A pole weapon or polearm is a close combat
weapon in which the main fighting part of the weapon is placed on the end of a long shaft, typically of
wood, thereby extending the user's effective range.
Spears,
glaives,
pollaxes and
bardiches are all varieties of polearm. The idea of attaching a weapon onto a long shaft is an old one indeed, as the first spears date back to the
Stone Age. The purpose of using pole weapons is either to extend reach or to increase
angular momentum—and thus striking power—when the weapon is swung.
