Golf putter grip

Abstract

A golf putter grip comprises a main tubular body having a non-circular cross-section being symmetrical and remaining similar throughout its axial length and a flat front area being also along and throughout its axial length. The non-circular cross-section and the flat front area respectively have a width sufficient to have two hands cupped together at the same height and two thumbs placed side by side on the flat front area to hold the putter grip comfortably with minimal wrist breaking-down. The non-circular cross-section can be in a shape of flat-topped arch, flat-topped washer, modified rectangular, modified square, modified triangular, hexagonal and other non-circulars. The main tubular body is reversely tapered, and its reverse taper is sufficient in certain degrees to accommodate different finger lengths of two hands for reducing the gripping pressure, so as to make the gripping comfortable.
