Precision forged using Zwilling's Sigmaforge process, which incorporates the Friodur ice-hardening technique to produce a corrosion-resistant blade that is exceptionally hard yet flexible. High-carbon stainless-steel blades are hand-sharpened and polished by master craftsmen to create a long-lasting, razor-sharp edge. Precise lasers are used to ensure each blade's edge is at the ideal cutting angle for maximum sharpness. Made in Germany by Zwilling J.A. Henckels, founded in 1731.
