nothing on point — only general timber-frame lateral-load-bracing content (a structural-engineering concept, unrelated to hand workholding) [DF-gap].
• A real but partial cross-trade design echo, flagged as an inference rather than a documented lineage. Jewelry and engraving benches use a V-notched "bench pin" (sometimes called a "bird's mouth," the same visual metaphor Katz-Moses uses for the doe's foot's notch) to brace work against a saw or file stroke — the same shape idea used against a different stroke direction. This corpus's own Planing Stop entry already documents the bench pin as a cross-trade analogue to the planing stop itself [PS36-cross], and the bench pin now has its own full entry (Run 575). No source states the jewelry trade's bench pin and the doe's foot are historically connected; the parallel is real and worth a future researcher's eye but is not asserted as a documented transmission here [DF-gap].

lineage

• ancestors — Roubo (1769) is the earliest dated description located, not a documented origin. André-Jacob Roubo's L'Art du Menuisier, Volume 1, describes the device in a section on traverse (cross-grain) planing: a piece of hard wood with a triangular notch cut in one end, used together with a holdfast (valet) to hold the far end of a board — set firm with a mallet blow [DF3][DF4][DF16]. Roubo's 1769 first part is the earliest dated description located for this entry; it documents the form and use but does not establish invention. No source earlier than 1769 was found — an honest boundary rather than a stretched "ancient origin" claim, and equally not an origin claim of its own.
• a related-but-distinct 1514 artifact was checked and set aside. A notched stick resembling this device appears in Albrecht Dürer's engraving Melencolia I (1514); Lost Art Press's own research thread concluded, after discussion, that the "Dürer stick" is more likely a straightedge or plumb-reference tool than a workholding pied de biche — a visually similar but functionally different object. Named here explicitly so it is not mistaken for an earlier doe's foot [DF3].
• the naming lineage is a documented two-step relay, not one coinage event — the entry's central finding. (1) Richard Maguire (The English Woodworker) revived the one-holdfast notched-batten technique in a 2013 video and blog post, calling it "the notched batten" and treating it as an old, half-forgotten trick rather than his own invention [DF2][DF7]: "I've followed its journey through many applications and seen in turn the rediscovery of 'The Doe's Foot.' To me though it'll always be the notched batten." (2) Christopher Schwarz, reporting on Maguire's post the same year, later supplied the Roubo etymology and the "doe's foot" translation that became the standard English name: "Roubo calls the device le pied de biche, which in modern French comes out as 'crowbar.' But more literally is 'doe's foot,' which is much more evocative." [DF4] Maguire did not coin "doe's foot"; Schwarz did, translating Roubo's own term after Maguire's revival had already put the technique back into circulation.
• a possible convergent analogue in a Chinese planing-stop tradition — researched by Suzanne Ellison, not Schwarz. (The attribution was wrong in this entry and is corrected: the cited Lost Art Press article is Ellison's.) Ellison describes a Chinese workholding tradition — the "palm" or Lu Ban qi — as a fixed V-shaped stop nailed at the end of the bench, and relays a Bai folktale (translated in a 2006 undergraduate thesis) in which Lu Ban struck his wife with his plane while she steadied work by hand, after which she nailed two palm-shaped pieces to the benchtop instead, giving the device her name [DF11]. Labelled as folktale, and as a functional and formal analogue only. The Chinese device as described is a fixed, nailed V-shaped stop; the doe's foot is a movable, holdfast-held appliance. No transmission, shared lineage or identity is claimed — the evidence is a folktale plus visual interpretation of Chinese images, which cannot establish that these are the same device or a shared naming tradition.
• an older, structurally-related archaeological ancestor exists for the function, not the form. A Roman-era workbench excavated at the Saalburg fort in Germany (dated c. 187 A.D.) uses movable wooden peg "side stops" to resist the same lateral drift — a functional ancestor roughly 1,500 years earlier than Roubo, but a peg system, not a notched batten, and not documented under any name resembling "doe's foot" or "pied de biche" [DF9]. Reported as a functional-lineage note, not a direct ancestor claim.
• no German- or Japanese-named equivalent device was confirmed. This run searched directly for a German equivalent (beyond the Saalburg peg system above, which predates and differs mechanically) and for a Japanese equivalent (traditional tategu-shi joiners typically plane against a pair of nails driven into a standing beam rather than a notched batten, per unauthored search-result synthesis — held at low confidence, no single named source located). Both are honest gaps, not filled with a plausible-sounding invented parallel [DF-gap].
• deepens, without fully resolving, the Roubo Plate 14 dispute Winding Sticks already flagged as an open gap. Every source this run independently consulted describing the pied de biche places it on Roubo's Plate 14 [DF3][DF4][DF16] — the same plate a modern toolmaker separately credits as the pattern for his own winding sticks [WS2-cross]. There is no figure-number conflict, and this entry previously manufactured one. The quoted Roubo translation is internally coherent: figure 17 identifies the notched planing-stop appliance in use, while figure 19 is referenced for the triangular notch and also shows face-planing. Those are complementary references to one plate, not competing identifications [DF3][DF4]. Plate 14 contains multiple workbench and workholding figures, which is the whole explanation. (The invented conflict was being propagated into the Winding Sticks entry; it is withdrawn here.) What remains genuinely open is narrower: verify the original plate directly before making any cross-entry claim about winding sticks — neither this run nor the Winding Sticks entry had access to the printed plate.
• no relevant patent was located in the named searches, as of 2026-07-24. Google Patents and DATAMP were searched for "doe's foot," "notched batten," and related terms, returning nothing relevant [DF17]. That is the claim: a bounded negative search result. A keyword search cannot prove universal historical absence, least of all for a generic form that has gone under variable names.
• contemporaries — the corpus's own siblings it works alongside, not against:
  • Planing Stop — the doe's foot's primary partner; the stop resists straight-on thrust, the doe's foot resists the sideways drift the stop cannot [PS20-cross].
  • Holdfast — the usual partner for the movable modern version, not an absolute requirement. The doe's foot supplies no holding force of its own; something has to pin it down, and Schwarz's current instruction explicitly lists holdfasts, clamps, pegs or nails [DF2][DF13][H33-cross]. A dog-mounted, peg-mounted or nailed version changes how it is set and repositioned but is still a notched stop.
  • Winding Sticks — no functional overlap, but a shared plate in the documentary record (see above) [WS3-cross].

history

• the specific failure it fixes, stated directly in a maker's own words — a clean Petroski case, though not one any source frames in Petroski's own vocabulary. Schwarz states the limitation of a single-point planing stop plainly: "A single-point stop is great for planing narrow stock... But once you start planing wider stock, things get tricky. You either have to keep moving the stock or skew the plane just right to prevent the wood from spinning on the benchtop." [DF1] The doe's foot's fix is equally direct: "Planing across the grain wedges your board against both the planing stop and the doe's foot like magic." [DF1] No source discussing this tool cites Henry Petroski by name — the "form follows failure" framing is Haft's own analytical lens applied to a well-documented practical account, not something these authors state in those terms; flagged honestly rather than presented as if it were.
• the technique's pre-Schwarz English documentation is thin but real. The source is identified and dated: Charles G. Wheeler, Wood-working for Beginners, G. P. Putnam's Sons, 1900 (copyright 1899) — recoverable through Project Gutenberg [DF18]. Its text states that carpenters sometimes nailed a V-notched board to the bench for planing the edges of boards or joists: "Carpenters sometimes nail a small piece of board, with a V-shaped notch at one end, to the top of the bench to hold boards of joist for planing on the edge" [DF18][DF5]. This is a dated primary text, and the "unverified citation" label it previously carried is removed — the English-language documentary record for the general idea runs to at least 1900, well before Maguire's 2013 demonstration. A second, unverifiable secondhand claim from the same comment thread states family testimony of English joiners' use "dating back to at least 1890" — reported as anecdote, not fact [DF5].
• the modern technique's own evolution is itself a documented two-step improvement, mirroring the Petroski logic one level down. Schwarz's original method (used for roughly eight years before Maguire's post) needed two holdfasts and a long batten pinned at both ends, with no notch at all [DF2]. Maguire's 2013 demonstration showed the single-notch method — one holdfast and one batten doing the same job. He is credited here with a documented English-language online revival and practical demonstration, not with inventing the notch: Roubo's translated passage already specifies a triangular notch in 1769, Maguire's own 2013 page calls the technique primitive and old, and in its comments he says his grandfather showed it to him [DF3][DF7]. Schwarz's two-holdfast setup is therefore Schwarz's own earlier personal practice, not the prior state of the art [DF2].
• no foundational patent and no dated antique museum object — expected, and confirmed rather than assumed (see proof of existence).

✦ human side

• André-Jacob Roubo (1769) — the documented origin, in L'Art du Menuisier, Volume 1: describes the pied de biche's construction (hard wood, triangular notch) and its use with a holdfast during traverse planing [DF3][DF4][DF16].
• Richard Maguire (The English Woodworker) — English professional joiner who revived the one-holdfast notched-batten technique in a 2013 video ("The Holdfast and the Batten") and a companion blog post, framing it explicitly as an old, rediscovered idea rather than his own invention, and noting the response surprised him: "I tried to demonstrate an old, clearly forgotten woodworking technique... The response to the video on the Holdfast and The Batten was considerably more [than expected]." [DF7] He later closed his bench-building business, a status note relevant to his standing as a continuing source but not to the tool itself.
• Christopher Schwarz — the entry's most extensively documented human-side source: reported on Maguire's revival in 2013 [DF2], supplied the Roubo etymology and the "doe's foot" rendering in October 2014 — "In Defense of the 'Notched Batten'," dated 2014-10-26, which is the source of the one-year contradiction this entry previously carried [DF4], documented a wide-panel "two toes" variant in 2017 [DF8], researched the Chinese "palm"/Ban Qi parallel in 2016 [DF11], and anchored the tool inside his own book on early workbenches, Ingenious Mechanicks: Early Workbenches & Workholding [DF10].
• Jennie Alexander (author, Make a Chair from a Tree) — contributed a direct construction improvement in the comments of Schwarz's own blog: recommending non-slip safety tape (the kind sold for concrete steps) over sandpaper for the underside grip; Schwarz credits her by name for the resulting "Masonite + 3M Safety-Walk tread" version [DF5][DF6].
• Derek Olson (Old Wolf Workshop) — credited in the same 2014 comment thread as the first to point specifically to Roubo's "plate 14, figure 17" as the depicted pied de biche, ahead of the later translation confirming a related figure on the same plate [DF5].
• Jonathan Katz-Moses (KM Tools) and Yoav Liberman — modern instructional sources: Katz-Moses supplies the "bird's-mouth notch" description and frames the technique's everyday value as letting a woodworker "quickly flip a board around to deal with shifting grain direction or inspect your work" [DF13]; Liberman documents a two-notch variant (a centered 45° notch and an off-center notch on the opposite end) for added clamping-angle versatility [DF12].
• Derek Cohen (inthewoodshop.com) — an independent named practitioner who pairs a shop-made toothed steel planing stop with a doe's foot and calls the combination "amazing," reporting it lets him plane diagonally across a board as his "first choice now" [DF15].
• Sawmill Creek forum contributors — document the "doe's ear," a two-notch, right-angle variant used specifically as a tail-vise substitute, and broad practical consensus recommending 100-grit sandpaper or non-slip material on the underside [DF14].
• A documented folktale, carried as a folktale. The Lu Ban qi / "palm" origin story (see lineage) comes from the Bai ethnic minority of Yunnan Province, relayed by Suzanne Ellison from a 2006 undergraduate thesis translation [DF11]. It is a real and interesting parallel; it is not evidence of a shared lineage with the French/English doe's foot, and this entry no longer treats it as one.
• r/handtools and r/woodworking (Reddit) — a genuine, honestly-flagged absence. This run searched specifically and found no substantive Reddit discussion of the doe's foot; the tool's human record lives almost entirely in named blogs, magazine pieces, and one specific forum (Sawmill Creek), not in Reddit threads [DF-gap].

✦ proof of existence

• earliest dated depiction located: André-Jacob Roubo, L'Art du Menuisier, Volume 1, Plate 14, published 1769. Plate 14 carries several workbench and workholding figures: figure 17 shows the notched appliance in use, and figure 19 is cited for the triangular notch and also shows face-planing — complementary references, not a dispute [DF3][DF4]. This documents the form and its use; it does not establish invention. The plate itself is reproduced in full in L'Art Du Menuisier: The Book of Plates (Lost Art Press facsimile edition, ed. Christopher Schwarz, 2014); the original 1769 edition and later scans are also held by NYPL Digital Collections and the Internet Archive [DF16].
• no museum/collection accession record was located for a doe's foot / pied de biche specifically, at any institution searched. This is consistent with the device's nature — a disposable, shop-made scrap appliance unlikely to be individually catalogued or preserved as a discrete museum object, rather than an oversight in this run's research [DF-gap].
• no relevant patent was located in the searches named (Google Patents, DATAMP, 2026-07-24) — a bounded negative search result, not proof that no filing exists [DF17].
• an unanswered open question in the primary literature itself. A Lost Art Press commenter asks, in the original 2014 thread, whether an item shown on Roubo's Plate 11 (stuck to a workbench leg) is also a doe's foot — no one in the thread answers, and this run found no follow-up resolving it. Reported here as a genuine open question in the sourced record, not something this run resolved [DF5].
• archaeological evidence exists for the functional family, not the specific device. The Roman-era Saalburg workbench (Germany, c. 187 A.D.) has archaeologically-attested peg-based lateral restraints performing the same function, roughly 1,500 years before Roubo — a functional ancestor, not a documented pied de biche [DF9].

The reviewer's corrections (11)

• SHOULD-FIX — 1. — Exact claim: “Roubo (1769) is the confirmed, dated origin point.”
• SHOULD-FIX — 2. — Exact claim: “Maguire’s innovation was the single notch” and “the one-holdfast notched doe’s foot (Maguire’s innovation).”
• SHOULD-FIX — 3. — Exact claim: The summary says Schwarz supplied the name “later that year” after Maguire’s 2013 revival; the identity section says 2014.
• SHOULD-FIX — 4. — Exact claim: Two sources “disagree on the exact figure number” and the Plate 14 dispute remains open because one names figure 17 while another names figure 19.
• SHOULD-FIX — 5. — Exact claim: The Chinese “palm” or “Ban Qi” is “the same device family in a different orientation,” and the connection comes from “Schwarz’s own research.”
• BLOCKER — 6. — Exact claim: “genuinely beginner-safe,” “The DANGEROUS misuse class is honestly and fully empty,” and “no stored energy beyond the holdfast’s own clamping force.”
• SHOULD-FIX — 7. — Exact claim: A holdfast is a “non-negotiable dependency,” every source uses an existing holdfast hole, and the doe’s foot “does not need or use a dedicated hole.”
• SHOULD-FIX — 8. — Exact claim: No source gives species guidance and the universal scrap framing implies species does not matter.
• SHOULD-FIX — 9. — Exact claim: Traction material is a standard anatomy element and skipping it is a beginner trap.
• MINOR — 10. — Exact claim: No patent and no commercial product were “confirmed,” including across all historical products.
• MINOR — 11. — Exact claim: The 1900 Wood-working for Beginners passage cannot be independently attributed or dated.
