Spears and pole weapons

Spears were one of the most common personal weapons used in the Stone Age, and they remained in use as important military and hunting implements until the advent of firearms. They may be seen as the ancestor of such military weapons as the lance, the pilum, the halberd, the naginata, the glaive, the bill, and the pike. One of the earliest weapons fashioned by human beings and their ancestors, the spear is still used for hunting and fishing. The most common design for hunting or combat spears since ancient times has incorporated a metal spearhead shaped like a barbed triangle, lozenge or leaf.
