Multi EdgerProduct information The Swix multi edger tool is all you need to sharpen and bevel your edges. You can set up the base and side edge in one tool! Dial a precise side angle from 0 to 5 degrees and 0. 5 to 1. 0 degrees on the basenine different angles in total. Always set the base edge angle before the side edge angle. We add a bevel to the base edge to make the skis more predictable or forgiving and bevel the side edge to give more grip on hard snow
