Patent ID: 8475293

Claim:
An iron type golf club head comprising: a frontal face portion, made out of a first material having a first density, connected to a forward portion of said iron type golf club head; a body portion, made out of a second material having a second density, connected to a rear portion of said frontal face portion providing a structural support for said frontal face portion; wherein said first material is different from said second material; wherein said first density is lower than said second density; and wherein said iron type golf club head has a face replacement ratio of greater than about 0.9 and less than about 1.0; said face replacement ratio is calculated by dividing a cross-sectional height of said frontal face portion by a total cross-sectional height of a striking surface of said iron type golf club head, wherein said iron type golf club head has a velocity factor of less than about 32,500 mm/s; said velocity factor is determined by multiplying a CG height from ground with a primary resonant frequency all divided by a COR of said iron type golf club head.
