What is a nakiri knife?
The Nakiri knife is the vegetable knife of Japanese cuisine. Its name literally means "vegetable cutter." It is immediately recognizable by its rectangular blade, flat from end to end, like a small cleaver—but unlike a cleaver, the nakiri is thin and lightweight, crafted for precision rather than force.
The Japanese Nakiri knife intended for home cooking is double-beveled (sharpened on both sides), which makes it easy to handle for everyone, both right and left-handed. Its professional single-bevel version, the usuba, is another story we will return to below.
What defines a Nakiri: a flat and rectangular blade, thin and light, double-beveled, sharpened at 15°, with a hard steel core. A blade designed for a single mission, but an excellent one: vegetables.
What is a nakiri used for?
The Nakiri does one thing, and it does it better than any other knife: cutting vegetables. Its geometry was designed for that.
The flat blade, total contact
Unlike a chef's knife or a santoku, whose edge is slightly curved, the Nakiri has a perfectly straight edge. When you lower the blade, it touches the board along its entire length at the same time. The result: the slice is clean and complete, without that final filament holding carrot or cucumber rounds together.
The blade height
The Nakiri is tall. This gives you room for your fingers (the famous claw grip) and allows you to use the flat of the blade as a scoop to transport cut vegetables to the pan or bowl. A detail that saves an incredible amount of time in practice.
What the Nakiri is NOT made for: meat with bones, whole fish, or hard items. Its thin 15° blade would chip. For that, use a gyuto, a boning knife, or a cleaver.
Nakiri, Santoku, or Usuba: do not confuse them
Three Japanese knives that are often mixed up. Here is how to distinguish them.
| Knife | Shape | Bevel | Use |
|---|---|---|---|
| Nakiri | Rectangular, flat | Double | Vegetables, home use |
| Santoku | Dropping spine | Double | Versatile (meat, fish, vegetables) |
| Usuba | Rectangular, flat | Single | Vegetables, professional use |
In short: if you are looking for a vegetable specialist that is easy to live with, go for the Nakiri. If you want one knife to do everything, look at the santoku instead. The single-bevel Usuba requires real technique and is aimed at experienced cooks.
Vegetable cutting technique
The Nakiri is handled like the santoku: vertically, from top to bottom, never in a rocking motion. But its completely flat blade makes this gesture even more effective, provided it is done correctly.
The classic mistake: trying to "saw" back and forth. With a Nakiri, this movement is useless and produces irregular cuts. The flat blade is made to drop straight onto the vegetable—let it do the work.
How to choose your Nakiri
Four criteria separate a Nakiri that will follow you for years from an object that dulls in three months.
1. Steel and hardness
The #1 criterion. Aim for a hard steel core, around 60 HRC or more, capable of holding a fine 15° edge. VG10 is a benchmark: stainless, durable sharpness, corrosion resistant. Steel that is too soft will make the flat blade frustratingly useless, as the slightest loss of sharpness is immediately visible in the cut.
2. Blade flatness
The edge must be perfectly straight, with no dips or bumps. This ensures total contact with the board. A poorly ground blade will leave areas that do not cut.
3. Damascus (optional but appreciated)
A Damascus Nakiri knife wraps the hard core in a folded envelope: unique aesthetics, good resistance, slight food release. The pattern doesn't improve the cut itself, but it is a nice plus for a blade used every day.
4. Length and handle
16 to 18 cm covers most needs. The handle, whether wooden (wa-style or Western), must be comfortable and well-balanced with the blade.
Our recommended Nakiri
Our Shadow Forge Nakiri ticks all four boxes: a VG10 core, a 67-layer Damascus blade that is perfectly flat, sharpened to 15°, and a balanced handle. At 80€, it is one of the best value-for-money options to enter the world of Japanese vegetable cutting, far from the prices of luxury brands.
Maintaining your Nakiri: the critical 15°
First, daily care: hand wash and dry immediately, never in the dishwasher. Use a wooden or plastic board, never glass or stone.
For sharpening, the Nakiri has a special requirement. Because its blade is flat and thin, maintaining the 15° angle is even more critical than on a curved knife: the slightest angular inconsistency results in a spot that cuts less effectively, immediately visible when the edge no longer touches the board uniformly.
On a VG10 core, diamond abrasives are necessary, and maintaining a perfectly consistent 15° along the entire length of a flat blade, freehand, is one of the most difficult sharpening exercises. This is why a guided-angle rotary sharpener is particularly suited to the Nakiri: it mechanically enforces 15° across the entire blade, its diamond discs bite into the VG10, and the edge remains uniform from end to end—without any learning curve.

❓ Frequently Asked Questions
What is a Nakiri knife used for?
The Nakiri is the Japanese knife specialized for vegetables. Its rectangular, flat, and thin blade allows for slicing, julienning, and dicing with remarkable consistency using a simple vertical motion. Its blade height also makes it easy to transport cut food to the pot. However, it is not designed for meat with bones or whole fish.
What is the difference between a Nakiri and a Santoku?
The santoku is versatile (meat, fish, vegetables) with a dropped-spine blade, while the Nakiri is specialized for vegetables with an entirely rectangular and flat blade. The Nakiri offers full contact with the board, ideal for clean vegetable cuts, where the santoku is more versatile but slightly less efficient on vegetables alone.
Is a nakiri a vegetable cleaver?
No, despite its rectangular shape. A cleaver is heavy and thick, made to chop bones and hard pieces by force. The Nakiri, on the contrary, is a thin and light blade designed for precision on vegetables. Using it on bones would chip its fine 15° edge.
How do you use a Nakiri knife?
You cut with a vertical motion, from top to bottom, without rocking. The flat blade hits the entire board at once, which produces clean, complete slices. The hand holding the vegetable curls into a claw to guide the blade and protect the fingers. For julienne and brunoise, you slice first, then cut the slabs into sticks or cubes.
What is the best Nakiri knife?
The best Nakiri is one with a hard steel core (around 60 HRC or more) to hold a fine 15° edge, with a very flat blade and a balanced handle. A VG10 core Damascus Nakiri offers one of the best value-for-money ratios: durable sharpness and a beautiful blade, without paying the price of luxury brands.
How do you sharpen a Nakiri knife?
The Nakiri is sharpened at 15°, and this angle is even more critical than on other knives because its blade is thin and flat: the slightest irregularity shows in the cut. On a hard core like VG10, diamond abrasives are necessary. A guided-angle rotary sharpener mechanically imposes the 15° and ensures a consistent edge along the entire length of the blade, with no training required.
