Aboriginal craft: throwing sticks

Hunting birds with throwing sticks in ancient
Egypt
The
throwing stick or
throwing club is one of the first
weapons used by early humans and cultures all around the world. In essence, it is a short stave or wooden
club thrown as a projectile to hunt small game such as rabbits or waterfowl. In flight, it rotates rapidly, whacking the target with one of the ends, maiming or killing it. The difference between a throwing stick and a
javelin is in their shapes and lengths. A javelin is almost always a straight shaft with either a pointed tip or a spearhead attached to the front end. A throwing stick can be straight like a pointed wooden shaft or curved like the
boomerang, and is much shorter than the javelin. It became obsolete as
slings and
bows became more prevalent. Throwing sticks shaped like returning boomerangs are designed to go straight to a target. Their surfaces are not shaped unevenly like
airfoils, but are symmetrical on both sides, and do not exhibit curved flight.
