A. Boomerangs (or throwsticks) for Hunting.
B. Returning Boomerangs:
They are throwing sticks that travel in an
elliptical path and return to their point of
origin when thrown correctly.
A returning boomerang has uneven arms or
wings, so that the spinning is lopsided to
curve the path
They are used for sport and recreation.
They fly in a nearly straight path when
thrown horizontally and are heavy enough
to take down a kangaroo on impact to the
legs or knees. For hunting emu, the
throwstick is aimed toward the bird's neck,
in an attempt to break it.
