Santoku Knives - Superior Japanese-German fusion cutlery, the Zwilling Morimoto Red Hollow-Edge Santoku Knife is designed in collaboration with chef Masaharu Morimoto, the world's most recognized Japanese chef and Iron Chef on "Iron Chef America." Santoku means "three virtues" which often refers to the santoku knife's exceptional performance in three styles of kitchen prep: chopping, slicing and mincing. The hollow-ground edge ensures smooth stick-resistance and the Zwilling special formula German steel delivers long-life durability. The exclusive Sigmaforge precision forging creates an exceptionally hard blade that resists stains, chips and rust. Friodur ice-hardened to a 57 Rockwell Hardness, the santoku knife blade starts sharper and stays sharper longer. Honbazuke-style hand sharpening to 9.5-12 degrees produces scalpel-sharp edges. Engineered with glass fiber enhanced plastic for added strength, the handle's red spacers create the specific and unique Miyabi signature. 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.
