Warhammer
A warhammer consists of a handle and a head made of wood or metal. The length of the handle may vary, the longest being roughly equivalent to that of a halberd (5 to 6 feet or 1.5 to 1.8 meters), and the shortest about the same as that of a mace (2 to 3 feet or 60 to 90 centimeters).
Warhammers, especially when mounted on a pole, could in some cases transmit their impact through helmets and cause concussions. War hammers often had a spike on one side of the head, making them more versatile weapons. The spike end could be used for grappling the target's armor, reins, or shield, but could not penetrate the surface of plate armor. Against mounted opponents, the weapon could also be directed at the legs of a horse, toppling the armored foe to the ground where they could be more easily attacked.
