A new study into the multipurpose uses of boomerangs has highlighted the hardwood objects were used to shape the edges of stone tools used by Australian Indigenous communities. The research demonstrated how boomerangs could function as lithic (or stone) tool retouchers by investigating the use-wear generated on the boomerangs’ surfaces during retouching activities. It was found that these use-wear impacts on boomerangs comparable to those observed on Paleolithic bone retouching tools, which date back to more than 200,000 years ago.
