The most common skate sharpening angle when it comes to Ice Boards is a 45-45 degree vee-shape (knife-shape).
Ice Board skates – Obtain a smooth and even glide surface
Build a simple sharpening stand for your Ice Board skates, as shown in the picture. Use a hand held belt sander to obtain a smooth and even glide-surface, and make sure not to add any extra pressure. I used fine and extra fine belt sand-paper and finished off with a water-stone to obtain the perfect final finish.
