For over 80 years, Holmenkol has been dedicated to the production of the finest ski waxes available. Today, they lead the way, with the introduction of nano technology, combining sport with ground breaking science to produce a comprehensive line of waxes and tools, proven in World Cup use, and suitable for all types of winter sports enthusiasts. The Holmenkol Ergo Pro Side Edge Tool is a high quality ergonomic edge sharpener with glide roller bearings on the base. The Ergo Pro Side Edge professionally sharpens the steel edges of skis and snowboards. Sharpening angles can be adjusted from 90°(0°) to 85°(5°) The tool can also hold diamond files and cross cut files. It comes complete with an Ice Cut file for general side edge tuning and sharpening. Material: Plastic construction with ball bearing wheel guides for easy movement up and down the ski or snowboard base Packaging: Includes ICE CUT standard file Out Opinion Small enough to carry on trips, but durable enough for the home workshop, you can replace the supplied file with any other 70 mm-100 mm tuning file, so if you have a diamond file such as our Moonflex diamond files, its a faster and easier way of finishing off your edges with the correct angle. Is This For Me? If you wish to ensure the geometry of your side edges is always correct, or wish to experiment then this is a great tool. For any side edge tuning or servicing, a tool like this is a must!
