Fast & Sharp

Indoor Versus Outdoor Rinks Skaters who regularly use outdoor rinks require more frequent appointments at the grinding table than those who use indoor ice surfaces. Outside, naturally occurring abrasive material, such as sand, salt, and dust particles find their way to the ice, and inevitably to skate blades. In addition, outdoor ice tends to be harder because it lacks the luxury of temperature regulation. For this reason, skaters require sharper blades for more efficient glide.
