发明名称 Golf club set having progressively offset faces
摘要 An improved set of golf clubs wherein the face of the head of each golf club is offset relative to the central axis of the shaft of the golf club so as to provide a more consistent swing for golfers. The golf club set comprises progressively numbered wood clubs and progressively numbered iron clubs inclusive of a pitching wedge and sand wedge. The wood clubs and iron clubs each have correspondingly, progressively shorter and less flexible club shafts as well as correspondingly, progressively larger loft angles between the club faces and the shaft axes beginning with the lowest numbered club and progressing through the highest numbered club. The improvement comprises a set of wood and iron clubs each having at least four groups of face progression values. Each group of face progression values varies in accordance with each other group.
