You are bidding on a Kuu Sport Ice Buster 90 Degree ski and snowboard edge file. I bought it new and never used it. It comes with their combo file which can be removed or replaced. It is a precision edge guide file for 90 degree (Zero), for sharpening the edges on your skis or snowboard. Comes with the clear plastic carry case.  Retail for it is around $27.00. Please read my description carefully and ask any questions before bidding, as I will only accept returns if I misrepresented the condition. Thanks for taking time to check out my listing.
