Description
The Zwilling Pro chef knife is Sigmaforge-stamped from a single piece of Zwilling’s special formula stainless steel. The ergonomic curved handle and ice-hardened Friodur blade deliver enduring sharpness for daily professional use.

Rhythm of the Line
Brunoise carrots and julienne peppers flow from the blade with metronomic consistency.
The curved handle nestles into your palm during hours of continuous prep without fatigue.
Forged in One Strike
Zwilling’s Sigmaforge process stamps each blade from a single steel billet, eliminating weak points found in welded constructions.
Friodur ice-hardening at −60°C refines the grain for a denser, more resilient edge.

Knife Care & Maintenance
Keep your blade performing at its best. Rinse and dry after each use to prevent corrosion. Apply a thin coat of mineral oil to the blade periodically. Sharpen with a whetstone or honing rod at a consistent angle. Store in a sheath, knife roll, or magnetic strip — never loose in a drawer. For carbon and Damascus steel, wipe after contact with acidic foods. For folding knives, clean the pivot area and apply a drop of lubricant to ensure smooth deployment.
