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.

Progressive iron set

A set of golf clubs including golf club heads having improved mass distribution characteristics. The set includes golf club heads having a club head main body including a hitting face and a face support, a muscle back shell and a weight insert.

Iron golf club head cavity

An iron type golf club head with improved performance is disclosed herein. More specifically, the present invention discloses an iron type golf club head having a frontal face portion made out of a lightweight material that is separate and distinct from the material used to form the remaining body portion of the iron type golf club head. The thinner material allows the frontal face portion of the iron type golf club head to be made thinner, yielding improved performance characteristics such as a higher Coefficient of Restitution (COR) of greater than about 0.770, a lower Center of Gravity (CG) location of less than about 5.0 mm from a ground, and a lower primary resonant frequency of less than about 5,000 Hertz.
