The perfect Gyuto Aogami 2 S/S Clad ISW-16 from Ittetsu knife with a 18 cm blade for any task in the kitchen. Octagonal handle is made of walnut. The bolster is made of Macassar ebony. The blade is made of Aogami #2 with stainless steel clad, Nashiji finnish. This is very similar to white paper steel but with tungsten and chromium added to it which helps with edge retention and slows down rusting. The steel has then been hardened to 62-63 Rockwell and wrapped in stainless steel to further ease maintenance. This knife cannot be washed in the dishwasher. Hand wash with warm water and towel dry. Japanese kitchen knives have a very hard but thin blade. Japanese knives are not allowed to cut bones and meat with bones, coconuts and other nuts, and other hard foods. Ittetsu knives due to handmade may differ slightly from those shown in the photos and sizes. Echizen city, Japan. Weight 345 gr.
