A. Boomerangs (or throwsticks) for Hunting.

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.

B. Returning Boomerangs: They are throwing sticks that travel in an elliptical path and return to their point of origin when thrown correctly.
