The Gyuto: Building the Japanese Chef’s Knife
The gyuto is Japan’s answer to the French chef’s knife and the single most commissioned kitchen pattern in the custom world: a 210-270mm-class (8-10 inch)…

The nakiri from a maker's bench: why the cleaver shape with knife-thin geometry rules vegetables, flat-edge discipline, steel and grind choices.

The nakiri looks like a small cleaver and cuts like a razor: a rectangular, flat-edged vegetable specialist that push-cuts straight down through produce with zero rocking and zero accordion-cut onions. It is the easiest Japanese pattern to build well — no tip to break, no belly to sweep — and the one that converts skeptical home cooks fastest. The catch: its flatness is a precision spec.
Vegetables fail by wedging and by incomplete cuts — the hinge of skin the rocking chef’s knife leaves at the board. The nakiri answers both: a dead-flat edge meets the board along its whole length (no hinge survives), and knife-thin geometry — this is NOT a cleaver; it is a thin blade wearing a cleaver’s outline — parts dense produce without wedging. Height (~50mm / 2 inches) adds knuckle room and a food-moving blade face. The tall flat profile is also the easiest edge in the kitchen to sharpen: no belly transition, no tip taper — just a straight run on the stones.

Blade: 165-180mm (6.5-7 inches) long, ~50mm tall, from 3/32-or-thinner stock. Behind the edge: 0.010-0.015 like its gyuto sibling, full flat or gentle convex grind, 10-15 dps per the angle guide. The precision spec: the edge must BE flat — a 1/32 hollow in the middle leaves that hinge in every cut, and a rocker leaves the ends hanging. True the edge line against the platen with the blade dead-flat on the work table, then check on a surface plate against light. Corners get eased just enough to stop being snag points.

Same hard-fine logic as all thin kitchen work: AEB-L/14C28N stainless at 61-62, 26C3 or 1084 for the carbon crowd, and the nakiri’s broad flat faces are the natural canvas for finishes — migaki polish, forced patina, tsuchime hammer texture (real food-release function on a face this tall), or a vivid hamon on W2 for the showpiece.

The nakiri is a specialist: it does not rock, does not pierce, does not butcher — it turns produce into confetti and that is the whole job. Sell it as the second knife beside a gyuto (the classic pairing), pitch it to the vegetable-heavy cook, and let the flat-edge demo close the deal: one full-length push cut through an onion, no hinge, no accordion. That cut is the product.
