US Patent 7993222 Table-tennis bat(pen-holding type)

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.
