A bec de corbin (, ) is a type of polearm and war hammer that was popular in late medieval Europe. The name is Old French for "raven's beak". Similar to the Lucerne hammer, it consists of a modified hammer's head and spike mounted atop a long pole. Unlike the Lucerne hammer, the bec de corbin was used primarily with the "beak" or fluke to attack instead of the hammer head. The hammer face balancing the beak was often blunt instead of the multi-pronged Lucerne, and the beak tended to be stouter; better designed for tearing into plate armor, mail, or gambeson. Nonetheless, some becs-de-corbin also had a multi-pronged hammer.
