J.A. Henckels Twin Four Star 8-Inch High Carbon Stainless-Steel Chef’s Knife

Four Star knives are precision forged from a single piece of exclusive-formula, high carbon, no stain steel under the all-new Sigmaforge standard. As a result, Four Star blades have improved quality consistency, lasting sharpness, and perfect geometry. Sigmaforge one-piece construction also provides high precision and improved stability of the blade and steel structure, thus improving cutting-edge retention for lasting sharpness.

In addition, Four Star knives use J.A. Henckels’ Friodur ice hardening for corrosion resistance, a process that also contributes to cutting-edge retention.
