Patent attributes
A golf club producing less drag on a golf club during a swing than a conventional golf club with drag-reducing structures having different surface areas on specific portions of the golf club, the structures divided into a first portion on a shank, a peripheral portion surrounding a ball impact face, an upper surface, toe, hosel, rear face, sole, and heel of the club head; a second portion on a forward face outer portion; third and fourth portions on a respective impact face second ring and first ring; and a fifth portion centered on the impact face. The structure surface area progressively decreases from the fifth portion, to the fourth portion and then to the third portion. Each drag-reducing structure of the first and third portions has an equal surface area, while each structure of the second portion has a surface area larger than each structure of the first portion.
