CLEAVER: A heavy, large core or flake tool of the Paleolithic period, typically having a wide, straight cutting edge at one end, like a modern axhead. Technologically it is related to the hand ax, and is often found as a component of Acheulian (especially Upper Acheulian) hand-ax industries. The sharp transverse cutting edge was almost always notched by use but never sharpened. Along with bifacial tools, it was one of the main instruments of Homo erectus. It is found mainly in Africa, where much of the flake surface is left unretouched. The axlike knife was used from the Middle Pleistocene era to cut through animal bone and meat.
