  • Patent number: 6224502
    Abstract: An implement for repairing ball marks on golf greens, the implement having a grasping portion at a proximal end and at least one prong at a distal end with a ramp-like profile ending in a transversely oriented abutment in a mediate region. The abutment provides a surface against which an index finger of a user can rest to apply increased pressure to insert the implement into a golf green. The method of using the implement includes inserting the implement adjacent the ball mark and moving turf laterally. In those instances where insertion of the ramp-like prong or prongs is insufficient to repair the damage of the ball mark, the method further includes rocking the implement about the distal end to move the turf laterally.
