How to Use a Nakiri Knife

Use a nakiri by push-cutting: set the whole edge on the food, drive it down and slightly forward until it meets the board, then lift, shift and repeat. The one thing you must not do is rock it like a chef’s knife — the edge is dead straight, so rocking lifts most of it off the food and leaves the familiar uncut hinge at the end of the stroke. Get that one change right and a nakiri is the fastest vegetable knife in the kitchen.

The nakiri is a Japanese double-bevel (ryoba) vegetable knife — tall, rectangular, flat-edged, with no point to speak of. The general reference on Japanese kitchen knives puts it alongside the gyuto and santoku as one of the modern double-bevel shapes, as distinct from the traditional single-bevel professional knives like the usuba. If you have just bought one and it feels strange, nothing is wrong with the knife: it is built around a different cutting motion than the one most Western cooks learn first.

Why the shape is the way it is

Three design decisions, each with a consequence you can feel:

• The edge is flat.It meets the board along its whole length at once, so a single downward push severs everything under the blade. There is no curve, which means there is nothing to rock on — and nothing left half-cut at the ends of the stroke.
• The blade is tall. The KAI Seki Magoroku Ginju nakiri we track publishes 51 mm of blade height, which is real knuckle clearance: you can keep your guide hand curled on top of a big onion half and never touch your knuckles to the board. It also makes the blade face wide enough to use as a scoop.
• There is no tip. The front of the blade is squared or gently rounded off. That is a deliberate trade, not an omission: the shape exists for board work, and everything a point does is handled by a second knife.

The grip and the stance

Take a pinch grip — thumb and forefinger on the flats of the blade just ahead of the handle, remaining fingers around the handle. A nakiri usually has no bolster in the way and plenty of blade height, so the pinch grip is comfortable immediately. It matters more here than on a chef’s knife because you are controlling the squareness of the blade to the board, not a rolling motion, and your fingers on the blade are what tell you whether it is square.

Guide hand in a claw, knuckles forward, fingertips tucked. Because the knife is tall, the side of the blade rides against your knuckles very naturally, and the knuckles become the thickness gauge for every cut. Walk them back steadily and the slices come out even without you thinking about it.

The motion, in detail

Down and slightly forward. The downward component does the severing; the small forward push is what makes it a slice rather than a crush — a vegetable cell wall gives way far more cleanly to a blade that is moving along its own edge than to one coming straight down. Then lift the blade clear of the board, shift along, and push again. Lift, shift, push.

Two common errors. The first is rocking, which this page has already laboured, and the fix is simply to notice when the heel or the front of the blade lifts off the food during the stroke. The second is sawing — dragging the knife back and forth. A nakiri is thin and keen enough that it does not need multiple passes, and sawing on a flat edge just scrubs the apex against the board.

There is one legitimate variation: a very slight forward push-cut for soft items like a ripe tomato, where you let the edge travel further along its own length, and a straight drop for hard items like a carrot, where you want maximum downward force with the blade square. Both are still push cuts.

The four jobs it does better than anything else

What a nakiri cannot do, stated plainly

No piercing. No scoring fish skin. No coring a pepper from the inside. No trimming silverskin off a tenderloin. No boning, jointing, or anything that involves a twist. No bone, no frozen food, no squash shell — the edges on the better nakiris are thin and hard, and the Shun Classic nakiri, for example, is a VG-MAX core at the 60-61 Rockwell Shun publishes for that steel with a stated 16° edge per side. That combination cuts beautifully and chips if you treat it like a cleaver. Our meat-cutting page covers what to use instead.

One more honest limitation: at 165 to 180 mm a nakiri is short. A tall, flat, short blade is wonderful on a pile of vegetables and useless on a watermelon. It is a second knife — a very good one — and our first Japanese knife guide sets out the gyuto-then-petty-then-nakiri sequence for a reason.

The weight question, because it decides how it feels

Nakiris vary enormously in mass for an identical blade length, and nobody warns you. Shun publishes 215 g for its 165 mm Classic nakiri — heavier than its own longer chef’s knife, because blade height drives weight. The KAI Ginju, the same 165 mm length in a single layer of stainless, publishes 120 g. The forged Wüsthof nakiri is heavier again, at a published 58 Rockwell in German steel.

A heavy nakiri falls through a carrot and tires your wrist on a long session; a light one needs you to push and feels nimble. Neither is wrong, but if you have used one and hated it, the weight is as likely a culprit as the shape. See our small-hands page for the same argument across other shapes.

Care, sharpening and the board you cut on

Hand-wash and dry immediately, and store it with nothing touching the edge. ZWILLING’s own care page is as blunt about this as any maker gets: no dishwasher, because of “aggressive chemical tablets,” “high temperatures” and “bumps and bangs with other objects,” and a knife needs “its very own space away from other objects, so not simply thrown in the cutlery drawer.” Our dishwasher page covers the mechanism.

Sharpening is ordinary double-bevel work on a stone — but flatness matters more here than on any other shape, in both directions. Your stone must be flat, because a dished stone grinds a convex bevel and a nakiri’s whole advantage is a straight edge that meets the board everywhere. And your strokemust not lift at the ends, because there is no tip to follow. A 1000-grit stone does the work, a 3000 or 6000 finishes it, and at 60 HRC and up you should keep the knife off a ribbed steel rod — Shun’s own FAQ even asks owners not to use a diamond steel for routine honing, because “diamond steels are for sharpening and will remove metal from your knife before it is necessary.”

Finally, the board. The edge touches it along its entire length on every cut, which makes a nakiri the knife most punished by a hard cutting surface. Wood or soft polyethylene; never glass, stone or ceramic. That single habit does more for a vegetable knife’s edge than any sharpening routine — as why knives get dull so fast explains.
