Description
The Zwilling Four Star kitchen knife is precision-forged from a single piece of Zwilling's special formula stainless steel, then ice-hardened using the proprietary Friodur process for exceptional sharpness, flexibility, and corrosion resistance. The 20cm blade features a laser-controlled edge for immediate cutting performance.

**Solingen Heritage**
Forged in Solingen, Germany's City of Blades, each Four Star blade undergoes the Friodur ice-hardening process — cooled to -70°C to refine the steel's molecular structure. The result is a blade that stays sharper longer while resisting corrosion and flexing.

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.
