Some versions have one end that is 7.6 cm (3.0 in) wide and possessing a hollow, curved cross-section not unlike an airfoil, while the other is more pointed and has a hook.
Some woomera were traditionally decorated with incised or painted designs that indicated belonging to a particular linguistic group that it may be returned to if found abandoned.
[9] 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[10] attached to the end of the handle with black gum from the triodia plant.
[11] 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.
