Abstract:  
Metallic golf club heads are improved by a treatment which involves shot peening the exposed ball striking surface of the metal head without creating any noticeable change in appearance of the head. As a result of the shot peening treatment there is improved feel with minimal vibrational feel in the hands of the user when the user strikes a golf ball thus providing better control and increased distance of the shots.
