Technology – Attention to detail

Generally, to keep costs down, short track ice blade manufacturers batch grind the steel quickly. The heat from this process warps the steel and makes bending the blades a difficult process. The Ultrasprint is ground slowly with highly specialized grinding wheels to avoid excess heat. This slow process creates a perfectly straight piece of steel without warping.

After grinding, a normal short track blade is inserted into the tube for gluing. Before gluing the Ultrasprint undergoes a specialized polishing process called ‘brilliance polishing’. This gives the steel a very highly polished finish for better glide.

When the steel is glued into the slot in the tube, there is a gap between the steel and the tube to allow room for the glue. This gap allows the steel to warp. Glued in a jig that holds the blade in the tube, the Ultrasprint dries in place. Each blade takes 8 hours for the glue to set so it is an extremely slow process but the end result is a perfect blade.
