Four Star knives are made of proprietary special formula steel that has been perfected for almost 300 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. Precision forged from a single piece of steel, the SIGMAFORGE knives have an exceptionally sturdy, balanced, and flexible blade.
