Blade throwers are large Horde towers that hurls sawblades. Several of these siege weapons can be seen along the Path of Glory leading from the Dark Portal through Hellfire Peninsula in Outland. The expedition Thrallmar uses these in their fight against the fel orcs of Hellfire Citadel, and once used them against the Alliance in Honor Hold. In  , Horde Blade Throwers are burned to prevent them being used on the Alliance.
In Wrath of the Lich King, blade throwers are also used by the forces of the Kor'kron Vanguard. Some can also be seen ruined at Thrym's End, but they may be meant to be something else, as the spiked parts seem attached to the walls.
