"Gin-san steel" is a traditional stainless steel that has been widely used in the world of Japanese knives for a long time. It is a steel material trusted by chefs even for Japanese knives that require sharpness. Hitachi Metals, which manufactures Yasuki steel such as White Steel and Blue Steel, created Silver Paper Steel as a rust-resistant stainless steel. Gin-san steel is made by increasing the carbon content and raising the hardness of this Silver Paper Steel. It is a long-lasting steel among stainless steels, making it suitable for those who use knives for extended periods.
