Tsunehisa is a company that works with a variety of blacksmiths. The Migaki Ginsan knives are produced in Tosa, Japan.

Tsunehisa knives use high quality steels at a very reasonable price and nice fit and finish.

Ginsan (Gin3 or Silver #3) is a stainless carbon steel, with 14% added Chromium. Retaining the character of Japanese carbon steel, with similar hardness of Shirogami #2, Ginsan is stainless. It's edge retention is only slightly inferior to Shirogami #2, but the fact that it combines ease of sharpening, carbon steel character as well being stainless makes it a great choice for those who wish to have a Japanese carbon steel knife that is easy to maintain.
