Boomerang

The boomerang is a throwing weapon whose name comes from an Aboriginal Australian language of the Sydney region. The oldest surviving Aboriginal boomerang, held today in the South Australian Museum, was recovered from a peat bog and dates to roughly 10,000 BC. Returning boomerangs, shaped with airfoil sections that spin about an axis perpendicular to their flight path, were developed by Aboriginal Australians, while related non-returning throwing sticks were used independently by ancient Egyptians, Native Americans and various European peoples. As a hunting weapon a heavier non-returning boomerang of about two kilograms could inflict a fatal wound on a large animal from as far as one hundred meters, and hunters sometimes threw a boomerang to mimic a hawk in flight, panicking flocks of birds down into nets or toward waiting hunters armed with clubs.
