About this item
Product details
FOUR STAR is the top-selling knife series of ZWILLING J.A. Henckels worldwide. Honed and hand-finished by the most skilled artisans, this celebrated collection is the model of safety, ergonomics, and comfort.

The knives are made of proprietary special formula steel that has been perfected over the 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.

Nice all-around kitchen knife
Beautiful, versatile knife. Well balanced. Unfortunately, I snapped the blade of my 40 plus year old knife and needed to replace it.

Beware of sharpness
Knife is well balanced and very sharp. Husband has cut himself twice.
