Chacing staff

A chacing staff is a kind of polearm that was used in the Middle Ages of Europe. It consisted of an iron-shod staff some 10–12 feet long, with a spike on the butt end and a metal head at the other. The head was made of a large, flat 'blade' which had a few small protrusions coming off of the top and back. It resembled an early halberd or bill.
