The 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 also exist. The inside curve of the weapon could be used to trap an opponent's arm, or to pull an opponent's shield out of the way. 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 khopesh to at least 2500 BC.
