<p>The inventions published consist of "split-level-step" between bat handle and contact section. This said step provides the here newly invented concept of critical holding points (called as C.H.P.) for the thumb and last three fingers. These fingers can grip firmly onto the said step. This allows better swing of the bat, angle control, flexibility of bat manipulation and power. These C.H.P. also provide the proper gripping areas so that the finger deformation problem is less likely to happen. In addition, it is physically less straineuos for the wrist and fingers, so the better power and performance of the players can be maintained longer naturally through the games.</p> |
