WintersteigerSki Man Diamond Stone File - Ski and Snowboard Edge Sharpening Tuning Tool

This diamond stone is a good thing to have for deburring or polishing your edge depending on which stone you have. I have a couple of these that I keep on a lanyard. My most recent purchase is this medium grit stone. Please be advised that the 70mm length is the entire size of the plastic that holds the stone. This stone is pretty small at 50mm X 20mm, actual stone dimensions. This is just shy of 2" long by .8" wide (for the imperial in you). Like I said, these stones are great but small.
