Mordhau (weaponry)
In the German school of swordsmanship, Mordhau, alternatively Mordstreich or Mordschlag (in German literally "murder-stroke" or "murder-strike" or "murder-blow"), is a half-sword technique of holding the sword inverted, with both hands gripping the blade, and hitting the opponent with the pommel or crossguard. This technique allows the swordsman to essentially use the sword as a mace or hammer.
