Patent ID: 7568978

Claim:
A portable tool for conditioning the ferrule of a cue stick, said portable tool comprising: a) a jig support body in the form of a tubular structure having a longitudinal bore there through, said bore having a longitudinal axis of symmetry, said jig support body further having a proximal end and a distal end, said jig support body configured whereby with said cue stick inserted into said bore at said jig support body's distal end the longitudinal axis of said cue stick is positioned along said longitudinal axis of said bore, b) a clamping device positioned on said jig support body whereby with said cue stick inserted into said jig support body said axis of said cue stick is fixedly held in alignment with said axis of said jig body by means of said clamping device, c) a removable cylindrical cap positioned on said proximal end of said jig support body, said cap having a longitudinal axis of symmetry positioned in alignment with said longitudinal axis of said bore, said cap further manually rotatable about said cap's longitudinal axis of symmetry, and d) said cap further comprising an abrasive planar surface perpendicular to said cap's longitudinal axis of symmetry, whereby said planar surface is in contact with said ferrule of said cue, and further whereby when said cap is manually rotated the surface of said ferrule is scored and cleaned by said abrasive planar surface.
