Khopesh is an Egyptian sickle-sword that evolved from battle axes.
A typical khopesh is 50–60 cm (20–24 inches) in length, though smaller examples do also exist. The blunted edge of the weapon's tip also served as an effective bludgeon, as well as a hook. These weapons changed from bronze to iron in the New Kingdom period.The earliest known depiction of a khopesh is from the Stele of Vultures, depicting King Eannatum of Lagash wielding the weapon; this would date the kopesh to at least 2500 BC.
The blade is only sharpened on the outside portion of the curved end. The khopesh evolved from the epsilon or similar crescent shaped axes that were used in warfare. Note, however, that the khopesh is not an axe. Unlike an axe, the khopesh did not make push-cuts, but rather slashes, like a sabre. The khopesh went out of use around 1300 BC. Various pharaohs are depicted with a khopesh, and some have been found in royal graves, such as the two examples found with Tutankhamun. Although some examples are clearly sharpened, many examples have dull edges which apparently were never intended to be sharp. It may therefore be possible that some khopeshs found in high status graves were ceremonial variants.
