  • Patent number: 4815739
    Abstract: A golf putter which provides an enlarged "sweet spot" by connecting the shaft to a rearwardly extending semi-circular support so as to disjoin the shaft directly from the putter's faceplate or blade. The support consists of a plurality of spoke-like members extending to an attachment locus toward, but not touching the rear face of the faceplate; thus, causing the force of a struck ball to be transmitted to the shaft.
