Zwilling J.A. Henckels Four Star knives are crafted from high-carbon stainless steel known as X50CRMOV15, a premium alloy also used in renowned lines like the Wusthof Classic Ikon Series. While the base formula is similar, each manufacturer employs unique hardening, shaping, and sharpening techniques. Zwilling’s proprietary Friodur® ice-hardening process enhances the steel’s hardness, toughness, and corrosion resistance, resulting in blades that deliver excellent sharpness, edge retention, and stain resistance. These knives are highly durable yet easy to maintain, making them ideal for both everyday and demanding kitchen tasks. For optimal longevity and performance, it’s best to hand wash and promptly dry the knives, as dishwashers may degrade the cutting edge. Regular honing helps preserve sharpness, while periodic sharpening ensures precise and reliable cutting over the years.
