Golf club set

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.

         2 . 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 and center-of-gravity depth ZG of the golf club head becomes shallower,    wherein center-of-gravity height HGR of the golf club head of each golf club is constant among the golf clubs.

         8 . 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 each of golf club heads includes a hollow portion: and    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 and center-of-gravity depth ZG of the golf club head becomes shallower,    wherein center-of-gravity height HGR of the golf club head of each golf club is constant among the golf clubs.
