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!


Skate blade profiling means changing the shape of the blade. Skates can be customized to each player, by profiling the blades. With the best profile for you, you will get the most out of your skates.

The correct profile for you can only be determined by testing multiple different profiles.

We have different profiles for different levels of skaters.

Single radius profiles are the basic profiles for skate blades. Small radius  gives good agility and acceleration, Large radius gives good balance and speed.

Cougar templates. Single radius with flat glide profiles are the basic profiles for skate blades, added with straight glide surface.
Flat glide surface gives excellent stability and glide.

The profile template of the Eagle series have two different radiuses.

The profile template of the Fox series consist of three different radiuses.

The profile templates of the Bear series consist of four different radiuses. Thanks to four different radiuses, good sliding and agility properties can be combined in the same profile.
