The Bronze Age khopesh was a sickle-shaped curved sword that evolved from earlier forms of crescent-shaped Mesopotamian battle axes. By the start of the New Kingdom of Egypt period (ca. 16th BCE), it had become one of the most popular ancient Egyptian military weapons.
The most striking feature of this one-handed infantry sword was its hook-shaped blade that tapered to the outer edge, making it a slashing and hideously powerful tool of war in close combat. Although primarily designed as a slashing weapon, it could also be used for thrusting or to knock down the opponent, disarm them, or hook their shield. The high effectiveness and versatility of this sword, which was quite advanced for its time, most likely contributed to the long-lasting sovereignty and stability of the Egyptian Empire.
Numerous depictions of pharaohs wielding a sickle-sword in ancient Egyptian art, as well as well-preserved surviving examples found in royal tombs (for example, in the tomb of Tutankhamen, 14th century BC) suggest that this iconic weapon also had a ceremonial value and was a symbol of high status and prestige.
Finally, the Khopesh fell out of use around 1300-1200 BCE. C., gradually replaced by more traditional straight swords.
