sole means extending rearwardly from the lower portion of the face;

an inner side portion and an outer side portion extending rearwardly from and adjacent to the face and upwardly from the sole means;

a substantially continuous convex surface extending rearwardly from the upper portion of the face and inwardly from the inner and outer side portions and forming the upper surface of the club head;

a concave surface, including an inner recess between the inner and outer side portions, extending substantially continuously upwardly and rearwardly from the sole means to the convex surface, the juncture of the convex surface and the concave surface defining an edge, said edge extending in a curve between the outer side portion and the inner side portion; and

weight means disposed in the head adjacent the inner and outer side portions for adjusting the balance of the club head.

2. The apparatus of claim 1 in which the sole means includes a pair of apertures for receiving the weight means.
