ABSTRACT:
There is disclosed a design concept for a set of golf club irons including at least a first and a second club, wherein each club comprises a club head and a shaft. Each club head of the set includes a hosel portion to which the shaft is attached and a blade portion, with the blade portion including a substantially planar face for striking a golf ball and a back portion opposite said planar face. As with all iron clubs the substantially planar faces on the respective club heads of the set are disposed at varying angles with respect to a vertical datum line to provide progressive degrees of loft. In one preferred form the back portions of each club head of the set include a cavity formed therein, with the volume of the cavities in said clubs decreasing from the lower lofted clubs of said set to the higher lofted clubs. Further, the hosel length on said club heads increases from the lower lofted clubs to the higher lofted clubs of said set, such that the hosel length may be selected to provide a relatively uniformly located center center of mass for each club head in the set. The feature of varying hosel length and cavity size may be employed separately or in combination. Further, there is disclosed an iron club head design wherein the back portion of the blade includes a rib extending about the finished surfaces of said back portion, which rib can be ground off to adjust club head weight without damaging the club head finish.
