Makhaira

The makhaira was an Ancient Greek bladed weapon and tool, generally a large single-edged knife or sword resembling a modern machete, with depictions becoming common in Greek art from around 530 BCE and especially on red-figure pottery from about 510 BCE onward. Its single cutting edge widened into a convex curve toward the tip, concentrating weight there to give a forceful, slashing cut theoretically capable of cutting through bone, with a curved cutting edge set against a flat back. Despite its frequent appearance in Greek artwork, actual archaeological examples of the makhaira are rare, and the weapon shows regional variation, having been used by both Greek and Persian forces and favored more by cavalry-oriented military cultures than by the phalanx-centered city-states of mainland Greece.
