发明名称 Putter
摘要 A putter uses an angled mirrored upper club surface with a deeply scribed and pigment filled line to act as a sighting device. In one embodiment, a clear plastic block has a bottom surface coated with a highly reflective coating. A pair of lines are scribed on upper and lower surfaces of the block and must be aligned while the target is sighted in the mirrored surface. Other embodiments utilize deep grooves formed in the top of a mirrored or unmirrored club surface.
