Global Sai Santoku knives are perfect for home or professional chefs. Like the Chef knife, the Santoku is ideal for chopping, dicing, cutting, slicing, and carving. The Sai handle features a more ergonomic shape with a hollowed out place for your fingers. The blade material consists of a central core material of substantial hardness to keep an extremely hard edge surrounded by layers of softer, corrosion resistant stainless steel. The exterior steel is hammered resulting in a beautiful finish that also keeps food from sticking to the blade. The blades are sharpened to a 12.5 degree angle for amazing performance
