Swix's Sidewall Cutter is a specialty tuning tool used to cut the sidewall of the ski back to expose more of the steel edge for easier filing. Used only on full sidewall skis the sidewall cutter removes millimeters of material at a time to expose more edge so that you can file correct angles. This tool should not be used by inexperienced tuners or those who have not had proper instruction as you can damage the ski.
