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 a secondary recess which has a volume smaller than the volume of the main cavity and a volume per unit length that increases in a direction toward the toe of the club head.
