Perfect for games and practices alike, this device will ensure every goalie has maximum mobility with sharp, well-maintained edges! The Edge Again process does not effect the hollow or the contour of the blade that were created with a conventional skate sharpening machine. It was designed by former NHL player, Chris Kontos, and is widely used across the NHL and minor hockey associations worldwide. Price includes the device itself and one Diamond Coated Tusk.
