KitchenAid Cooks Stamped Santoku Knife (5-Inch) Each package contains one Santoku knife. The hand wash only knife's high carbon stainless steel blade is fixed to the handle with a stamped triple rivet for strength and reliability. The kullens on the blade limit food from sticking and tearing while cutting and the blade can function as a chef knife, slicer and utility knife. The high carbon steel blade holds an edge longer than conventional stainless steel blades and is easy to sharpen. The contoured handle and blade are ideally weighted and balanced for perfect control.
