The Zwilling Professional 'S' 6pc Block Set is a versatile and high-quality knife set that is perfect for any kitchen. The knives are precision forged from a single piece of no-stain special formula steel, ensuring durability and excellent cutting performance. Thanks to the FRIODUR ice-hardening process, the blades are exceptionally sharp and will not stain or chip, making them perfect for long-term use. The 55-57 HRC Rockwell blades provide extreme hardness and corrosion-resistance, ensuring that these knives will stand the test of time. While the set is dishwasher safe, it is recommended to hand wash them to prevent any potential damage to the handles caused by high heat. With its sleek design and superior craftsmanship, the Zwilling Professional 'S' 6pc Block Set is a must-have for any cooking enthusiast or professional chef.
