The Edge Tuner tool combines the practical with the functional to easily make adjustments anywhere. The large surface rests easily against your base to allow you to position the file at the correct angle and achieve a perfect edge. With two angles available: 0 degrees for soft to normal snow, and 2 degrees for firmer snow, in hard and icy conditions. The two-sided file lets you choose an aggressive double-cut pattern to remove a lot of material quickly, or a traditional single-cut pattern for more precise adjustment. We also add an extra file to keep your edges in top condition for longer.
