Abstract: Over the years, batons have not changed much in size or shape. The ends of the baton are still rubber with a steel shaft in between. Little has been done to prevent the baton from slipping out of the twirler's fingers due to moisture or to keep the baton from rolling away when dropped. The primary essence of this patent is to reduce rolling action and bounce when dropped as well as slippage due moisture. This patent introduces a newly designed ball and tip that is in the general shape of a tetrahedron that transitions into a frustum shape that connects the ends to the shaft. The functional shape of baton ends appears to be an equilateral triangle when viewed looking down the axis of the baton shaft. The effect of this design is that three flat surfaces on each end of the baton are oriented so that the flats are in the same plane with each other, which creates resistance to rolling.
