ABSTRACT:
A golf club for improving the flying distance of a ball overcomes toe-down phenomenon due to pulling of the shaft particularly by a skilled player enjoying a high head speed. The golf club further improves the head speed and the directional stability of a hit ball. The golf club has a center of gravity of the head shifted from the toe end of the shaft end by modifying the head shape to decrease the volume of the head by a certain amount at the toe end on the rear side thereof and to increase the head volume at the shaft end on the rear side by an amount equal to the decreased amount. This will reduce 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. 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.
