ABSTRACT:
A novel dart is equipped with a dart point contraction system which allows the dart point to contract into the body or barrel of the dart as when the dart point impacts wire, or staples and the like which surmount boundaries of denominated regions of a dart board. The dart body defines a cylindrical cavity into which the downstream end of the dart point can reciprocatingly travel since it also is cylindrical and comes to rest against the dart body at the end of its travel. It is as a result of kinetic energy of flight that even though the dart point may have impacted a boundary wire or even a denominated region of the dart board, dart "bounce-out" is inhibited by the momentum of dart point upstream end travelling into the dart body housing. Because of a tapered furrel in the front portion of the dart body, the whole dart point system furrel and point may be simply removed as by (strongly) pulling or to be replaced most conveniently with a simple extraction tool.
