In cooking, a chef's knife, also known as a cook's knife, is a cutting tool used in food preparation. The chef's knife was originally designed primarily to slice and disjoint large cuts of beef. Today it is the primary general-utility knife for most western cooks. A Japanese gyuto (牛刀 ぎゅうとう）, gyūtō), literally meaning 'beef knife', is the Japanese version of a French (or Western) chef's knife. They were originally, and sometimes still called "yo-boucho" 洋包丁 meaning "Western Chefs Knife". The Chinese chef's knife is completely different and resembles a cleaver.
