Abstract: A metalwood type golf clubhead including a clubhead body having a toe, heel, upper crown surface, bottom sole surface, side surfaces, rear surface and ball-striking clubface having at least one raised, elongated, aerodynamically shaped reinforcing and stabilizing member extending outwardly from the clubhead body and having at least one frontal ball-striking surface coincident with the ball-striking clubface. The structure provides improved weight distribution for better balance, additional strength and stability to clubhead and provides more effective aerodynamic surfaces to increase clubhead speed.

Abstract: A metalwood type golf clubhead including a clubhead body having a toe, heel, upper crown surface, bottom sole surface, side surfaces, rear surface and ball-striking clubface having at least one raised, elongated, aerodynamically shaped reinforcing and stabilizing member extending outwardly from the upper and/or bottom surfaces, and having a front ball-striking surface located perpendicular to and coincident with the ball-striking clubface. The structure provides improved weight distribution for better balance, additional strength and stability to clubhead and provides more effective aerodynamic surfaces to increase clubhead speed.

At least one dominant secondary weight member is combined with at least one auxiliary reinforcing and stabilizing weight member extending from an innermost secondary weight member surface across the rear face of the rear cavity.

Abstract: The present invention relates to an improved golf club head having a ball striking face with vertical grooves and intermediate vertical land areas between the grooves. The club head includes a resonator system having specific resonant frequencies which are determined by the specific variable width and depth combinations of vertical grooves and specific variable widths of the land areas between the vertical grooves. This controls the harmonics and feedback of a golf club head when it is used to stroke or strike a ball. In accordance with the invention, having more land area between the vertical grooves, creates a lower frequency resonance when striking a golf ball resulting in more energy transfer to the ball from a greater surface contacting the ball. Having less land area where the vertical grooves are closer together, creates a higher frequency resonance and somewhat less energy is transferred to a golf ball struck by the club head, thereby providing a softer feel.

Abstract: Golf clubs, golf shafts, and inserts for golf club shafts have a coil or coil-type insert for enhancing swing weight control, stiffness and flex control, shock absorption and vibration elimination or reduction. The insert has a central section and a pair of couplers integrally formed on opposite ends of the central section to attach to the shaft or club head.
