or hammer the knife's design relies on sheer momentum to cut efficiently; to chop straight through rather than slicing in a sawing motion. Part of the momentum derives from how hard the user swings the cleaver, and the other part from how heavy the cleaver is. Because of this, the edge of a meat cleaver does not need to be particularly sharp in fact, a knife-sharp edge on a cleaver is undesirable. The

The tough metal and thick blade of a cleaver also make it a suitable tool for crushing with the side of the blade, whereas some hard, thin slicing knives could crack under such repeated stress.

is frequently incorrectly referred to as a "cleaver", due its similar rectangular shape. However Chinese chef knives are much thinner in cross-section and are intended more as general-purpose kitchen knives, and mostly used to slice boneless meats, chop, slice, dice, or mince vegetables, and to flatten garlic bulbs or ginger; while also serving as a spatula to carry prepared ingredients to the wok. For butchering tasks and to prepare boned meats, there is a heavier Chinese "cleaver", used in similar fashion to the Western one.
