Product Description ------------------- PROFESSIONAL "S" are the classic knives for the professional kitchen. 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. Professional chefs worldwide trust the tradition and quality of these impressive knives. .com ---- Classic three-rivet handles with full tangs distinguish Pro S knives from Henckels's other quality lines, TwinStar, Five Star, and Four Star. That styling, combined with admirably thin blades, results in these knives being a bit heavy in the handle. The blade backs are ground, a touch found only in the finest steak knives. They'll slice a steak into precise bites while contributing class to the table. These knives may be placed in the dishwasher, but hand washing is recommended. --Fred Brack From the Manufacturer The J.A.
