The Lucerne hammer is a type of polearm which was popular in Switzerland during the 15th to 17th centuries. It was a combination of the bec de corbin with the blunt war hammer. The name comes from a discovery of many of these weapons in Lucerne, Switzerland. The 'hammer' was actually a three- to four-pronged head mounted atop a 2m-long (7 foot) polearm stick. It bore a long spike on its reverse, and an even longer spike extending from the very top. It proved effective at puncturing or smashing armor, and much like a man catcher was used for dismounting riders.
