A Hand and a half sword, colloquially known as a "bastard sword", was a sword with an extended grip and sometimes pommel so that it could be used with either one or two hands. Although these swords may not provide a full two-hand grip, they allowed its wielders to hold a shield or parrying dagger in their off hand, or to use it as a two-handed sword for a more powerful blow. These should not be confused with a longsword, two-handed sword, or Zweihänder, which were always intended to be used with two hands.
