A nakiri is a Japanese vegetable knife with a rectangular blade and a flat edge. Because the whole edge meets the board at once, it cuts straight down through a carrot or a stack of cabbage leaves in one clean motion, without the thin strips left hanging at the bottom of the cut when a curved knife misses the board.
It is a specialist, but a very good one. It has no real point, it is not meant for meat on the bone, and it will not rock like a chef's knife. For anyone who chops a lot of vegetables, though, it quickly becomes the knife that stays out on the counter.
This guide covers what makes a good nakiri, what to check before you buy, and which type suits which cook.
| Tokyo-style nakiri | Osaka-style nakiri | Usuba | |
|---|---|---|---|
| Blade shape | Squared-off tip, cleaver-like | Rounded, drop-tip corner | Rectangular, heavier |
| Bevel | Double-beveled | Double-beveled | Single-beveled |
| Typical length | About 6 to 7 inches | About 6 to 7 inches | Often longer, up to about 9 inches |
| Who it is for | Home cooks | Home cooks | Mainly professional cooks |
| Learning curve | Low | Low | High, including sharpening |
What a Nakiri Does Well
Our santoku vs chef knife comparison has a short section on where a nakiri fits alongside those two. This guide goes further into what to buy.
A flat edge that meets the board
The nakiri's edge is flat or very nearly flat from heel to tip. Every straight-down chop reaches the board along the whole length of the cut, so slices separate completely. That is its main advantage over a curved chef's knife on vegetables.
Chop and push, not rock
With no curve to rock on, a nakiri is used with a straight up-and-down chop or a push cut forward and down. Cooks who already rock-chop sometimes find it odd for the first week.
A tall, thin blade
The tall blade gives knuckle clearance and doubles as a scoop for moving chopped vegetables off the board. A thin blade falls through dense vegetables instead of wedging them apart, which is why good nakiri are often quite thin behind the edge.
Tokyo and Osaka styles
Tokyo-style nakiri have a squared-off end, a little like a small cleaver. Osaka-style nakiri round off the top corner at the tip. The difference is mostly one of looks and feel; both cut the same way.
Nakiri or usuba
An usuba is the professional Japanese vegetable knife. It is sharpened on one side only, which allows extremely thin cuts but takes real skill to use and maintain. The nakiri is double-beveled, the home cook's version, and is the right choice for almost everyone.
What to Look for in a Nakiri
Once you have picked a style, these details decide whether a nakiri lives up to its reputation.
A genuinely flat edge
The whole point of a nakiri is full contact with the board. Stand it on its edge on a flat surface and look for light underneath. A very slight curve toward the ends is normal on some knives, but dips in the middle defeat the purpose.
Length
Most nakiri fall between about 6 and 7 inches, with 165mm (about 6.5 inches) the common size. That covers onions, carrots, and peppers comfortably. A longer blade, around 180mm, helps with cabbage, large squash, and melons.
Blade thinness
A thin blade is what makes a nakiri glide through vegetables. The trade-off is fragility: thin edges can chip if twisted in dense food such as winter squash or hard sweet potatoes. Cut straight down and do not pry.
Steel
Stainless steel is the easy-care choice. Carbon steel takes a very sharp edge but will darken and rust if left wet. Some nakiri use a black, rough-forged finish called kurouchi on the upper blade; it is a traditional finish and does not change how the edge cuts.
Handle
Japanese handles are lighter, usually round, D-shaped, or octagonal, and put the balance forward toward the blade. Western handles are heavier and riveted. Try both if you can; the one that feels natural when you chop straight down is the right one.
Care
Hand wash and dry it right away, and keep it out of the dishwasher. Store it so the edge does not knock against other metal, especially if it is a thin, hard blade.

Which Nakiri Suits Which Kitchen
Rather than a ranked list of brands, here are the four types worth considering and who each one is for.
6.5-inch stainless nakiri
The standard size in easy-care steel. It handles daily onions, carrots, peppers, and greens, needs no special attention beyond hand washing and drying, and shows you quickly whether a flat-edged knife suits the way you cut.
Look for
- A blade around 165mm
- A flat edge with no dips
- Stainless steel from a named grade
Watch out for
- Not for meat on the bone
- Thin edges chip if twisted in hard squash
Carbon steel or kurouchi nakiri
Carbon steel takes a very keen edge and is easy to sharpen on a whetstone. It develops a gray patina with use, and it must be dried straight away or it will rust. Kurouchi finishes add a rustic look to the upper blade without changing how it cuts.
Look for
- A named carbon or clad steel
- A thin grind behind the edge
- A comfortable Japanese handle
Watch out for
- Rusts if left wet
- Reacts with acidic foods until a patina forms
Keep the Board Put: Get the ROO Mat
Already own a board you like? The ROO Mat sits under any board up to 16 inches wide, grips smooth countertops so it stays put, and catches up to 7 cups of trimmings in its built-in pouch. Board not included. $44.99.
Shop the ROO Mat →7-inch nakiri
The extra length, usually around 180mm, lets you get through a whole cabbage, a large eggplant, or a wide bunch of greens in one cut. It is slightly less nimble on small jobs and needs a board with room for the full blade.
Look for
- A blade around 180mm
- Enough height for knuckle clearance
Watch out for
- Needs a larger board
- Less handy for small, fiddly jobs
Usuba
The single-beveled professional vegetable knife allows extremely fine, decorative cuts, but it is heavier, harder to control, and much harder to sharpen correctly. For almost every home cook, a double-beveled nakiri does the same everyday job with far less fuss.
Look for
- Only if you are committed to traditional Japanese technique and whetstone sharpening
Watch out for
- Steep learning curve
- Single-bevel sharpening takes practice
Upgrade Your Prep Workflow: The ROO Bundle
A nakiri produces more vegetable scraps per minute than almost any other knife, and its straight-down chop depends on a board that does not bounce or slide. The ROO Mat sits under your cutting board and grips smooth countertops like granite, tile, and polished stone, so the board stays planted under every chop. Its built-in pouch at the front edge holds up to 7 cups, which is room for a night's worth of onion skins, carrot tops, and cabbage cores, swept off with the flat of the blade. Already have a board you like? The mat alone is $44.99 and fits boards up to 16 inches wide. Want one that fits? The ROO Bundle adds a rubberwood board for $54.99.

This guide is built from published material data, manufacturer care instructions, and the complaints that come up again and again in buyer reviews and cooking forums. It is not based on hands-on testing, and it does not rank brands, because a ranking without testing would be a guess. Blade lengths and styles described here are typical; individual knives vary, so check the maker's stated dimensions. Where ROO fits the job we say so, and where it does not we say that too.

Frequently Asked Questions
What is a nakiri knife used for?
Chopping, slicing, and shredding vegetables. Its flat edge meets the board along the full length of the cut, so vegetables separate cleanly with a straight-down chop or push cut.
Can you cut meat with a nakiri?
Boneless meat, yes, in a pinch. It is not designed for it, it has no useful point for trimming, and it should never be used on bones or frozen food, which can chip the thin edge.
Is a nakiri worth it if I already have a chef's knife?
If you cook a lot of vegetables, yes. It does the vegetable jobs a chef's knife does, with cleaner cuts and less effort, and it is the second knife many cooks end up reaching for most.
What size nakiri should I buy?
About 165mm, or 6.5 inches, is the common size and suits most kitchens. Choose around 180mm if you regularly cut whole cabbages or large squash.
What is the difference between a nakiri and an usuba?
A nakiri is double-beveled and made for home cooks. An usuba is sharpened on one side only, is usually heavier, and is used mainly by professional cooks for very fine cuts.
Can you rock a nakiri knife?
Not really. The edge is flat, so there is nothing to rock on. Use a straight up-and-down chop or push the blade forward and down through the food.
For most home cooks, a 6.5-inch stainless nakiri with a genuinely flat edge is the right choice, and it makes an ideal partner for a chef's knife. Choose carbon steel if you enjoy sharpening, a longer blade if you cut a lot of big produce, and leave the usuba to professionals. Chop straight down, do not pry, and work on a board that stays put.
