发明名称 Progressive iron set
摘要 The present invention is direct to a set of golf clubs comprising long irons, mid-irons and short irons. The long irons have a first center of gravity positioned horizontally from the face center by a first distance. The mid-irons have a second center of gravity positioned horizontally from the face center by a second distance. The short irons have a third center of gravity positioned horizontally from the face center by a third distance. The first distance and the second distance are preferably similar and the third distance is at least about 30 percent greater than the first and second distances. Preferably, the first and second distances are between about 1 mm and 3 mm and the third distance is between about 3 mm and 4 mm.
