ABSTRACT:
Golf clubs and of the wood type have a relation between the axis of the shaft and the hitting spot on the head face thereof such that, under the assumption that the relation between the axis of the shaft and the head face both thereof in a plane squarely facing a golfer using the golf clubs is negative when the hitting spot is before the axis in the direction of ball's flight and positive when the hitting spot is after the axis in that direction, the distance y between the axis and hitting spot is greater than -3 mm and this is attributable to bending of the neck of the head, the shaft being straight.
