ABSTRACT:
The inventions published consist of ‘split-level step’ between bat handle and contact section. This said step provides the newly inventions here the concept of critical holding points (called as C.H.P.)for the thumb, forefinger and any of other 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 provides the proper gripping areas so that finger deformation problem is less likely to happen.In addition, it is less strainuous physically for the wrist and fingers, so the better power and performance of the players can be maintained longer naturally throughout the games.Besides, the invented C.H.P.concept can also be achieved (although it is less ideal compared to the ‘split level Step’) without adopting the ‘split-level step’(that is with the bend/joint angle between the split level equals zero degree) by having ‘raised-height-block’ or raised step or ‘prolonged bottom handle’ front and/or at the back of the bat (see Y & Z in FIGS.3,4,5,6&7) so as to act as the C.H.P. as found in the split-leveled step (see X in FIGS.2,4&7) (Note: to use drawing7for article publication purpose).
