ABSTRACT:
Two embodiments are disclosed for a right circular cylindrical shaped golf clubhead which, when provided with the essential shafts and gripping devices, can be used for chipping and putting a golf ball with low flight trajectory and pronounced rotational overspin and backspin characteristics. The preferred embodiment is manufactured from tropical hardwoods and has a geometry based on functions of a base diameter "D" of an impacting cylinder. The clubhead comprises tapered underfaces, a tapered heel face, grooving on portions of the impact surface to promote spin momentum, swingweight ports, swingweighting material and an upright shaft and ferrule. A second embodiment is metallic in construction, employs the same base diameter "D" an operates on the same principles as the preferred embodiment, except that the clubhead cylinder is curved along its horizontal centerline and is of uniform circular section over its entire length. The clubhead comprises a metallic curved tube having swingweight and closure caps, grooving for spin effect on the full length of portions of the cylinder, and a metallic hosel provided for the purpose of attaching a standard golf club shaft.
