Made of premium steel, this is the only ski file with two different cuts: a coarse cut on one side to provide an high and frank bite, and a medium cut on the other side to provide a fine tune on edge sharpening. Now with the same file it is possible to remove the excess of sidewall material, to sharpen damage edges and to refine edge sharpening with high precision. Its dimensions are adapted to most sharpeners of 80mm in length. With this combination, sharpening it is not only faster but also much more easy: every skis or snowboard will have a precise and powerful bite.
