"Gin-san steel" is a traditional stainless steel that has long been used in the world of Japanese knives and is trusted by chefs for its sharpness. Hitachi Metals, which manufactures Yasuki steel such as Shiro-gami and Ao-gami, created Gin-gami steel as a rust-resistant stainless steel. Gin-san steel is made by increasing the carbon content and hardness of Gin-gami steel. It is a steel that holds its edge for a long time among stainless steels, making it suitable for those who use knives for extended periods.
