About This Item
Four Star knives are made of proprietary special formula steel that has been perfected for almost 300 years. Combined with ZWILLING’s signature icehardening 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.
