ABSTRACT:
An improved golf club head and set of clubs using progressively sized heads. The club head, of the sort generally referred to as "irons" has the usual striking and opposed back faces, an upper edge, a sole, a heel adjacent to the hosel and a toe opposite the heel. A slot of selected depth is provided across the back, extending diagonally from the upper heel area to the lower toe portion, so as to provide a thin central region and two thicker regions at the intersection of toe and upper edge and at the intersection of heel and sole. The resulting head has a diagonal balance along a line extending along the major axis of the normal elliptical pattern of ball impacts against the striking face, which results in a larger and more desirably oriented "sweet spot". The clubs in a set of irons may have progressive top edge thicknesses so that all top edges appear to have the same width in use, progressively increasing sole width from long to short irons to provide optimum ground friction characteristics and progressively increasing heel to toe lengths going from short to long irons. The hosel typically has an airfoil shaped cross section with the sharp trailing edge extending perpendicular to the intended direction of ball flight.
