A poleaxe or pollaxe is medieval polearm or battle axe with an axe head of the front of the head and a spike or sometimes a hammer head on the back, and a small spear head on top. The weapon is similar in appearance to a halberd, however, the poleaxe has a smaller spear head than the halberd, as well as a smaller axe blade. The smaller axe blade focused the force of impact into a smaller area, making the poleaxe more effective against armor.
