Nigara VG10 Damascus Tsuchime Santoku 175mm

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, with a gently curved edge that lets you rock and slide through cuts as well as chop. Tojiro's guide to Western knife shapes gives 150 to 210mm as the household size for a gyuto and up to 360mm for professional use. The extra length and pointed tip give you reach and versatility, from proteins to large produce.

Tojiro's guide to Japanese knife shapes gives 165 to 170mm as the household size for a santoku, which has 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.

Match the shape to your stroke. Rock chopping keeps the tip on the board and rolls the curved belly through the food, so a gyuto or a Western chef's knife suits it, and Japanese knives rock fine as long as you rock gently.

Up-and-down chopping, the Chinese style, wants a straight run of edge, so a nakiri, usuba, santoku or bunka suits it better; a curved edge chopped straight down easily leaves pieces joined. Neither shape is better; it depends on how you cut.

A Japanese dictionary explains the name of the santoku (三徳包丁) as coming from the three things it handles: meat, fish and vegetables. The same dictionary entry points from the santoku to the bunka (文化包丁), treating the two as one knife.

One Japanese knife maker guide distinguishes the two by the tip. It says that in the Showa era the bunka was made with its tip cut at an angle, and the santoku came after it by rounding that tip.

Yes, it can, though it rusts less readily. VG10 (V金10号) is a stainless steel, and stainless strictly means a steel that rusts less, not one that never rusts.

Takefu, which makes VG10, lists 15% chromium, above the 10.5% that defines stainless steel, and describes its corrosion resistance as excellent. Dry the knife after washing.

Takefu, the steelmaker behind VG10, gives HRC 60 or more as a standard value. The hardness of a finished knife depends on its maker.

Takefu says the steel's 15% chromium, 1% molybdenum and 1.55% cobalt give it high hardness and a long-lasting edge, and that it is easy to sharpen.

The Nigara family line began in 1803, when the family served the Tsugaru domain as gunsmiths. For generations afterwards it made Japanese swords.

After the Second World War, the forge turned to blades for everyday life, including farm tools and kitchen knives.

Go Yoshizawa, president of Nigara Hamono Forge, leads it today and signs as the eighth generation of the Nigara family line.

The company is Nigara Hamono Forge (二唐刃物鍛造所), in Kanazoku-machi, Hirosaki, Aomori.

We think so. Nigara's own company page says its family line began in 1803 as gunsmiths retained by the Tsugaru domain and made Japanese swords for generations, before turning to farm tools and kitchen knives after the Second World War.

We have visited Nigara several times, once for a few days of hands-on training with them, and we list its knives in steels such as SG2, Blue 2, Ginsan and VG10.
