ZWILLING Professional "S" knives are the classic knives for the professional kitchen. A solid steel, seamless manufacturing and three rivet design with full tang delivers optimum balance and the safe handling. The knives are honed and hand-finished by the most skilled artisans. The laser controlled edge is incredibly sharp. The knives are made of proprietary special formula German steel that has been perfected over the years. Combined with ZWILLING's FRIODUR ice-hardening technique, the result is a harder, sharper blade that will not stain or chip and remains sharp longer. Each knife is precision forged from a single piece of steel using ZWILLING's SIGMAFORGE process. The result is an exceptionally sturdy, balanced, and flexible blade. The bolster provides the right balance and acts as a finger guard. The paring knife is a small knife with a strong blade and center tip. It is ideal for cleaning, peeling and cutting small fruits and vegetables.
