CO-FORGED GOLF CLUB HEAD AND METHOD OF MANUFACTURE
First Claim
1. A forged golf club head comprising:
- a body portion having a striking surface made out of a first material; and
at least one weight adjustment portion made out of a second material encased within said body portion;
wherein said at least one weight adjustment portion is encased monolithically within said body portion without any secondary attachment operations, andwherein said first material has a first flow stress at a first forging temperature, and said second material has a second flow stress at a second forging temperature;
said first flow stress and said second flow stress are substantially similar to one another.

Abstract
A co-forged iron type golf club is disclosed. More specifically, the present invention discloses a co-forged iron type golf club with the body portion made out of a first material and at least one weight adjustment portion monolithically encased within the body portion of the co-forged iron type golf club head without the need for secondary attachment or machining operations. The present invention creates of an iron type golf club head from a pre-form billet that already contains two or more materials before the actual forging process resulting in a multi-material golf club head that doesn'"'"'t require any post manufacturing operations such as machining, welding, swaging, gluing, and the like.
