Hockey Skate Stones & Burr Stones: Complete Honing Guide (MIC-6 Diamond vs. Ceramic vs. Gummy Stones)
Walk down any youth travel, junior, or NHL bench and you will find one $20 tool in every equipment manager’s pocket: a hockey skate stone—also called a burr stone, skate honing stone, or deburring plate.
Yet most hockey players accidentally dull their freshly sharpened skates with the wrong stone—either because their cheap clay stone has worn into a curved groove, or because they tilt a soft rubber gummy stone across the hollow.
Inside the Utah Olympic Oval, Salty Gold Supply Co. is the only skate shop in Salt Lake City—and in the world—that uses Olympic Champion Speed Skating technology (poured MIC-6 cast aluminum monocrystalline diamond Pro Burr stones) to finish hockey and figure skate blades. Here is everything you need to choose and use the right skate stone.
1. Skate Stone vs. Burr Stone vs. Honing Stone: What’s the Difference?
Nothing in function—only the sport they came from:
- “Skate Stone” or “Honing Stone”: The standard hockey locker-room term for a flat handheld abrasive block kept in your skate bag or next to a home Sparx machine.
- “Burr Stone” or “De-Burring Plate”: The Olympic speed skating term for ultra-flat diamond and India stones engineered to shear microscopic steel foil burrs off 64-HRC runners without beveling a 90-degree edge by even half a degree.
By bringing Olympic speed skating’s MIC-6 cast aluminum flatness standard over to hollow-ground hockey runners, you get cleaner bite and noticeably faster glide than any $7 vending-machine stone can produce.
2. Why Ordinary Ceramic & Gummy Stones Roll Your Hollow Edge
When a grinding wheel cuts a 1/2" or 5/8" hollow down the bottom of your hockey blade, it pushes a thin, feathery ribbon of metal—the burr—outward over the side of each edge. If you skate on an un-deburred blade, that fragile foil folds over on your first hard stop and makes your skates feel dull.
The catch? Soft aluminum oxide stones wear down (“dish out”) in the middle after a few months, and soft rubber gummy stones compress under your thumb. The moment a dished or flexible stone wraps even 2 degrees around the corner of your steel, it rounds off the sharp apex of your hollow. A stress-relieved, cast aluminum Salty Gold MIC-6 Diamond Skate Stone cannot flex and never dishes out—so it contacts only the flat vertical side wall and shears the burr off cleanly at the root.
3. Side-by-Side Comparison: MIC-6 Diamond vs. Aluminum Oxide vs. Gummy Stones
| Stone Type | Abrasive & Core | Modern Hard Steel Cut | Best For |
|---|---|---|---|
| Salty Gold MIC-6 Diamond Stone | Monocrystalline diamond on poured MIC-6 cast aluminum | Fastest & cleanest; never dishes out | Uncoated stainless steel (Bauer, CCM, Step, True), home Sparx owners & bench goalpost repair |
| BladeMaster & Norton India Stones | Kiln-fired aluminum oxide | Moderate, forgiving feel; eventually wears | Traditionalists wanting a classic pro-shop hand hone on standard uncoated steel |
| Rubber / Gummy Stones & Leather Strops | Abrasive-infused elastomer or leather | Gentle polishing only (will not fix nicks) | Routine post-sharpening burr polishing on black/DLC-coated runners |
| Handheld V-Slot Sharpener | Angled ceramic rods | Emergency hollow scrape only | Road-trip emergency when a blade is completely blown and no sharpener is nearby |
4. Which Grit Should You Put in Your Hockey Bag?
- 140 Grit (Extra Coarse): Your emergency “goalpost & hallway concrete” rescue grit. Removes mushroomed metal fast between shifts so your skate won’t blow out on a crossover.
- 400 Grit (Coarse): Fast burr removal and minor nick cleanup on ultra-hard pro stainless steel.
- 600 Grit (Medium): The gold-standard all-around hockey honing grit—two feather-light passes after a Sparx or pro-shop sharpening leave a razor-clean edge.
- 1200 Grit (Fine): Mirror-grade Olympic finishing polish that reduces side-wall friction for maximum glide speed.
5. Crucial Caveat: Coated & Black Steel (Step Blacksteel, Bauer Pulse Ti, CCM Black)
If you skate on mirror-coated or dark DLC/titanium runners, any rigid mineral or coarse diamond stone rubbed broadly along the side of the runner will scratch the dark cosmetic coating. Follow the pro equipment manager rule:
- For everyday post-sharpening deburring on coated black steel, use a rubberized gummy stone or leather strop.
- Keep a 600/1200-grit flat diamond stone in your bag strictly for emergency mid-game goalpost nicks—where saving your edge for the 3rd period matters far more than a tiny cosmetic scuff right at the nick!
6. How to Use a Hockey Skate Burr Stone in 4 Steps (Without Rolling Your Edge)
- Wipe the runner dry: Dry both faces with a microfiber skate blade towel so moisture and ice crystals don’t clog the grit.
- Reference 100% flat on the side wall: Press the face of your stone completely flush against the flat vertical side of the steel—never tilted into the hollow and never dragged across the bottom of the blade!
- Make 1–2 feather-light passes: Glide smoothly from heel to toe using almost zero inward pressure—let the diamond or aluminum oxide abrasive shear the burr naturally.
- Repeat on the opposite face & wipe clean: Do 1–2 flat passes on the other side of the blade, wipe away metal dust, and test with your fingernail—both edges should feel crisp and snag-free.
Frequently Asked Questions
What does a skate stone or burr stone do for hockey skates?
A hockey skate stone (also called a burr stone or honing stone) knocks off microscopic folded steel shavings (“burrs”) left on the outer edges after machine sharpening and buffs down minor nicks from goalposts or arena concrete between sharpenings.
Are diamond skate stones better than aluminum oxide or gummy stones for hockey skates?
For uncoated stainless steel runners, a precision-cast MIC-6 aluminum diamond stone cuts faster on modern ultra-hard steel, never dishes into a curved groove, and stays 100% flat along the vertical side wall so it never rolls over your hollow edge. Soft rubber gummy stones are best reserved for protecting cosmetic dark coatings on black/DLC steel.
Can you use a regular skate stone on Step Blacksteel or Bauer Pulse Ti coated runners?
Do not rub coarse aluminum oxide or coarse diamond stones broadly across black or mirror-coated runners (like Step Blacksteel, Bauer Pulse Ti, or CCM XS Black), as abrasives will scratch the side coating. Use a rubberized stone or leather strop for routine deburring, and use a flat 600- or 1200-grit diamond plate only right on localized goalpost damage.
How do you properly use a hockey skate honing stone?
Dry the runner completely, place the flat face of the stone flush (90 degrees flat) against the flat outside face of the skate blade—never angled into the hollow—and slide smoothly from heel to toe for 1 to 2 light passes on both the inside and outside faces.
