## Description

PRODUCT DESCRIPTION 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. desertcart.COM With a flexible blade that bends around big bones and joints, this knife will fillet a trout but works best with poultry and meats. Classic three-rivet handles distinguish Pro S from Henckels's other quality lines. Pro S handles are heavier and its knives less weight-forward. Handles are also smaller, a feature those with small hands may appreciate. The steel used in the Pro S line is identical to that of the Five and Four Star lines. While this boning knife is dishwasher-safe, hand washing is recommended. --Fred Brack From the Manufacturer The J.A.
