"Gingami I is a steel that was made by Hitachi. When we first began making knives (1981), Gin I was the best available production knife steel. (and the most excpensive). ATS-34 was available, but still difficult to get and use in production. It's a very nice blend of alloys and produces a tough steel with very good edge holding and very good corrosion resistance. We've recently considered using the steel in low cost models. Hitachi is no longer making the steel at this time." [2]
