Я играл в хоккей до занятий ФК, поэтому знаю наверняка, но если мне вы не доверяете, можете закрякать что-то типа: «hockey skates radius of hollow», — найдете, например: https://thehockeyguys.net/skate-sharpening-radius-chart/

| In the chart above, you can see that the 1″ radius is nearly flat. While this skate sharpening chart isn’t to scale, a 1″ radius is not commonly used for sharpening skates. In fact, for hockey players that are not goalies, it’s uncommon to have skates sharpened at anything greater than 1/2″. This is because hockey skates have a much thinner blade than goalie skates, so having an aggressive sharpening profile doesn’t reduce the gliding ability like it does in goalie skates. |
1 дюйм это примерно 25мм, 1/2 — 12.5мм.
