Zwilling Twin Gourmet knives are precision stamped from a single piece of Zwilling exclusive high-carbon stainless steel formula for excellent cutting performance and sturdiness. The laser controlled edge is sharp, and stays sharper longer. The Friodur ice hardening process is corrosion resistant and contributes to cutting-edge retention. Features a traditional triple-riveted handle design for strength and durability. The black Novodur handles are smooth and comfortable to use, while the fully visible tang is bonded to the handle, providing proper balance.
