Abstract
The present invention is a golf cup cutter sharpener. The sharpener consists of one or more grinding wheels affixed in a rigid housing. The grinding wheels are cylindrical metal elements covered by a removable, and thus replaceable, abrasive surface. The wheels are belt driven, and powered by a standard electrical motor. The grinding wheels are aligned according to the geometry of the sharpener. The angle of the wheels is chosen so as to provide the proper angle of grinding to create a sharp cutting edge. If two wheels are utilized, the wheels are positioned to contact two non-adjacent scallops of the sharpener. A mandrel holds the cup cutter in place while the sharpening operation is taking place.
