Tomahawk Mod 1.7.10. You can throw any axes that extends Item Axe with this mod as weapon. The damage calculation, enchantment, critical, etc. are all the same as if you hit a mob directly. After hitting a mob, the axe would bounce back and then you can throw it again instantly once you grabbed it.
