Abstract
An improved set of golf club irons wherein each golf club iron club head has a structure for redistributing weight of the club head towards the perimeter thereof particularly in the rear cavity region. This is accomplished by enlarging the rear cavity surface, creating an undercut between said rear cavity surface and cavity perimeter further redistributing available weight toward the club head perimeter. In addition, the club head face thickness is reduced between the rear cavity surface and hitting surface allowing additional weight to be redistributed to the club head perimeter resulting in a larger thin faced cavity. The large thin faced cavity is reinforced by means of a lightweight web-like structure comprised of thin lightweight buttresses which protrude outward from the center of the cavity and intersect with the undercut and perimeter of the cavity. The buttresses taper from their narrowest diameter at their intersection with the cavity surface to a greater diameter at their non-intersecting outer surface and the buttresses greatest diameter is at the point where the buttress intersects with the perimeter of the cavity. The lightweight web-like structure is comprised of tapered buttresses which intersect with the rear cavity surface and cavity perimeter and serves to strengthen and reinforce the hitting surface of the club head, keeping the hitting surface rigid during impact with the golf ball thus eliminating face deflection during impact and providing maximum energy transfer to the golf ball.
