Abstract
Abstract Immediately above the connection at the center of the head of this golf putter to its shaft, the latter has a forwardly-extending elongated horizontal primary lower aiming portion perpendicular to the center of the forward face of the putter head. An upwardly-inclined intermediate secondary aiming portion of the shaft extends from the forward end of the lower aiming portion to the lower end of the handle-attached upper portion of the shaft which is approximately aligned with the rearward face of the putter head. The lower and intermediate shaft portions lie approximately in a vertical plane perpendicular to the forward face of the putter head and passing through the center of that forward face.
