1. A progressive set of iron-type golf club heads, comprising:
- a first iron-type golf club head, comprising a body defining a striking face, a top line, a sole, a heel, a toe, and a first elliptical area of increased thickness positioned on a back of the striking face; and
a second iron-type golf club head, comprising a second body defining a second striking face, a second top line, a second sole, a second heel, a second toe, and a second elliptical area of increased thickness positioned on a back of the second striking face,wherein the second elliptical area of increased thickness is shaped more like a circle than the first elliptical area of increased thickness, wherein boundaries of the first elliptical area and the second elliptical area are defined by a protrusion on the on the back of the striking faces due to the increased thickness and wherein the first golf club head has a design loft that is lower than the design loft of the second club head.

Abstract
A set of progressive golf clubs with an elliptical pad construction on the back of the striking face that corresponds to a location, shape and size of a predetermined golfer'"'"'s impact pattern for the lofts and lengths of each of the golf clubs in the set. The elliptical pad progressively changes in location, shape and size from the long irons, to the mid irons, to the short irons, and to the wedges, based on the location, shape and size of a predetermined golfer'"'"'s impact pattern for each of the long irons, mid irons, short irons, and wedges.

11. A set of iron-type golf club heads comprising:
-
a first iron-type club head, a second iron-type club head, and a third iron-type club head, all of progressively varying design loft, wherein each club head has a body defining a topline, toe, sole, heel, hosel, and ball-striking face, and further wherein each club head includes an area of increased thickness on a back of the ball-striking face, wherein the area of increased thickness varies progressively with iron length through the set, wherein each area of increased thickness is progressively more elliptical as the iron-type heads have a lower loft, and wherein boundaries of the elliptical areas are defined by a protrusion on the on the back of the striking faces due to the increased thickness.
