Profiling template compatible with the Prosharp AS 2001. Profile grinding involves shaping the steel to the desired form to suit your skating style. In hockey, radius grinding is used almost exclusively, resulting in no flat surface beneath the blade. The radius is specified in meters, where the value represents the radius of a circle. There are also combination radii, where, for example, you can have one radius from the center forward and another from the center backward. Example: Detroit 1 = 3-meter radius from the center forward, 6-meter radius from the center backward. Quad = a combination radius template with four different radii. Zuperior = a three-part radius with a very short radius at the front, a longer one in the middle, and an even longer one at the rear. Ellipse = the latest from Prosharp, offering a combination of maximum power and feather-light maneuverability.
