Forked Sword

The Forked Sword (as well as the Spatha, which looks the same) has an angular, strangely-shaped blade. If the weapon were a real world weapon, the large front part of the blade would be used for hacking and chopping, the longer portion of the blade at the rear for thrusting and prodding attacks, and the long opening between the two would be used to trap and possibly break an opponent's blade.
