While it may be difficult to use a whole swordfish as a weapon, people have used the swordfish sword or bill effectively as a weapon. See a recent academic article about penetrating chest injuries using a swordfish sword (http://bit.ly/swordfishweapon). Also, in 2010, a couple of Australian men had a drunken fight in which one used a swordfish bill as a weapon (http://bit.ly/swordfishbillweapon).
