Picture of a 1100's becs de corbin. This type of polearm and war hammer that was popular in 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.
