<p>PURPOSE:To provide a golf club head whose center of gravity is low. CONSTITUTION:The concave 12 is made in the sole part 7, and installed on the concave 12 is the weight 15 whose specific gravity is larger than the material of the head 1. In this way, the center of gravity of the head can be substantially lowered. In addition, the distance between the center of gravity G and the face 5 can be extended and the sweet area on the face 5 can be widened, without reducing the strength of the head 1.</p> |
