Also known as a Cook's Knife, the Chef's Knife is an All-Purpose Knife used for slicing, chopping, dicing, mincing and many other functions. The blade is curved to allow the cook to rock the knife on the cutting board for a more precise cut. The Chef's Knife is most commonly available between 6 and 12 inches, though 8 inches is the most common size. Most chefs recommend using the largest Chef's Knife that is comfortable in the cook's hands. Larger knives can cut more and are more versatile, but can be more difficult to handle.
