Japanese Chef Knife Guide: Shapes, Steel & How to Choose

A Japanese chef knife is a thin, hard, lightly built blade ground to a 12–15 degree edge, made to slice rather than chop. The all-purpose version is the gyuto; the santoku, bunka and kiritsuke are its shorter or more specialised cousins. Choose by shape, steel and handle.

This guide covers what separates a Japanese chef knife from a Western one, which shape suits your cooking, what the steel and hardness numbers mean, and how to look after the edge. Every knife we forge ships hand sharpened and oiled, and comes with a 99-day home trial and a free lifetime guarantee, so you can test the advice below on your own board.

What is a Japanese chef knife?

In Japan the everyday chef knife is called a gyuto (literally "cow sword"), and in most shops "Japanese chef knife" means a gyuto or one of the shapes derived from it. What makes it Japanese is less the name than the build:

• Thinner blade. A Japanese chef knife is usually 2mm or less at the spine and ground thin behind the edge, so it slides through food instead of wedging.
• Harder steel. Most Japanese-style blades run 58–62 HRC, against 54–57 for a typical German knife. Harder steel holds a finer edge for longer, at the cost of being a little less forgiving of twisting or bone.
• More acute edge. Japanese chef knives are sharpened to roughly 12–15 degrees per side. Western knives sit closer to 20.
• Flatter profile. Less belly than a German chef knife, which suits push-cutting and pull-slicing rather than rocking.
• Lighter handle. Traditional wa handles are octagonal or D-shaped wood with no bolster, which moves the balance forward onto the blade.

Japanese chef knife shapes: which one do you need?

If you are choosing between the two most popular shapes, our Santoku vs Gyuto comparison settles it in five minutes. The Santoku Knife Guide goes deeper on that shape. For the vegetable specialist of the family, see What Is a Nakiri Knife Used For? Uses, Cuts & Care.

Steel and hardness: what the numbers mean

The steel decides how sharp a Japanese chef knife gets, how long it stays that way, and how much care it asks for. These are the constructions we forge and where each one lands.

• High carbon (7Cr17MoV, Torii line). Sharpens fast, takes a screaming edge, and will develop a patina if you leave it wet. The classic Japanese trade-off. See Carbon Steel Knife Care.
• San Mai (SLD tool steel core, Kaiju line). A very hard core steel sandwiched between softer stainless sides. You get the edge retention of tool steel with a blade that shrugs off kitchen moisture. Read San Mai Steel Explained.
• Layered Damascus (AUS-10 core, Feather Forge line). 73 layers of feather-pattern Damascus around an AUS-10 core, full tang. The AUS-10 does the cutting; the layers are real, not etched.
• Layered forged steel (10Cr17MoV core, Bara Forge line). Hardened to 60 HRC with a burl wood handle. A touch heavier than a wa-handled gyuto, which some cooks prefer for big prep.

A hardness of 58–62 HRC is the sweet spot for a Japanese chef knife. Below that, the thin edge rolls; above it, the edge chips more easily on bone or frozen food. Our Rockwell hardness guide explains the scale.

Single bevel or double bevel?

Traditional Japanese knives such as the yanagiba and usuba are ground on one side only, which makes them superb at one task and awkward at everything else. Nearly every Japanese chef knife sold today, gyuto and santoku included, is double bevel: sharpened on both faces like a Western knife, just at a more acute angle. For a home cook a double-bevel gyuto is the right call. It is easier to sharpen, works for left- and right-handers, and handles the full range of prep.

Wa handle or Western handle?

A wa handle is a light octagonal or D-shaped wooden grip with a burnt-chestnut or horn ferrule and no bolster. It pushes the balance point forward so the blade feels lively and the knife weighs very little. A Western (yo) handle is a riveted, full-tang grip with a bolster: heavier, more familiar if you grew up with German knives, and slightly more durable in a busy sink.

Neither is better. Our Torii line uses octagonal maple wa handles; the Kaiju, Bara Forge and Feather Forge lines use full-tang Western-style handles. If you pinch-grip the blade, you will barely notice the difference. If you grip the handle fully, the Western handle will feel more secure.

What size Japanese chef knife should you buy?

An 8-inch (210mm) gyuto is the right first Japanese chef knife for almost everyone. It is long enough to slice a whole cabbage and short enough to control on a standard 12 by 18 inch board. Go to 9–10 inches (240mm) if you break down large roasts or cook for crowds; drop to a 7-inch santoku or bunka if your board is small or you mainly cook vegetables.

Caring for a Japanese chef knife

• Cut on wood or soft plastic. Glass, stone and ceramic boards will chip a 60 HRC edge.
• No bones, no frozen food, no twisting. Use a cleaver or butcher knife for that work; our cleavers are built for it.
• Wash and dry by hand, immediately. Especially high carbon blades. Never the dishwasher.
• Hone lightly, sharpen on a whetstone. A 1000/3000 grit stone at 12–15 degrees keeps the edge honest. Step-by-step in Sharpening a Japanese Chef Knife.
• Store the edge protected. A sheath, magnetic strip or block, never loose in a drawer.

Japanese chef knife questions, answered

What is a Japanese chef knife called?

The Japanese all-purpose chef knife is the gyuto. Santoku, bunka and kiritsuke are related shapes that are also sold as Japanese chef knives; nakiri is the vegetable-only version.

Which is better, santoku or gyuto?

A gyuto is the more versatile choice for a first Japanese chef knife because its length and pointed tip handle meat, fish and vegetables. A santoku is shorter and taller, which suits vegetable prep, small boards and cooks who prefer a lighter, more compact blade.

What is the best Japanese chef knife brand?

There is no single best brand; what matters is a named steel, a stated hardness of 58–62 HRC, a thin grind and a maker who stands behind the knife. Our Torii, Kaiju and Feather Forge lines are hand-forged, hand sharpened before shipping and covered by a 99-day home trial and a free lifetime guarantee.

Are Japanese chef knives worth the money?

If you cook several times a week, yes. A hard, thin Japanese blade stays sharp for weeks between touch-ups and makes every cut cleaner and faster. The trade-off is a little more care: hand washing, a wooden board and no bones.

Shop the range

Every blade in our Japanese chef knives collection is hand-forged, hand sharpened and oiled before it ships, and backed by a 99-day home trial and a free lifetime guarantee. If it is not the sharpest knife you have ever used, send it back for your money back.
