Another name for the longsword, so called because the style in which it is used is a 'bastard' hybrid of one and two handed fighting. The weapon is light enough that it can be used in one hand, but the hilt is long enough that a second hand can be added for additional power. Also called a hand-and-a-half sword
Somewhere between the short sword and the greatsword lies the bastard sword.
