ZWILLING
**** Four Star
7-inch, Santoku
This 7-inch hollow edge santoku is perfect for all kitchen tasks. Santoku - Japanese for "three virtues" - excels at three cutting techniques: expertly mince garlic, slice cucumber, and dice onions with this Asian all-rounder. The hollow edge features a blade that has small indentations, known as grantons, that prevent food from sticking while cutting.
Four Star knives are made of proprietary special formula steel that has been perfected for almost 300 years. Combined with ZWILLING’s signature ice-hardening technique, these FRIODUR blades are harder, sharper, they will not stain or chip, and they retain their sharpness longer. Precision forged from a single piece of steel, the SIGMAFORGE knives have an exceptionally sturdy, balanced, and flexible blade.
