Boomerangs can return and axes can chop. What if you just used an axe as a boomerang. Once upon a time there existed a weapon in Terraria known as a possessed hatchet. Basically a very nice homing axe that flew back after hitting your target. A boomerang axe. All these years I falsely assumed that it was just an interesting fantasy weapon, but boy was I wrong.

Some axes, if thrown properly, function like boomerangs. It's one of those skills that would be really awesome to learn, but with a bit too much risk to get into.
