ZWILLING Tradition knives are precision stamped from a single piece of German steel, resulting in lighter-weight knives that do not compromise sharpness or strength. The knives are made of proprietary special formula steel that has been perfected for over 280 years. Combined with ZWILLING's signature ice-hardening technique, these FRIODUR blades are harder and sharper, they will not stain or chip and they retain their sharpness longer. To ensure an ideal cutting angle, the laser-controlled edge is incredibly sharp and is honed and hand-finished by the most skilled artisans. The three-rivet handle embedded with the ZWILLING J.A. Henckels logo provides optimum durability. Plus enjoy a bonus 8 Pc Steak Knife Set.
