The KUU Pocket Sharpener Combo 88° & 90° is a compact, dual-angle edge tuning tool designed for on-the-go ski and snowboard maintenance. This versatile edge sharpener allows users to easily refine and maintain their side edges at two of the most common angles—88° for a more aggressive, race-style grip, and 90° for a standard, durable edge suitable for recreational use. Ideal for quick touch-ups between runs or while traveling, the tool includes a durable file insert that efficiently removes burrs and restores edge sharpness for better control and performance on hardpack and icy conditions. Its ergonomic, pocket-sized design makes it easy to carry and use without the need for a full tuning bench, making it a favorite among both recreational riders and competitive skiers who want reliable edge tuning anytime, anywhere.
