The sickle sword or khopesh
The khopesh is probably the most iconic of the Egyptian weapons. It features a curved, thick blade and measured about two feet long. A khopessh has a thick, crescent shaped blade that is used for slashing. There are several styles of this wicked weapon, and one very well designed style that combines the advantages of both of them. Basically one style has a hook on the end that is used for grabbing people, their weapons or shields and the other variety has a point on the end that can be used for stabbing. The hybrid type has both a point and a hook on it, and this can be used to pull an opponent’s shield down then thrust (stab) the end of the khopesh into their face. There is nothing nice about a Khopesh, it leaves nasty wounds and looks vicious.
