Abstract
Abstract A golf club with a shaft entering the head near the heel but with the center of gravity in line with the shaft, a striking face extending on both sides of the shaft and an airfoil contour around the shaft, all contributing to a neutral stick effect eliminating twisting of the club during swing and impact with the ball.

Claim 1
Independent Claim
176 words
A wood-type golf club which comprises a head having a front striking face of desired pitch, a heel, a bottom wall, a top wall, said top and bottom walls extending rearwardly from the striking face and converging to a rim edge, an integral stem on said head extending upwardly from said top wall at said heel, said stem having an airfoil contour with a nose lying in a plane passing through the striking face and a trailing edge sloping from the upper end of said stem toward said rim edge, a shaft secured in said stem and head near the heel of the head, the distance between the periphery of said shaft and the opposing face of said heel along a line perpendicular to the shaft being not more than about 3/8 inches, said striking face of the head extending on both sides of the shaft centerline, and the center of gravity of said head and stem being substantially aligned with the centerline of the shaft to provide a neutral stick swing effect for the club.
