A golf club putter head including an elongated body formed of a first metal and having an upright front portion defining a ball striking face, enlarged heel and toe portions symmetrically shaped about a vertical central axis of said body, and a horizontal bottom portion defining outer portions of beveled bottom surfaces. The front and bottom portions have a thickness at each central portion thereof which is substantially less than a width and a height, respectively, of the heel and toe portions. A slanted elongated cavity having a longitudinal axis receives and secures a lower distal end of a golf club shaft. A sole plate formed of a second metal is secured within a mating slot formed into only a central portion of the bottom surface. A front edge of the sole plate also forms a lower central portion of the ball striking face while a bottom surface of the sole plate is continuous with the bottom surfaces of the body. A balance weight formed of a third metal denser than that of the first metal is positioned and secured into a mating cavity formed into the bottom surface of the heel portion to cause the putter head to be balanced about the longitudinal axis of the golf club shaft.
