This tool is something everyone needs in order to sharpen race or carving skis with the correct side bevel.  Unlike the sidewall cutters with a round or square blade, this tool uses a panzar file to remove the 2nd edge and to shape sidewalls in the tip and tail area of the ski.  This tool reduces the problem of skipping or chopping into the sidewall like a normal cutter can do.  Create a smoother finish  with the 70 Deg Sidewall Shaper / 2nd Edge Planer
