Santoku, gyuto, bunka, nakiri — and which one is handed

Four names for double-bevel Japanese knives, two of which are the same knife. The differences that matter are the tip, the profile, and whether the blade is handed at all.

Two of these are the same knife

Wikipedia is unusually direct about the first pair: the santoku bōchō and the bunka bōchō are the same general-purpose knife, and the difference is the tip. A santoku has a sheep’s-foot tip, curving down to a point at close to 60 degrees; a bunka has a k-tip, a reverse tanto. The gyuto is the Japanese take on the Western chef’s knife, with more curve along the edge, which is what lets it rock rather than chop.

The pair that is not interchangeable

The one that is not interchangeable is the vegetable knife. A nakiri and an usuba look alike — flat-edged, rectangular — but Wikipedia puts them on opposite sides of the divide this site keeps returning to: the nakiri is sharpened ryōba, from both sides, and is described as a knife for home use, while the usuba is kataba, ground on one side. So a nakiri suits either hand and an usuba does not. If you are choosing a vegetable knife and the listing says only “Japanese vegetable knife”, that is the fact it has left out.

Why they cut differently from Western knives

Two more things follow from the same article. Traditional Japanese knives were single-bevel — kataba — and that remains dominant in professional Japanese kitchens; the double-bevel shapes above are the ones that developed for general and home use. And Japanese double bevels are usually thinner right behind the edge than Western ones, which is why they cut the way they do and also why they are less tolerant of bones and frozen food.

Where to look

The name on the listing tells you the shape and almost nothing else. Two things decide whether the knife suits you and both are often missing: the grind — single or double bevel, which is the difference between a knife that works in either hand and one that does not — and the steel, carbon or stainless, which is the difference between a blade that wants drying after every use and one that does not. The two guides below cover those.

There is no shop link on this page. Which shape suits you depends on how you cut, which is not something a page can decide for you — and the shape is the part listings usually do state correctly. It is the grind and the steel that go unmentioned.
