The Boomerang is a wooden hunting Weapon. The most recognizable type is the returning boomerang, a kind of throwing stick that, when thrown correctly, travels in a curved path and returns to its point of origin. Other types of boomerang are of the non-returning sort, and indeed, some are not thrown at all but are used in hand-to-hand combat. In Middle-earth boomerang-like weapons were used mainly by the northern and southern Haradrim as well as by some Silvan tribes and Half Trolls.
