Serious skiers and snowboarders, this RaceWax 3-piece bevel guide set is exactly what you need for precision edge tuning at home! You get all three essential angles in one complete set: the aggressive 87/3 degree for advanced skiers and racers who need maximum grip and bite on hard snow, the versatile 88/2 degree for intermediate to advanced riders wanting balanced performance, and the forgiving 89/1 degree for beginners to intermediate skiers preferring smoother turns. Each guide is machined from high-quality hard aluminum with a durable stainless steel base contact plate that measures approximately 4.7x1.5 inches - large enough for stable sharpening yet compact for easy handling. The guides work with skis and snowboards having metal edges in the 3-4mm thickness range, covering most modern equipment. The precision machining ensures accurate, consistent edge angles every time you tune your gear, giving you that razor-sharp edge that makes such a difference in performance on the mountain. While files and clamps are sold separately, these guides work with standard sharpening equipment you likely already own. Whether you're maintaining your own gear or helping friends with theirs, having all three angles means you're prepared for any skill level or snow condition. Properly tuned edges not only improve performance but also enhance safety by providing reliable edge control when you need it most. This professional-quality set pays for itself quickly compared to shop tune-ups and ensures your equipment is always ready for optimal performance on the slopes!
