5" Utility Knife

Model 31070-131

Ergonomic, German-made knife with a sleek, matte black design

This 5-inch serrated utility knife is ideal for cutting through crusty bread, and thick-skinned fruit, and vegetables. The serrated edge makes cutting through soft-on-the-inside, hard-on-the-outside food effortless, including tomatoes, salami, and bread.

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.
