Utility Knives - A go-to food prep knife for cleanly slicing, chopping and mincing produce and meats, the Morimoto Edition Zwilling Miyabi Fusion Utility Knife was developed in collaboration with world-renown chef Masaharu Morimoto. The Miyabi Fusion kitchen knife offers optimum sharpness, balance and comfort and its rounded spine and blade heel are gentler on the fingers and hands. A floral Damascus pattern and Katana edge add unique distinction to the Japanese thin blade. The CMV60 (VG-10) Japanese stainless "super steel" core blade features 64 outer layers (32 per side) of stainless-steel for superior edge retention. The Cryodur ice-hardened and 59-61 Rockwell Hardness utility knife starts sharper and stays sharper longer. Honbazuke-style hand sharpening to 9.5-12 degrees produces scalpel-sharp edges. Engineered of black resin-Duracon and striking red accents, the triple-riveted full tang handle is hygienic and precisely weight balanced for better control. In 1731 German knife maker Peter Henckels registered his "TWIN" trademark, which helped his company flourish into one of the world's most exclusive, best-performing kitchen cutlery producers. Following the company's nearly 300 years of tradition and innovative success, Zwilling J.A. Henckels Japan continues to ensure superior quality cutlery for professional and home gourmets worldwide.
