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. This knife is the most commonly used knife in the kitchen. The blade of the Chef knife is designed to handle a wide range of tasks. It is gently curved from tip to heel allowing you to use a gentle rocking motion as you cut.
