Abstract: A method comprising, in a striking face of a golf club head, the striking face being formed of a first material having a first hardness, creating a plurality of initial grooves, the initial grooves having a first cross-sectional area (A1) and a first pitch (P1) such that A1/P1>0.0030 in. The method continues with modifying the initial grooves at least by positioning a second material in each of the plurality of initial grooves, the second material having a second hardness that is less than the first hardness, such that the first material and the second material form a plurality of final grooves each having a second cross-sectional area (A2) and a second pitch (P2) such that A2/P2

Abstract: An iron type golf club head including a striking wall having front and rear surfaces, a rearwardly extending perimeter-weighted element which includes heel, toe, top, and sole portions, the sole portion including a forward end, rearward end, and an upper surface, the intersection of the upper surface of the sole portion and the rear surface of the striking wall defining an interior sole line, the intersection of the upper surface of the sole portion and the rearward end of the sole portion defining a trailing-edge sole line, the perimeter-weighted element having one or more rearwardly-opening recesses therein; and a polymeric element affixed to the sole portion, wherein, in a imaginary vertical plane substantially perpendicular to the striking wall, when the golf club head is in an address position, the interior sole line is below the trailing-edge sole line.

Abstract: A golf club head having a striking wall having a front surface, and a rear surface, a top surface, and a sole portion extending rearwardly from the rear surface, the sole portion having a forward end, a rearward end, an upper surface and a lower surface. The intersection of the upper surface and the rear surface defines an interior sole line. The intersection of the upper surface and the rearward end defines a trailing edge. A region on the upper surface includes variation of the height of the trailing edge or exterior sole line relative to the height of the interior sole line.
