These beautiful knives use a stainless steel relatively new to the market called ZA-18, which was developed by Aichi Steel Co. The composition of the steel uses the following: carbon 1.20, chromium 18.0, molybdenum 1.5, and cobalt 1.80 for added hardness, toughness, and corrosion resistance. It's an excellent kitchen knife steel.
