Records show that the implement began to be used about 5,000 years ago, It is still used today in some remote areas of Australia. Like spears and
boomerangs, woomeras were traditionally used only by men. Some woomeras, especially those used in the central and western
Australian
deserts, were multi-purpose tools. Often shaped like long narrow bowls, they could be used for carrying water-soaked vegetable matter (which would not spill and could later be sucked for its moisture) as well as small food items such as little birds or seeds. Many woomeras had a sharp stone cutting edge called a
tula adze attached to the end of the handle with black gum from the
triodia plant. This sharp tool had many uses, such as cutting up game or other food and wood. It is supposed that the woomera could be used as a shield for protection against
spears and boomerangs. The woomera is held in one hand while the other hand places the butt of the spear on the woomera's hook; the hollow curved shape facilitates this alignment without looking. The woomera effectively lengthens the thrower's arm, greatly increasing the velocity of the spear. Correcting for the game animal's lateral dodging is accomplished by tilting the wing-shape woomera during the throw for last-second corrections. The kinetic energy of a spear launched from a woomera has been calculated as four times that of an arrow launched from a
compound bow. Different Aboriginal groups had different shapes and styles of woomera. For example, the woomera of the central desert tend to be very wide and slightly bowl-shaped whereas those of the
Kimberley are flat, long and narrow. ==References==
