The Scythe as a weapon.

[kronckew]

The khopesh appears to have evolved from the Epsilon Axe popular in the area at the time. Not from the sickle or scythe. Being ductile bronze, it (and the epsilon) was not used for chopping, but for slicing draw and push cuts. There was a 'chopping' version of the axe, the duckbill, that was designed for chopping, and the egyptian bronze penetrative axe was also.
