Is 8 inches standard for a chef's knife?
Chef's knife
A chef's knife generally has a blade eight inches (20 centimeters) in length and 11⁄2 inches (3.8cm) in width, although individual models range from 6 to 14 inches (15 to 36 centimetres) in length. There are two common types of blade shape in western chef's knives, French and German. German-style knives are more deeply and continuously curved along the whole cutting edge; the French style has an edge that is straighter until the end and then curves up to the tip. Neither style is inherently superior; personal preference will dictate the choice.
