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, sharper, they will NOT STAIN or chip and they retain their sharpness longer. Honed and hand-finished by the most skilled artisans, the knives' laser-controlled edge is incredibly sharp. The sturdy bolster provides the right balance and acts as a finger guard. Precision-forged from a single piece of solid steel, these three rivet handle knives deliver optimum balance and safe handling.
