Abstract
The bladed projectile dart disclosed has a bladed head that has a plurality of separable blades that allow for individual replacement. The dart has a hollow shaft that surrounds a draw line which allows for pulling back the projectile when it is mounted in a special slingshot launching device. The draw line is attached at one end to a hub that maintains the blades in formation. The blades are detachable from this hub when the head is lodged in a target. The other end of the blades have a pointed cap that is threadedly mounted to the blade tips. Also described are various launching mechanisms for launching the darts.
