As with spears and boomerangs, woomera were traditionally only used 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 could later be sucked for its moisture, but wouldn't spill) as well as small food items such as little lizards or seeds. Many woomeras had a sharp stone cutting edge attached to the end of the handle with black gum from the spinifex plant. This sharp tool had many uses – and was commonly used for cutting up game or other food, cutting wood, and so on.
