This is a hunting boomerang made by Victor Poulin of BoomerangsByVic. Vic has made many different designs over the years for everyday throwers to the most experienced of throwers. This particular design would be excellent for hunting. Although it is not common for returning boomerangs to be used for hunting it does not mean it can not be done.
The main reason is how hard it would be to actually hit your target. Australian "hunting" boomerangs did not actually return at all. It was basically a stick with a slight curve on one end. It would be thrown side arm horizontally to fly out somewhat straight.
Feel free to ask questions below and I will be happy to answer. Have a great life everyone.
