"A boomerang is a thrown tool, typically constructed as a flat airfoil, that is designed to spin about an axis perpendicular to the direction of its flight. A returning boomerang is designed to return to the thrower. It is well known as a weapon used by Indigenous Australians for hunting.
Boomerangs have been historically used for hunting, as well as sport and entertainment. They are commonly thought of as an Australian icon, and come in various shapes and sizes." - (en.wikipedia.org 08.09.2019)
