Abstract
The invention is directed to a golf club of the iron type having an improved mass distribution. More particularly, the rear portion of the club head has a main cavity extending towards the striking face and a peripheral mass belt extending around the main cavity defining heel, toe, upper and lower perimeter portions. The upper perimeter portion of the peripheral mass belt includes an elongated recess which is progressively connected to the upper edge portion of the club head along an undercut, the undercut having a height that generally increases in a direction toward the toe and a thickness with respect to the striking face that increases progressively in a direction toward the upper edge portion.
