  • Patent number: 4850252
    Abstract: A ski edge tuner uses separately adjustable base and side edge tuning tool holding bodies, which are each pivotably carried by a common base platform, to sharpen and, if desired, bevel the metal edge surfaces of a ski. Bevel angles for each tool holding body, and hence for each ski tuning tool are individually selectable using bevel angle adjusting blocks which slide on wedging surfaces formed in the base platform of the ski edge tuner. Base and side surface tuning tools are carried in recesses in the ski edge tuner and can be quickly and easily removed.
