A metal wood type golf club with improved performance characteristics is disclosed herein where the metal wood type golf club head will combined the performance characteristics of both a driver type golf club head and a fairway type golf club head. More specifically, the present invention relates to a golf club head with a volume of between about 150 cc to about 360 cc, a CG location between about 10 mm to about 20 mm above the ground, a face depth of between about 30 millimeters (mm) to about 65 millimeters (mm), a loft of about between 10 degrees to about 16 degrees, and a COR of about 0.790 to about 0.830, wherein the entire golf club has a length of between about 41 inches to about 45 inches.

Golf club with improved performance characteristics

A golf club head with an improved sweet spot, defined as a portion of the striking face that has at least 99.7% of the maximum ballspeed is disclosed herein. More specifically, the present invention discloses a golf club head with a significantly circular sweet spot that encompasses at least about 1.5% of the total striking face. A golf club head in accordance with the present invention may generally have a improved face geometry with an elliptical factor of greater than about 0.5, a beveled transition portion around the striking face of the golf club head, a variable face thickness region with decreases thickness, or even a tilted bulge and roll radius all helping improve the performance of the golf club head.

Golf club head with improved performance

A golf club head optimized for sound has a body that defines an interior cavity. The body includes at least one of a sole portion, skirt portion, or a crown portion. At least the sole portion is stiffened to provide a higher frequency sound. The stiffened sole portion increases the frequency range of the golf club head by at least 300 Hz with an overall frequency of greater than about 3000 Hz. The stiffened sole portion provides a higher frequency sound with a minimal increase in the overall weight of the golf club head. In one embodiment, the stiffened sole portion increases the weight of the golf club head by less than 10 grams with the overall weight of the golf club head less than 220 grams. In operation, the golf club head with at least the stiffened sole portion impacts the golf ball to provide an aesthetically pleasing sound.

Golf club head optimized for sound

A golf club with a multi-material face is disclosed herein. More specifically, the golf club head in accordance with the present invention has a striking face that forms a pocket, wherein the pocket is filled with a secondary material having a lower density to improve the performance of the golf club head. The multi-material face disclosed in accordance with the present invention may generally have a characteristic time slope of greater than about 5 and less than about 50, wherein the characteristic time slope is determined based on the various data points collected according to the United States Golf Association's (USGA's) Characteristic Time (CT) test.

Golf club head having a multi-material face

An iron type golf club head with improved performance is disclosed herein. More specifically, the present invention discloses an iron type golf club head having a frontal face portion made out of a lightweight material that is separate and distinct from the material used to form the remaining body portion of the iron type golf club head. The thinner material allows the frontal face portion of the iron type golf club head to be made thinner, yielding improved performance characteristics such as a higher Coefficient of Restitution (COR) of greater than about 0.770, a lower Center of Gravity (CG) location of less than about 5.0 mm from a ground, and a lower primary resonant frequency of less than about 5,000 Hertz.
