Abstract
A golf club is presented wherein the point of attachment, or the effective point of attachment, of the shaft to the club head is offset forward of the center of gravity of the head. The offset is in an amount such that the force couple created by translational acceleration of the head during the forward part of the stroke of the club is approximately equal to the torque required to overcome and opposite to the rotational inertia of the head to turn the club face from an angular position of other than perpendicular to the path of travel of the center of gravity on the backstroke to an angular position at impact substantially perpendicular to the path of travel of the center of gravity.
