The Global Sai 8 inch chef's knife has improved their classic 8-inch chef's knife design in several ways. The blade is super sharp and long-lasting because it's made with a new 3-layer construction that features a core of Cromova 18 stainless steel with an extra layer of stainless steel clad to each side. The sides of the blade are also hand hammered, giving it a great look and helping prevent food from sticking to the sides of the blade. This Sai chef's knife from Global comes with a lifetime warranty and is made in Japan.
