Named for the sacred sword carried by Japan's Samurai warriors, Calphalon Katana Series cutlery has its roots in a centuries-old tradition of superior cutlery craftsmanship. Like the awe-inspiring swords wielded by the Samurai, Calphalon Katana Series cutlery is crafted using a time-honored layering process that creates a Damascus style blade, clad with 33 stainless steel layers. This unique series of cutlery uses VG Japanese steel, which provides exceptional sharpness and ultimate edge retention. These knives also feature a patented integrated bolster design and an ergonomically designed poly-resign handle. Combining features of a chef's knife and a cleaver, the Santoku is an all-purpose knife that's ideal for cutting meat, fish and vegetables. The word santoku means three good things ¿ a reference to the three cutting tasks it performs so well: slicing, dicing and mincing. The kullens along the edge help reduce friction, which prevents food from sticking.
