Iron golf club head

Golf club head

A golf club head with low peripheral and rearward weighting includes C-shaped and annular weights connected with at least one of the rear and bottom surfaces, respectively, of the head. The weighting within the peripheral weights is adjustable between the heel, rear, and toe portions of the head to customize the weight distribution of the head in accordance with a golfer's swing. The added weight and its orientation increases the moment of inertia of the head and reduces the rotation thereof.

Golf club head with peripheral weighting

A golf club head () having a body () with a front wall () with an opening () and a striking plate insert () is disclosed herein. The striking plate insert () preferably includes an outer layer () and an inner layer () that are joined together by an explosion bonding process. The inner layer () is preferably composed of a material that has a lower yield strength than that of the outer layer (). The explosion bonding process results in the striking plate insert having an increased yield strength relative to the yield strengths of the individual layers. The golf club head () preferably has a moment of inertia, Izz, about the Z axis through the center of gravity of the golf club head ranging from 2700 g-cmto 4000 g-cm.

Golf club head with a face insert

A set of golf club irons of the blade type is characterized by a weight pad behind the impact area of the club face which progressively increases in height through the set from the long irons to the short irons. In addition, the thickness of the sole portion of each head increases through the set to progressively increase the weight at the bottom of the club heads. The clubs provide improved feel to the golfer which enable the golfer to work the ball more easily during execution of a golf shot.
