Outside of a niche application of flushing out small game animals, it is a joke weapon that is rarely, if ever, offered for sale in serious hunting shops. Anthropologists working in Australia did find an old skeleton with skull and rib fractures they thought were made by a boomerang, having ruled out the didgeridoo and the digging stick for lack of a sharp edge. This led them to think that the boomerang could have been used as a weapon of murder and war. An alternative theory is that the poor person who once owned this skeleton simply had the habit of throwing his boomerang and then forgetting that he threw it. And so he just stood around gawking until it flew back and hit him.
