2086421 9219327 PCTABS00017 A golf club for improving the flying distance by removing phenomenon of pulling the shaft occurring as a reaction to phenomenon of prostrated toe liable to occur particularly to a skilled player enjoying a high head speed and further improving the head speed, and for improving the directional stability of a hit ball by removing phenomenon of prostrated toe and changing the design such as in the face resulting therefrom, the golf club being characterized in that the center of gravity of the head is shifted from the toe end to the shaft end by modifying the head shape by decreasing the volume of the head by a certain amount at the toe end on the rear side thereof and increasing the head volume at the shaft end on the rear side by an amount equal to the amount decreased, thereby reducing the rotational radius of the head about a vertical line, as a rotational center line, when the golf club is suspended at the upper end of the shaft thereof. Furthermore, with a metal wood club, a head is provided with a face which comprises a spherical face formed in such a manner that the curvature in the transverse width direction becomes substantially equal to that in the vertical width direction. Moreover, with an iron club, the shape of the back of the face portion is formed by extending the central axis a of the above hosel substantially to a position where it passes through in the transverse direction, and the increase in thickness of the back of the neck portion is effected by moving a part of the weight at the toe end.
