A type of sword that has a blade length of ~27"-36". It has a straight double-edged blade and weighs around 2-3.5 pounds if made out of decent high carbon steel. It showed up historically after people had good enough steel to extend the blade length of short swords. A long sword differs from a broadsword in that it has a double-edged blade, and a broadsword only has a single-edged blade. One step below a bastard sword.
