ABSTRACT:
A golf club has a head with a ball contact face and a shaft with surface indicia thereon or on an attachment thereto which may be used to provide for aligning the club face to be in a plane substantially perpendicular to a predetermined ball trajectory. The shaft or attachment may be of rectangular or square cross section with one or two surfaces extending normal to the club face and including contrasting indicia on such surfaces with respect to surfaces which extend parallel to the club face. The shaft may be of circular cross section with contrasting indicia provided on opposite sides of the shaft with respect to a plane through the central axis of the shaft and parallel to the club face, or include a hand grip with a generally flat thumbrest surface with contrasting indicia and extending in a plane perpendicular to the ball contact face. The club face is positioned in a plane perpendicular to a predetermined trajectory of the ball by establishing a line of sight parallel to the trajectory and rotating the club until the indicia on the shaft or handgrip surfaces which extend in a plane perpendicular to the club face is not seen. Alternatively, while addressing the ball in a conventional manner, the shaft is rotated about its central axis until the alignment surfaces extending parallel to the club face are not seen, or are seen to a desired degree.
