Check the listing for details. Gatco Multicolor Knife Sharpening Kit with Case Plastic Metal Stone Materials. Color: Multicolor, Condition: Used. Listed at 19.00 USD. Gatco knife sharpening kit. Used but in good shape. One hone is missing from the kit. I think the one missing is an extra coarse. The case is broken at the hinge side so I installed two small hinges to keep it in place.
