Never lose your edge with the RaceWax Dual Edge Kit - Everything you need to professionally sharpen ski and snowboard edges. Side and base edge bevel multi tool (does both sides) that includes a metal file as well as a full set of three Swix diamond stones, a Swix deburring gummi stone, brass brush to clean your files, and ski brake retainers. Dial a precise side angle from 0 degree to 5 degrees and 0.5 to 1.0 degree on the base. Nine angles total. High quality Swiss-made ICECUT included (80 mm). NOTE: 80 mm is the maximum length file or stone that will fit into this tool. 70- or 80-mm stones are recommended. One Swix gray Gumi or Gummi Stone for prepping an edge, deburring as the final step in edge sharpening, or detuning. Swix 80-mm Diamond Stone Set, Three Stones: Red Coarse TA200SE= offers best cutting action (200 grit); Yellow Medium TA400SE= for routine edge maintenance and sharpening (400); White Fine TA600SE= for deburring and edge polishing (600) It is recommended that you set the edge bevels with the file and then replace the file with 70- or 80-mm diamond stones to maintain the sharpness; if you always use the metal file, you will wear away the edge. Bonus Benefit for this tool: If you don't know what base and side angles your ski/board are set to, this tool can help you find them. Before you start mark the metal edge with a sharpie, start the tool at the lowest angle and see if it removes the marking on your edge. Raise the angle step-wise and repeat until it removes the mark. That is your angle! Record the base/side angles for future reference. File cleaning brush for removing metal filings from grooves. Measures 3.25 x 0.6 x 0.4 inches. Ski brake retainers: two large (color may vary) ski shop quality bands. Detailed instruction card with links to video help.
