Are Your Skates Too Sharp?
Most players skate on a hollow nobody chose — a shop default, an older sibling's cut, whatever the skates came with. Our new report works through what that number actually does. The groove under the blade runs from 0.0044 inches deep at a 3/8-inch hollow to 0.0016 at 1 inch, and the trade-off is measured, not folklore: in University of Calgary sled tests, blade friction was 11 percent lower at a 1/2-inch hollow and 19 percent lower at a 3/4-inch hollow than at a deep 1/4 inch.
The right cut starts with weight and skill, not preference — a light beginner starts around 7/16 to 1/2 inch, a heavy, skilled skater can settle at 3/4 inch or shallower — and hard ice moves the answer one step deeper. Too deep is a failure of its own: edges that catch in stops and will not rotate in transitions.
