Hollow sharpening

Good skate sharpening is as essential as getting the right fitting skates and ensures all ice skaters to skate to the best of their ability. Without it, skaters would lose grip on the ice, constantly slip over and wouldn’t pick up much, if any, speed.

The skate blade can be sharpened in many different ways. Perhaps the most common is the so-called. grooving and hollow sharpening. In this form of sharpening, a chute is sharpened on the skate blade. With the trough in the middle of the skate blade, two sharp edges are formed in the skate, on which the skate slides along the ice.

The depth of the skate sharpening, i.e. the magnitude of the radius, can influence how the skate behaves on ice.

  • A small radius (e.g. r = 10mm) creates extremely “sharp-feeling” skates, allowing the blade to sink more into the ice. Suitable for an active attacker who wants maximum grip on ice. Skating with a small radius consumes a lot of force, and the skate does not glide as well as with a larger radius.
  • A large radius (eg r = 30mm) creates good glide and light skating. However, a large radius does not provide as good grip as a small radius. The large radius is well suited for a defender who needs a long glide and effortless skating, eg backwards.
  • A good basic setting for the skate is in the radius r = 20 ... 25mm. In this case, the skate works well both in the attack head and in longer slides

In grooving, it is extremely important that the groove is always in the middle of the skate. Therefore, when sharpening a groove sharpener with a sharpening machine that is adjusted according to the skate, the thickness of the skate blade must always be measured before sharpening!
