The Professional "S" 7-Piece Block Set is a classic knife set for the professional kitchen. Combined with JA Henckels signature ice-hardening technique, these stainless steel high carbon 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 while the sturdy bolster provides the right balance and acts as a finger guard.
