Abstract

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 toward the hosel by a first distance. The mid-irons have a second center of gravity positioned horizontally from the face center toward the hosel by a second distance. The short irons have a third center of gravity positioned horizontally from the face center toward the hosel by a third distance that is greater than the first and second distances.

First claim

What is claimed is:

1. A set of golf clubs comprising at least a first golf club, a second golf club, and a third club, wherein:
the first, second and third golf clubs each comprising a heel, a toe, an upper surface, a lower surface, a hosel and a front face having a face center, and
the first golf club further comprising a first loft angle (LA 1 ) of between 15 and 25 degrees and a first center of gravity positioned horizontally from the face center toward the hosel by a first distance between about 1 mm and 3 mm,
the second golf club comprising a second loft angle (LA 2 ) of between 26 and 36 degrees and a second center of gravity positioned horizontally from the face center toward the hosel by a second distance of between about 1 mm and 3 mm, and
the third golf club comprising a third loft angle (LA 3 ) of between 37 and 47 degrees and a third center of gravity positioned horizontally from the face center toward the hosel by a third distance,
wherein the first distance and the second distance are approximately constant and the third distance is at least 30 percent greater than the first distance and at least 30 percent greater than the second distance.

2. The set of golf clubs of claim 1 , wherein the third distance is between 35 percent and 70 percent greater than the first distance and between 35 percent and 70 percent greater than the second distance.

3. The set of golf clubs of claim 1 , wherein the third distance is between about 3 mm and 4 mm.

4. The set of golf clubs of claim 1 , wherein, for the third golf club, the third distance is greater than about 15 percent of a center of gravity position measured vertically from the ground.
