Yoshimi Kato Forged Ginsan Tsuchime Gyuto 240mm

Both are all-purpose Japanese knives, and for most home cooks either will handle the bulk of daily prep. The choice comes down to length, blade shape, and how you like to cut.

A gyuto is the Japanese chef's knife - typically 210 to 240mm with a gently curved edge that lets you rock and slide through cuts as well as chop. The extra length and pointed tip give you reach and versatility, from proteins to large produce.

A santoku is shorter, usually 165 to 180mm, with a flatter profile and a rounded sheep's-foot tip. It rewards a straight up-and-down push cut, feels nimble in smaller hands or tight kitchens, and is the classic Japanese household knife.

Rule of thumb: choose a gyuto if you want one do-everything knife with more reach, or a santoku if you prefer a compact, easy-to-control blade. Plenty of our customers end up owning both.

A gyuto is the Japanese chef's knife — a double-bevel general-purpose kitchen knife. The name literally means "beef sword," and it's still a fair job description: you use it to slice meat, chop vegetables, dice aromatics, and break down fish. If you own one good knife, this is the shape it should be.

Versus a typical Western chef's knife, a gyuto is thinner behind the edge, sharpened to a keener angle (roughly 15–18° rather than 20–22°), and usually made from harder steel — often above 60 HRC. That's what makes it slice so cleanly: less crushing, less tearing. The trade-off is a more brittle edge, so it asks to be honed and sharpened more attentively than a soft Western blade.

Blades run from compact 150mm to long 240mm, but for a home kitchen I'd start at 210mm — my sizing FAQ explains why.

In a home kitchen I'd pick a 210mm gyuto. It's the sweet spot: long enough for a full slicing stroke, short enough to stay nimble on a normal cutting board and easy to control while you're still building your technique.

Step up to a 240mm only if you regularly break down large cuts — roasts, whole fish, big vegetable prep. The extra length means longer strokes and fewer passes, but it also means more weight and a bigger board; if the tip is hanging off your bench you're fighting the knife, not cooking with it. If you're mainly doing vegetables and portions, the 240 gives you nothing you'll use.

For a first gyuto, buy a well-made stainless one around 210mm in the low hundreds. Traditional carbon steels (white and blue paper steel) cut and sharpen beautifully, but they rust if you leave them wet — learn one variable at a time. Better steel is step two.

Get the 210mm. We only point people to a 240mm when they have about 45cm of usable board, cook in volume, and regularly break down big roasts or whole fish.

On the gyutos we've measured for our product pages, the extra length is real. The 210s have a median edge of 213mm from heel to tip and the 240s 240mm. The 240s are also heavier, 195g against 163g at the median, and a touch taller at the heel, 51mm against 48mm. End to end a 240 runs about 39cm and a 210 about 36cm.

That length buys you a longer stroke. A 240 goes through a big piece of meat in one or two pulls and moves a board of chopped vegetables with less shuffling. It costs you board space and control. On a small board the tip hangs off the edge, and fine work like herbs and shallots feels like more knife than the job needs.

If you want the sharpest possible edge and don't mind caring for a harder, more brittle blade, buy Japanese; if you want a tougher, more forgiving knife that can take abuse and be honed casually, buy German. Japanese knives, like the gyuto, are ground to a much sharper edge angle, typically 15 to 18 degrees compared to 20 to 22 degrees on a western chef's knife, and use harder steel that can exceed 60 HRC, which is why they cut with such precision but also chip more easily. German knives are softer and more ductile, so they resist chipping and bend rather than break, but they won't hold that razor-sharp edge as long.

A Japanese knife is not the right choice if you regularly cut through bones, frozen food, or hard squash, or if you're used to rocking the blade hard on a cutting board, that lateral stress and impact can chip the edge. German knives are the better everyday beater for heavy prep, but you'll trade away the effortless slicing and fine edge retention that make Japanese steel so satisfying.

The gyuto, literally "beef knife," is the Japanese take on a French chef's knife, with a flatter profile that suits push-cutting and slicing. That acute blade geometry is only possible because of the harder steel used, a typical western knife at 20 to 22 degrees would roll or dull quickly at 15 to 18 degrees, whereas the harder Japanese steel holds that finer edge. That's the core trade-off: hardness buys sharpness and edge retention, but it also makes the blade more brittle, so you need a gentler technique and a wooden or plastic board.

Ginsan steel, also known as Silver #3 or G3, is a stainless steel made by Hitachi Special Steel in Japan, containing 1.02% carbon and 13.75% chromium, and it is used in Japanese knives because it combines the sharpness and ease of sharpening of carbon steel with the rust resistance of stainless steel. It is a fine-grained steel that takes a very sharp edge, and at a hardness of 60-62 HRC, it offers a practical balance of edge retention and sharpenability for everyday kitchen use.

The name "Ginsan" (銀三) literally means "silver three," referring to its Silver #3 designation. Its moderate chromium content makes it far less reactive than carbon steels, so it won't discolor or rust as quickly, while its carbon content keeps the edge keen and responsive on the stones. For home cooks and professionals who want a stainless knife that still feels like a traditional Japanese blade, Ginsan is a common middle ground.

Yoshimi Kato is known for hand-forged Damascus knives with thin geometry and strong cutting performance, working primarily in SG2 and Aogami Super steels from his workshop in Echizen's Takefu Knife Village. He is a certified traditional craftsman (伝統工芸士, earned 2008) and the third-generation blacksmith at Kato Knife Manufacturing, which was established in 1948. His reputation rests on precise heat treatment of premium steels and distinctive Damascus patterns.

Kato also produces knives for the Masakage brand. In recent years he has drawn inspiration from his friend Yu Kurosaki, another Takefu Knife Village smith, and developed newer designs such as the Hyo line. His new gallery and workshop recently opened next to Kurosaki's gallery in Takefu, reflecting the close creative relationship between the two makers.
