Here is How to Know if Your Hockey Skates Are Sharp Enough:
Bear in mind that how sharp you keep your skate blades is subjective and that it somewhat depends on your skating style and performance goals. If you're a beginner, don't make your skates too sharp or they will grip the ice too much and make it hard for you to stay in control when turning and stopping.
You ought to log the number of hours you're on the ice (use your smartphone) to see when they begin to become dull. This will help you determine when you'll need to sharpen them again.
