The Global Hollow Edge Santoku Knife is the multipurpose workhorse of the kitchen. Perfect for mincing, cutting, chopping, slicing and prep work. The scalloped grooves on the sides of the blade edge helps with reducing friction and sticking of foods. Global Knives have two most innovative features, the edge and the way they are balanced. The most important feature of any knife is its edge. The blade is made from one of the finest steels, Cromova 18 stainless steel. This special steel is ice-tempered and hardened to a Rockwell Hardness of 56-58°, which remains razor sharp longer than any other steel and resists rust, stains and corrosion. The blade edge is ground on both sides of the blade like western style blades; however the edge is ground to a straight point rather than a beveled edge which results in a razor sharp edge that will stay sharper longer. To balance the blade, all Global knives have a unique hollow handle filled with the right amount of sand to create the perfect balance. Global knives are truly unique. Made in Japan with a lifetime warranty.
