Abstract
As the club number increases so that the loft angle is larger, the center-of-gravity height HG of each head becomes larger, and the center-of-gravity depth ZG thereof becomes smaller. Each head is hollow, and a face portion becomes thicker in its lower portion. The back bottom thickness T is smaller in an iron shorter in club length.
Claims8
A golf club set comprising:
- a plurality of iron-type golf clubs different in club length, each golf club having a head whose loft angle increases step by step as club length thereof becomes shorter step by step,
- wherein as the loft angle of the golf club head of each golf club increases, center-of-gravity height HG projected on a face surface of the golf club head becomes larger, center-of-gravity depth ZG of the golf club head becomes shallower, and center-of-gravity height HGR of the golf club head of each golf club becomes lower.
