US Patent 9604108 Parabolic golf club system

A parabolic golf club system having a club head consisting of a parabolic path with a club face positioned coincident with the directrix and hosel (shaft) positioned at the focus. In other embodiments bores may be added along the parabolic path where various weights are installed to alter the club head properties such as MOI, CG, and overall mass. In other embodiments a substantially parabolic shaped bore may be formed in the club head allowing installation of parabolically shaped weights, weight plates, weight cartridges and the like to further alter club head properties. Further customization is achieved by allowing a golfer to select from various face inserts, face patterns, hosel configurations, and sight aid choices.
