Quick Summary
- Both are Japanese vegetable knives with tall, rectangular-looking blades.
- The usuba is single-bevel, made for professional techniques like katsuramuki (paper-thin peeling).
- The nakiri is double-bevel, lighter and easier to use, sharpen and cut straight with.
- Usuba come in Kanto (square tip) and Kamagata (pointed, sickle-like tip) styles.
- For most home cooks, a nakiri is the better choice; an usuba suits trained or dedicated cooks.

At a glance, the usuba and the nakiri look almost identical: flat edges and tall, near-rectangular blades built for vegetables. The real difference is in how the edge is ground, and that changes how each knife cuts and who it suits.
What Is an Usuba?
Usuba means “thin blade”. It’s a traditional professional vegetable knife, ground on one side only (single bevel) with a slightly hollow back called the ura.
This grind lets a skilled cook make extremely thin, precise cuts. It’s the knife used for katsuramuki, where a vegetable such as daikon is rotated against the blade to produce a continuous, paper-thin sheet.
The Wikipedia entry on the usuba bōchō gives a short overview of its history and use in Japanese kitchens.
Most usuba are 180 to 240 mm long and made from carbon steel, which needs careful drying and occasional oiling. UK retailer Cutting Edge Knives’ usuba guide covers the styles and care.
Kanto and Kamagata Usuba
| Style | Region | Tip | Strength |
|---|---|---|---|
| Kanto usuba | Tokyo (eastern Japan) | Square | Straight cuts and katsuramuki |
| Kamagata usuba | Osaka (Kansai, western Japan) | Rounded, sickle-like, ending in a point | Detailed and decorative work |
What Is a Nakiri?
Nakiri means roughly “leaf cutter” or “vegetable cutter”. It’s a home cook’s vegetable knife with a double-bevel edge, ground evenly on both sides.
Because it’s symmetrical, a nakiri cuts straight without any special technique and works equally well for left- and right-handed cooks. It’s usually lighter and thinner than an usuba and often made from stainless steel.
Learn the technique in our guide on how to use a nakiri knife.
The Key Difference: Single vs Double Bevel
A single-bevel usuba has one wide, angled face and one nearly flat face. This makes the edge extremely keen, but the blade naturally drifts as it cuts, so the cook has to compensate.
A double-bevel nakiri has two matching faces, so it travels straight down. Canadian knife shop Kireaji’s article on usuba and nakiri explains why the nakiri is usually the first choice for home cooks.
Usuba vs Nakiri Compared
| Usuba | Nakiri | |
|---|---|---|
| Bevel | Single | Double |
| Typical length | 180–240 mm | 160–180 mm |
| Weight | Heavier | Lighter |
| Steel | Usually carbon | Stainless or carbon |
| Handedness | Left- or right-handed versions | Works for both |
| Skill needed | High | Low |
| Best for | Katsuramuki, garnishes, professional work | Everyday vegetable prep |
| Sharpening | Single-bevel technique | Like any double-bevel knife |
Cutting with Each Knife
With a nakiri, you use simple push cuts: forward and down, with the whole flat edge meeting the board. It’s fast and forgiving, ideal for onions, carrots, cabbage and herbs.
An usuba rewards practice. Its single bevel peels slices away from the blade, giving remarkably smooth, thin cuts that keep vegetables looking crisp, but it takes time to learn to cut straight.
Sharpening and Care
A nakiri sharpens like most kitchen knives: equal strokes on both sides on a whetstone. An usuba needs single-bevel technique, sharpening the bevel side carefully and only lightly flattening the back so the hollow ura isn’t damaged.
Both are thin and should never be used on bones, frozen food or very hard squash. Hand-wash, dry immediately and oil carbon steel lightly.
Which Should You Buy?
For most home cooks, a nakiri is the better buy. It’s easier to use and sharpen, works for both hands and handles all everyday vegetable prep.
Choose an usuba if you’re training in Japanese cuisine, want to learn katsuramuki or love precise garnishing. If you’re left-handed, make sure to buy a left-handed usuba.
A good nakiri example is the Shun Premier 5.5-inch nakiri. See more in our best nakiri knife guide and our nakiri vs santoku comparison.
Corrections from Our Older Article
Our previous version said the nakiri is “tough to sharpen” and that usuba blades shrink with sharpening while nakiri blades don’t. Every blade loses a little steel with each sharpening; a double-bevel nakiri is actually the easier of the two to sharpen.
How Many Japanese Knives Do You Need?
Traditional Japanese kitchens use three main single-bevel knives: the usuba for vegetables, the deba for fish butchery and the yanagiba for slicing raw fish. Home cooks rarely need all three.
For most people, a gyuto or santoku plus a nakiri covers everything. Add an usuba only if you want to master traditional vegetable techniques.
Learning to Use an Usuba
If you choose an usuba, practise on cheap vegetables like daikon, carrot and cucumber. Start with straight slicing before attempting katsuramuki.
Keep your cuts slow and steady, and watch for the blade drifting toward the bevel side. With time, you’ll learn to correct the angle naturally.
Many cooks find a short lesson or video demonstration helpful. Katsuramuki in particular is easier to learn by watching than by reading.
Kanto vs Kamagata: Which Usuba?
The square-tipped Kanto usuba is the more common style and is easier to find outside Japan. It’s well suited to straight cuts and peeling.
The Kamagata usuba’s pointed tip helps with decorative carving, which is traditionally associated with Kansai cooking. Choose it if garnishing and detailed work matter most to you.
Price and Value
A good usuba usually costs more than a nakiri of similar quality, because traditional single-bevel knives take more skilled grinding. Carbon-steel usuba also need more care.
A mid-priced stainless nakiri gives most home cooks better value and far less maintenance.
Caring for Carbon Steel Usuba
Most traditional usuba are carbon steel, often called white steel or blue steel. These steels take a very keen edge but rust quickly if left wet.
Wipe the blade dry between cuts during long prep, wash it by hand straight afterward and apply a thin film of food-safe mineral oil before storing. A grey patina will form over time, which is normal and helps protect the steel.
Our Verdict
For everyday vegetable prep at home, the nakiri wins on ease, price and versatility. The usuba is the specialist’s tool, unmatched for katsuramuki and fine garnishes in trained hands.
Storage
Both knives have thin, delicate edges, so store them in a wooden saya (sheath), a knife block slot wide enough for the tall blade or on a wood-faced magnetic strip. Never keep them loose in a drawer.
Make sure the blade is completely dry before storing, especially carbon steel.
