Abstract:
A head of an iron golf club, comprising:a face forming portion having a face formed on a forward surface thereof; and a sole forming portion extending rearwardly from a lower end of said face forming portion, said sole forming portion having sole formed on a bottom thereof, wherein a thickness of the head is defined by a distance from the forward face of the head to a rearward face of the head in a direction perpendicular to the forward face of the head, said thickness of the head at an upper end of the head being less than two-and-a-half times said thickness of the head at a middle portion of the head, wherein said sole forming portion is provided with a portion having a smaller specific gravity than that of a rest of said sole forming portion near said face forming portion, said smaller specific gravity portion having a length extending in a front to rear direction of the head, and wherein said sole forming portion extends rearwardly so that weight is redistributed to a rearward end of said sole forming portion in at least an amount corresponding to the reduction in weight of the head due to the presence of said smaller specific gravity portion, thereby substantially shifting a center of gravity of the head toward a rearward end of the head.
