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.
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. The Khopesh went out of use around 1300 BC. However, in the 196 BC Rosetta Stone it is referenced as the "sword" determinative in a hieroglyphic block, with the spelled letters of kh, p, and sh to say:
Although some examples have clearly sharpened edges, many examples have dull edges that apparently were never intended to be sharp. It may therefore be possible that some khopeshes found in high status graves were ceremonial variants.
