## Abstract

A set of golf clubs with a plurality of at least two combinations of different lengths of a minimum of three golf clubs in each combination having progressive lofts that are matched to provide identical swing characteristics requiring unique loft and club length progressions to provide consistent yardage spacing between irons within a combination and between combinations. Each club in a combination is further defined by the shaft having an equal length; an identical swing weight, an identical grip weight and an identical head weight.

## Claims

### Claim 1

A set of a golf clubs having a plurality of at least two combinations of clubs; each combination of said set having a different length than the length of other combinations of said set; the club length difference between successive combinations of clubs being no less than 0.66 inches and no more than 2.33 inches; each combination including a minimum of three golf clubs; each of the minimum of three golf clubs in a combination defined as having the same length and are matched to provide identical swing characteristics; said combinations of said set having unique loft progressions between the clubs in the individual combinations, whereby each of the combinations is characterized by a loft difference between the individual clubs in any particular combination where the loft difference between the first, lowest lofted club and the second, higher lofted club in the same combination is no more than the loft difference between the second, higher lofted club and the third, highest lofted club in the same combination; each individual combination of clubs further defined as having loft differences between individual clubs that are no less than the loft differences between the same consecutive individual clubs of another combination as the length of the clubs in combinations increase; and, each club in any combination having an identical club head weight and each club having an identical swing weight.

### Claim 2 (depends on 1)

The set of golf clubs of claim 1 wherein each individual golf club includes a club head formed of a ball striking face, upper surface, bottom, toe, heel and rear surface including an integral rear weight; each individual golf club including a shaft and a grip at the upper end of said shaft.

### Claim 3 (depends on 1)

The set of golf clubs of claim 1 further defined by the height of said toe and the height of said heel in individual irons is the same for each individual club within each combination.

### Claim 4 (depends on 1)

The set of golf clubs of claim 1 wherein the loft difference between the highest lofted club in a combination and the lowest lofted club in an ad joining, higher lofted combination is no more than the loft difference between consecutive individual clubs in the prior less lofted combination and is no more than the loft difference between consecutive individual clubs in an adjoining, higher lofted combination.

### Claim 5 (depends on 4)

The set of golf clubs of claim 4 defined as having more than two combinations wherein the loft difference between the highest lofted club in a particular combination and the lowest lofted club in an adjoining, higher lofted combination is no more than the loft difference between the highest lofted club in the same adjoining, higher lofted combination and the lowest lofted club in the next adjoining, higher lofted combination.
