Nakiri vs usuba, side by side

	Nakiri	Usuba
Bevel	Double — ground both sides	Single — ground one side only
Blade shape	Tall rectangle, flat edge, blunt or squared-off tip	Tall rectangle, flat edge — very similar, often slightly longer and thicker at the spine
Handedness	Works in either hand	Handed — buy right- or left-specific; left-handed versions are rarer and dearer
Best at	High-volume chopping, firmer veg, everyday prep	Very fine slices, decorative cuts, katsuramuki peeling
Learning curve	None — chop straight down	Real. The single bevel steers the blade until you learn to correct for it
Sharpening	Straightforward, both sides on a whetstone	Bevel face plus a flat back — a skill in itself
Typically found in	Home kitchens, including in Japan	Professional Japanese kitchens
Price	Lower — ours run £69.99–£89.99	Higher, as a specialist tool

Why these two get confused

Put a nakiri and an usuba next to each other and most people cannot tell them apart. Both have tall rectangular blades. Both have a flat cutting edge that meets the board along its whole length. Both are roughly the same size, both are thin, and both are unmistakably built for vegetables. The thing that separates them is the one thing you cannot see from a photograph: how the edge is ground.

It helps to know why the shape exists at all. In Japan, most food is eaten with chopsticks, and thin, evenly-cut pieces are far easier to pick up. A tall flat blade that meets the board cleanly along its full length is simply the best tool for producing those cuts — which is why both of these knives, and Japanese vegetable knives generally, look the way they do. If you want the wider family, our guide to the types of Japanese kitchen knives covers the lot.

So the honest summary is that they are close cousins doing the same broad job at different levels of specialisation. The rest of this guide is about which level suits you.

The usuba

Usuba means "thin blade", and that is the whole design brief. It is ground on one face only, with the other face flat — the same construction as a traditional deba or a yanagiba. Grinding all of the edge angle onto one side produces an edge that is keener than any double-bevel knife can practically be, and one that parts an ingredient with very little sideways pressure.

That matters most when the cut is the finished article. Paper-thin slices for a garnish, decorative cuts, and above all katsuramuki — the rotary peel that takes a daikon down into one continuous sheet. A single-bevel blade tracks straight through that kind of work in a way a double bevel does not. The flat midsection also handles peeling, so it doubles as the knife a professional reaches for instead of a paring knife.

A clean cut also leaves a tidier face on the ingredient — less bruising and less discolouration on the cut surface, which shows on a plate of raw vegetables. That is a presentation argument rather than a food-science one, and it is worth saying plainly rather than dressing up.

The costs are real. A single-bevel knife is handed — a right-handed usuba genuinely does not work properly in a left hand, and left-handed ones are less common and usually more expensive. It steers slightly as it cuts until you learn to correct for it, which is why it takes practice. Sharpening is its own discipline, since you are working a bevel face and maintaining a flat back rather than simply alternating sides. And it does not enjoy hard-skinned produce: a pumpkin or a tough squash is a good way to chip a very fine edge.

One genuine practical benefit worth knowing: the tall blade gives excellent knuckle clearance, so there is plenty of room between your hand and the board.

The nakiri

The nakiri is the same silhouette with a double-bevel edge — ground on both faces to form a symmetrical V, exactly like a European chef's knife. That one change removes almost all of the friction. It works in either hand, it does not steer, and it sharpens like any other double-bevel knife on a whetstone. There is no technique to learn.

You use it with a straight up-and-down chop. Some nakiri have a squared-off tip and some have effectively no tip at all, which tells you what it is for — it is not a knife for point work, it is a knife for turning a pile of vegetables into a smaller, neater pile of vegetables quickly. The flat edge means the whole blade lands on the board at once, so you get complete cuts rather than the tail of an onion still hanging together. It is also excellent for crushing garlic and ginger under the flat of the blade.

Even in Japan the nakiri is the domestic knife and the usuba is the professional one, which is a fair guide to who each is for. Ours are built around a hard Japanese-steel core — VG10 or AUS-10 depending on the range — so the edge is genuinely fine despite the knife being the easier of the two to live with. Read more in our VG10 steel guide.

It handles firmer produce than an usuba will tolerate — squash, swede, cabbage — but it is still a vegetable knife with a thin edge, not a cleaver. Do not put it through bone, and do not use it as a general-purpose blade; that is what a santoku or a gyuto is for. Because it does the heavy chopping, expect to sharpen it more often than a knife that only sees light work.

How to choose between them

Five questions settle it for most people.

1. What are you actually cutting? Everyday volume — onions, carrots, cabbage, peppers — points to the nakiri. Fine garnish work, decorative cuts and katsuramuki point to the usuba. Be honest about which of those you do weekly rather than which you would like to.

2. Are you left-handed? This is close to decisive. A nakiri works in either hand. An usuba has to be bought for your hand, and left-handed ones are harder to find and cost more. See what makes a knife left- or right-handed.

3. Will you sharpen it yourself? If you are happy on a whetstone, either works. If sharpening is something you would rather not think hard about, the nakiri is the answer — an usuba's flat back and single bevel are a genuine skill. Our whetstone guide is the place to start either way.

4. How does it need to feel? An usuba is usually the heavier of the two, with a thicker spine. A nakiri is lighter and more nimble for its size. Neither is better; it is about what you want to hold for twenty minutes of prep.

5. What is the budget? Nakiri are the cheaper option — ours run £69.99 to £89.99 — because the usuba is positioned as a professional's tool. That is not a quality gap. A good nakiri will outperform almost any Western vegetable knife regardless of price.

Our nakiri picks

We do not stock an usuba, so these are nakiri. Every price and Judge.me rating below was checked on the live product page on 8 September 2026.

So, which should you buy?

For the overwhelming majority of people reading this: the nakiri. It is easier, cheaper, works in either hand, sharpens without ceremony, and handles the vegetable prep a home kitchen actually generates. Nothing about that is a compromise — it is the knife most Japanese households use for the same reason.

Buy an usuba if the fine work is the point: if you want to learn katsuramuki, if decorative cutting is something you actually do, and if you are content to learn a different sharpening technique to keep it right. It is a beautiful object and a genuinely superior tool for a narrow set of jobs. It is a second knife, not a first one.

And if you want one knife rather than a specialist, buy neither — a santoku or a gyuto is the versatile choice. Our comparisons of santoku vs nakiri and nakiri vs santoku in detail cover that decision, and the best nakiri knives in the UK roundup goes deeper on the shortlist above.

Frequently asked questions

What is the main difference between a nakiri and an usuba?

The bevel. A nakiri is double-bevelled, ground on both faces, so it works in either hand and is straightforward to sharpen. An usuba is single-bevelled, ground on one face only, which makes it keener and better at fine decorative work but harder to use and to maintain.

Is a nakiri or an usuba better for a home cook?

The nakiri, for almost everyone. It has no learning curve, sharpens like any other double-bevel knife, costs less and handles everyday vegetable prep at volume. Even in Japan the nakiri is the domestic knife and the usuba is the professional one.

Is a nakiri single or double bevel?

Double bevel, always. It is ground symmetrically on both faces of the edge, which is why it suits left- and right-handed cooks equally and can be sharpened on a whetstone the same way as a chef's knife.

Are usuba knives harder to sharpen?

Yes. You work the single bevel face and maintain the flat back separately, rather than simply alternating sides. It is a skill worth learning if you own one, but it is a real reason not to make an usuba your first Japanese vegetable knife.

Can a left-handed cook use an usuba?

Only a left-handed one. Single-bevel knives are handed, and a right-handed usuba will steer awkwardly in a left hand. Left-handed versions exist but are less common and usually more expensive. A nakiri has no such problem.

Which knife should I choose on a budget?

A nakiri. They are the cheaper option because the usuba is positioned as a professional tool, and the saving does not cost you performance on everyday vegetable prep. Ours run from £69.99 to £89.99.

Can a nakiri cut hard vegetables like squash?

Yes, within reason. It handles firm produce such as squash, swede and cabbage better than an usuba will, because a double-bevel edge has more support behind it. It is still a thin vegetable knife though, so keep it away from bone and frozen food.

What is katsuramuki?

A traditional Japanese technique in which a cylinder of vegetable, usually daikon, is peeled in one continuous rotating sheet. It is the job the usuba is built for, and the clearest case where a single-bevel blade genuinely outperforms a nakiri.

Do you sell an usuba?

No. We stock double-bevel Japanese-steel knives, so our vegetable range is nakiri rather than usuba. We would rather tell you that plainly than steer you towards something else while implying it is the same knife.
