Hockey Skate Sharpening Explained
Barn Garb Hockey ThreadsWalk into any skate shop long enough and you’ll hear the same question over
and over:
“What hollow do you want?”
If you’re new to hockey, that question can make you feel like you missed a meeting. And if you’ve been around the game for years, you probably already know this: half the time, players are just repeating whatever cut they’ve always gotten.
So let’s make it simple.
What is Radius of Hollow?
Radius of Hollow, usually shortened to RoH, is the shape ground into the bottom of your skate blade when it gets sharpened.
That cut creates two edges on your steel:
- an inside edge
- an outside edge
The depth of that groove affects how much your skates grip the ice.
Smaller number = deeper hollow = more bite
Larger number = shallower hollow = more glide
That’s the part that trips people up.
A 1/2" hollow is deeper than a 5/8" hollow.
A 3/8" hollow is even deeper.
A 3/4" hollow is more shallow.
Bite vs glide
This is the easiest way to think about it.
More bite
A deeper hollow helps your skates dig into the ice more.
That can help with:
- hard cuts
- quick starts
- tighter turns
- feeling locked in on your edges
But too much bite can also feel sticky. Some players feel like they’re fighting the ice instead of moving over it.
More glide
A shallower hollow gives you less resistance and more flow.
That can help with:
- smoother stride
- better glide
- less drag
- less fatigue over time
But if you go too shallow, you can feel like you’re washing out in turns or slipping when you try to really lean on an edge.
If you’re not sure how often you should be sharpening, that’s a separate piece of the puzzle.
Maintain Your Skate Edges
Keeping your blades protected and consistent between sharpenings helps your skates feel the way they should.
Common hockey hollows
These are the cuts most players will hear about most often:
3/8"
Very sharp with a lot of bite. Usually too aggressive for many adult recreational players, but some lighter or edge-heavy skaters like it.
1/2"
A very common cut and a standard starting point for a lot of players, especially youth players.
5/8"
Another very common starting point, especially for adult players. It gives a little less bite and a little more glide than 1/2".
3/4"
More glide, less bite. Often preferred by bigger players, stronger skaters, or people who feel like 1/2" is too grabby.
Major hockey gear guides commonly point players toward 1/2" or 5/8" as standard starting points, with shallower cuts often making more sense as player size and strength go up.
So what cut should you start with?
There isn’t one perfect answer, but there is a very good starting point.
Good starting point for most youth players
1/2"
Good starting point for many adult rec players
5/8"
That lines up with guidance commonly published by hockey equipment specialists: youth and lighter players often start deeper, while adult and heavier players often move a little shallower.
What affects your ideal hollow?
1. Your weight
In general, heavier players can often handle a shallower hollow because they already put more force into the ice. Lighter players often need a little more bite to get the same feel.
2. Your skating level
Beginners often like more bite because it can feel more secure. More experienced skaters sometimes move shallower as they get stronger and want more glide.
3. Ice conditions
Soft ice and hard ice can change how a cut feels. A hollow that feels great at one rink might feel off at another.
4. Your skating style
If you’re a player who really leans into edges, cuts hard, and likes that locked-in feel, you may prefer more bite. If you like speed, flow, and a less grabby feel, you may prefer more glide.
Signs your hollow might be too deep
You may be too sharp if:
- your skates feel grabby
- you lose glide too quickly
- your stride feels heavy
- transitions feel sticky
- you feel like you’re working too hard to move
Signs your hollow might be too shallow
You may be too shallow if:
- your edges slide out in turns
- you feel unstable stopping
- you lose confidence leaning into crossovers
- starts feel sloppy
-
you keep saying your skates feel “dull” right after a sharpening
The best way to find your cut
Here’s the smartest way to do it:
Stick with one hollow for a few skates.
Pay attention to how it feels.
Then make small changes.
Don’t jump all over the place. Go from:
- 1/2" to 5/8"
- or 5/8" to 3/4"
Small changes are easier to notice and easier to trust.
A simple cheat sheet
Choose more bite if you want:
- stronger edge grip
- tighter turns
- more confidence stopping
- a more locked-in feel
Choose more glide if you want:
- easier speed
- smoother stride
- less drag
- a freer feel on the ice
If you’re dialing in your overall setup, it also helps to understand how your stick and gear work together.
Final word
If you’re new to hockey and just want a clean answer, start here:
Youth player? Try 1/2".
Adult rec player? Try 5/8".
That won’t be perfect for everyone, but it’s a solid starting point.
From there, let your skates tell you the truth.
Because once you understand hollow, that skate shop question gets a whole lot easier to answer.
