The knife block that is also a sharpening stone: the self-sharpening knife block of the ZWILLING Twin Signature series does the sharpening for you. How? With the ceramic sharpening stones in the slots of the smooth-bladed knives. They are aligned in such a way that you automatically sharpen the bevel every time you push it in and pull it out – so the kitchen knives stay nice and sharp for a long time.

TWIN Signature knives are precision stamped from a single piece of German steel, resulting in lighter weight knives that do not compromise sharpness. 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.To ensure an ideal cutting angle, the laser-controlled edge is incredibly sharp and is honed and hand-finished by the most skilled artisans. The three-rivet handle embedded with the ZWILLING J.A. Henckels logo provides optimum durability.
