Which Japanese knife should you buy?

Pick by how you cook

Almost every “which knife should I buy” question comes down to one of the situations below. Find the row that sounds like you.

The gyuto — the default answer

The gyuto (牛刀) is the Japanese take on the Western chef's knife, and it is the knife most people should buy first. At 210 mm it has enough length to carve, portion and slice; its curved belly lets you rock the blade if that's your habit; and its pointed tip does the fine work — scoring, trimming, separating segments of garlic.

Skip it if your board is small or a long blade makes you nervous. A 210 mm gyuto genuinely wants a board of roughly 40 cm or more to be pleasant. A 180 mm gyuto is a reasonable compromise, but at that point a santoku often feels better balanced.

The santoku — the easier all-rounder

The santoku (三徳, “three virtues”) does the same job as the gyuto in a smaller package. It is shorter, lighter, flatter along the edge, and has a rounded sheepsfoot tip instead of a point. That flat profile suits a straight up-and-down chop rather than a rocking motion — which is how most Japanese cooks actually cut.

Skip it if you regularly carve roasts or break down large cuts of meat: the santoku runs out of blade, and the blunt tip limits detail work. For everyday home cooking, though, it is the knife most people reach for once they own both.

The nakiri — only if vegetables are the point

The nakiri (菜切) is a vegetable specialist: tall, squared off at both ends, and dead flat along the edge so the whole blade meets the board at once. That geometry gives you clean, complete cuts through a cabbage or a stack of carrots, and the extra height keeps your knuckles clear.

Skip it if you want one knife. The nakiri cannot carve, cannot do tip work, and is poor with meat. It is a genuinely delightful second or third knife, and a bad only knife. If you already own a santoku, you do not need a nakiri — you might simply want one.

The petty — a second knife, not a first

The petty (ペティ) is Japan's small utility knife: part paring knife, part miniature chef's knife. Unlike a paring knife, its extra length means it also works on the board — slicing shallots, trimming a fillet, cutting cheese — not just in the hand.

Skip it as a first knife. At 120–150 mm it cannot handle a cabbage, a squash or a roast. Buy an all-rounder first; a petty is the second knife that makes the first one less annoying.

The four, side by side

All four are double bevel, which means they are ground on both sides, cut straight, and work equally well left- or right-handed. The traditional single-bevel knives — deba, yanagiba, usuba — are specialist tools and are handed; see single bevel vs double bevel before you buy one, and left-handed Japanese knives if you cut left-handed.

Beyond the four

The four above cover general cooking. If your kitchen has a specialism, there is usually a Japanese knife built precisely for it: the deba for whole fish, the yanagiba for sashimi, the sujihiki for carving and portioning, the honesuki for jointing poultry, the pankiri for crusty bread, and the kiritsuke or bunka if you want an all-rounder with a more striking tip. You can see every type laid out on the knife types page or compare them directly on the comparison page.

What size to buy

Japanese blades are measured in millimetres, along the cutting edge — 210 mm is roughly 8¼ inches. The practical constraint is your cutting board, not your hands: the blade should be comfortably shorter than the board so you aren't cutting off the edge of it.

• Board 45 cm or larger — a 210 mm gyuto is comfortable; 240 mm if you cook a lot of meat.
• Board around 40 cm — 210 mm gyuto or a 180 mm santoku, whichever you prefer in the hand.
• Board under 35 cm — 165–180 mm santoku or nakiri. A long blade will just be frustrating.

Full detail, including a millimetre-to-inch table and typical sizes per knife type, is in the Japanese knife size guide. If you have smaller hands, this guide covers weight and balance as well as length.

Stainless or carbon

This is the decision people most often get wrong. Carbon steels — Shirogami (white) and Aogami (blue) — sharpen beautifully and take a keener edge than most stainless. They also rust if you leave them wet for a few minutes, discolour when they meet onion or citrus, and need drying immediately after every use.

For a first Japanese knife, buy stainless: VG10, Ginsan or SG2 / R2. You keep almost all of the cutting performance and lose the anxiety. If you like the idea of carbon but not the maintenance, a stainless-clad knife gives you a carbon core with a stainless body — only the thin edge is reactive. The full comparison is in VG10 vs Aogami vs Shirogami.

Wa handle or yo handle

A wa handle is the traditional Japanese one: light, wooden, octagonal or D-shaped, and simply friction-fitted onto the tang. It shifts the balance forward into the blade, which many people find nimbler, and it can be replaced when it wears out. A yo handle is the Western style — riveted scales, heavier, more durable, and more familiar if you've only used European knives.

Neither is better; it is a feel preference, and it is worth holding both if you can. The trade-offs are laid out in wa handle vs yo handle.

The bottom line

One good all-rounder beats a block of mediocre knives. Buy a 210 mm gyuto or a 165–180 mm santoku in a stainless steel, learn to keep it sharp, and add a second knife only when you can name the job it's for.

If you're tempted by a set, read one good knife vs a knife set first. And whichever knife you choose, the thing that actually determines how good it feels is maintenance: sharpening on a whetstone and using a board that won't damage the edge.
