<p>A darts enabling an increase in the durability of a darts tip without using a hard material and the easy extraction thereof from a board and preventing the board from being damaged and the tip of the darts. Four grooves (18) are formed in the surface of the tip (10) along the longitudinal direction from its tip (12) up to its other end (14), and the cross section thereof is formed in a shape other than circular shapes. The tip (12) is fitted to a board hole, and the other end (14) is formed detachable from the end of a barrel not shown. Since the cross section of the contact portion of the tip with the board is formed in a shape other than circular shapes by forming the grooves (18) therein, a load applied to one point is reduced and the durability of the tip (10) can be increased. Since the durability of the tip (10) is increased depending on the shape thereof, the hard material must not be used for the tip, the load on the darts board is reduced, and the durability of the board can be increased. Furthermore, since the contact area of the tip with the board is reduced, the darts tip can be easily extracted from the board.</p> |
