发明名称 GROUND CONTACT PUTTER
摘要 A ground-contact putter is disclosed, the putter having a putter head that is rested continuously on an underlying putting surface during the putting stroke. The putter head has two end portions that contact the underlying putting surface and a centrally disposed ball-striking portion that is elevated above the putting surface. The putter head is oriented so that the longitudinal axis through the center of the putter head is perpendicular to the ball-strike direction. The putter shaft can be attached to the putter head either perpendicularly or at an angle. The putter head can optionally comprise a core, ground-contact surfaces and ball-strike surfaces made of different materials.
