What Is a Nakiri? Japan's Vegetable Knife, Explained
A nakiri is a knife with one job: vegetables. Its name (菜切り) means “greens cutter,” and its tall, rectangular, tip-free blade is shaped for nothing else. For a cook who spends most of their prep time on vegetables, it is a genuine pleasure to use. As a first and only Japanese knife, it is the wrong choice. This guide covers what it does well, where it falls short, how it compares to a santoku and an usuba, and what to look for if you decide you want one.
What a nakiri is built to do
The whole design is about the edge. A nakiri’s blade is nearly flat from heel to tip, and it meets the cutting board along its entire length at once. When you push it down through a carrot or a cabbage, the cut is complete: the pieces fall away cleanly, with none of the half-connected accordion slices a curved blade leaves when its centre touches the board but its ends do not.
The blade is also tall, usually 45 to 60mm, which does two things. It keeps your knuckles well clear of the board, and it gives you a broad flat face for scooping chopped vegetables and carrying them to the pan.
There is no pointed tip. The front of the blade is squared off or slightly rounded, so a nakiri cannot pierce, and it is not built to trim fat, joint a chicken, or do any of the tip work a gyuto handles easily.
The nakiri is the older knife of the two, and the santoku is generally described as a post-war evolution of it: makers gave the nakiri a little curve and a small tip so one blade could also handle the meat and fish that were becoming a bigger part of the Japanese home diet. If you have ever wondered why a santoku looks like a nakiri with the corners softened, that is why.
How you use one
A nakiri rewards a straight up-and-down motion. For most cuts you push straight down, or add a slight forward push for tougher skins. It is not a rocking knife: the flat edge lifts off the board if you try to rock it. Many cooks also use a light tap-chop, letting the blade’s own height and weight do the work through a pile of herbs or greens.
Nakiri vs santoku
This is the comparison most people are actually weighing, because the two look similar and overlap in use.
- Edge shape. A nakiri is fully flat. A santoku has a slight curve toward the front and a small amount of tip.
- Scope. A santoku is an all-rounder: vegetables, boneless meat, most fish. A nakiri is vegetables only.
- On the board. For pure vegetable chopping, a nakiri’s full-length contact is slightly cleaner and more satisfying. For everything else, the santoku is the more useful knife.
If you can only own one Japanese knife, it should be a santoku or a gyuto. A nakiri makes sense as a second knife once you have an all-rounder and you know you do enough vegetable prep to want a dedicated tool for it. Our santoku vs nakiri comparison covers that choice, and the guide to choosing a first Japanese knife covers the first decision.
Nakiri vs usuba
The usuba is the professional version of the same shape: tall and flat, but ground on one side only. That single bevel lets a trained cook take very fine, controlled cuts, including katsuramuki, peeling a vegetable into one long paper-thin sheet.
The cost is the cost of any single-bevel knife. It is sharpened almost entirely on one face, it is made for one hand, and it takes real practice to use well. For a home cook, a double-bevel nakiri gives most of the benefit with none of that learning curve, which is why the nakiri, not the usuba, is the one you see in home kitchens.
Is a nakiri worth buying?
For most people, a nakiri is a want, not a need. A santoku or a gyuto already cuts vegetables well, and a second all-round knife or a petty knife is a more useful thing to buy next.
A nakiri makes sense when three things are true: you already own an all-rounder, you spend most of your prep time on vegetables, and you enjoy the process enough to want a tool built purely for it. For a cook who batch-preps vegetables, cooks a lot of plant-based food, or simply likes the clean feel of full-length board contact, it earns its place on the magnetic strip. For everyone else, the money is better spent elsewhere first. If vegetables are the bulk of your cooking, our guide to the best Japanese knife for cooking vegetables covers the whole decision.
What to look for when buying a nakiri
Grind matters more than steel here
A nakiri lives or dies on how thin it is behind the edge. A thick nakiri wedges dense vegetables apart and cracks them instead of slicing; a well-ground one falls through. When you compare options, weight and blade thickness tell you more than the steel name does.
Size and height
165 to 180mm covers almost all home use. Height is usually 45 to 60mm; taller gives more knuckle clearance and a bigger scooping face, shorter feels a little more nimble.
Steel
Stainless such as VG-10, Ginsan, or AUS-10 is the sensible default and needs only a hand wash and a dry. A carbon steel nakiri, often with a rustic kurouchi finish, takes a finer edge but has to be dried immediately and wiped after acidic vegetables, or it spot-rusts. A new carbon blade can also leave a faint metallic taste on delicate raw vegetables until it builds up a patina, which takes a week or two of use. See our carbon versus stainless guide for the full comparison. On hardness, around 58 to 61 HRC is forgiving; harder steel holds its edge longer but chips more easily against a hard board, and a nakiri spends all its time in hard board contact.
The knife below is an example of that hand-forged carbon end of the market. It is a Blue #2 carbon nakiri with a kurouchi finish, forged by a single craftsman, which also means it is often out of stock. Treat it as a picture of the artisan tier rather than a first purchase, and check availability before you plan around it. Our best nakiri knives roundup covers what is worth buying at each price, including the more available stainless options.

Frequently asked questions
Is a nakiri better than a santoku?
For chopping vegetables, a nakiri's fully flat edge is slightly cleaner and more satisfying. For everything else, a santoku is more useful because it can also handle meat and fish. A santoku is the better single knife; a nakiri is a good second one.
Can you cut meat with a nakiri?
You can slice boneless meat in a pinch, but a nakiri has no tip for trimming and is not built for it. Anything involving bones, joints, or fine trimming needs a gyuto or a dedicated knife.
Do I need a nakiri if I already have a santoku?
Only if you do a lot of vegetable prep and want a dedicated tool for it. A santoku already covers vegetables well. A nakiri is a refinement, not a gap you need to fill.
Should I get a nakiri or an usuba?
A nakiri, unless you are a trained cook who specifically wants single-bevel control for techniques like katsuramuki. An usuba is sharpened on one side, made for one hand, and takes practice; a nakiri gives most of the benefit with none of that.
The short version
A nakiri is a specialist vegetable knife that does one thing very well: clean, complete cuts straight down through produce. It cannot do meat, fish, or tip work, so it belongs in your kitchen as a second knife after a santoku or a gyuto, not as your only one. If you buy one, prioritise a thin grind over a fancy steel, stay stainless for your first, and keep it in the 165 to 180mm range.
