How do you know when it’s time to sharpen the skates?
Sharpening Terms...
Hollow: refers to the curve on the bottom of the blade that creates your four edges that results from skate sharpening. It determines how much edge you have and how pronounced your edges are. The hollow radius refers to the exact size of the grind. The radius size varies depending on the skill and size of a player, as well as the temperature of the ice he or she skates on. A shallow radius means that you have less edge, but typically more control and speed.
Glide Surface:The 20-60 mm of the blade that is actually in contact with the ice most of the time. It should be centered properly according to a skater’s center of gravity and skating style.
Profiling: The process that determines the length of the glide surface. Because only a small area of the blade is treated, a skater can get a longer life out of their blade than he might with traditional rockering.
Rocker: an outdated practice that shapes of the blade from front to back. The length of a “rocker” means that the blade will fit the arc of a circle that large. Profiling is a much more precise and sophisticated way of determining blade shape.
