THE SPARX GRINDING RING
THE HEART OF THE SPARX SHARPENING ECOSYSTEM
Each Sparx Grinding Ring is laser measured and inspected to ensure it meets our exacting standards. Unlike traditional stones where a hollow can differ slightly from sharpening to sharpening, a Sparx Grinding rings produces a precise hollow every time. Whether you want extreme grip for those tight turns, or that extra glide to beat your opponent to the puck, the Sparx Sharpener provides 16 different hollow options.
HOLLOW OPTIONS
TRADITIONAL RADIUS RINGS VS FIRE RINGS
SPARX RADIUS RINGS
TRADITIONAL HOLLOW
The Sparx Radius Rings produces the traditional hollows most commonly used in hockey, including the most popular 1/2” and 5/8” cuts. Choose from 12 different radius rings – from the deepest hollow for extreme grip (1/4”) to the flattest hollow for unmatched glide (1-3/4”).
SPARX FIRE RINGS
FLAT BOTTOM HOLLOW
Looking to get the grip you need with the benefit of extra glide? Our FIRE Ring hollows provide exactly what you are looking for – the best of both worlds. Available in four different cuts (3/8”, 1/2”, 5/8”, 3/4”) the FIRE ring is a re-imagined and optimized flat bottom hollow that provides improved glide while still maintain desired bite.
UNDERSTANDING RADIUS OF HOLLOW
Radius of Hollow is simply how deep the groove is that is cut into the skate blade from sharpening. The deeper the cut, the more grip the blade will have on the ice. The shallower the cut, the more glide the blade will have on the ice. A smaller Radius Ring (5/16”, 3/8”, 7/16”) will cut deeper into the blade creating more bite, while a larger Radius Ring (1-1/8”, 1”, 7/8”) will not cut as deep, creating more glide.
CHOOSING THE RIGHT RADIUS OF HOLLOW
Choosing the right hollow is a matter of personal preference, whether you want more bite or more glide. The most common Radius of Hollow is a 1/2”, which is what you will find in most retail settings. We recommend 1/2” for most youth players (less body weight) and then increasing the radius (9/16”, 5/8”) as the player gets larger.

FREQUENTLY ASKED QUESTIONS
How long does a Grinding Ring last?
On average, each Sparx Grinding Ring will sharpen approximately 60 pairs of
skates. This number is based on an average of three cycles per sharpen. If you
use less than three cycles per sharpen, you will get more pairs of skates per
ring and if use more than three cycles per sharpen you will get less pairs of
skates out of each ring.
How does the Grinding Ring know when it's out of sharpenings?
This information is stored on a microchip inside the Grinding Ring and is relayed to the Ring Life Status Bar on the Menu Pad.
Do you offer a Flat Bottom sharpening?
Yes! Our patented FIRE (Flat Inside Radius Edges) Ring produces a flat bottom hollow.
We also offer a FLAT Grinding Ring to help remove large gouges and nicks.
How do I know which Grinding Ring to choose?
While there are many options available, the most common grinding rings are the 1/2" and the 5/8" Radius Ring™. Through our testing, we have determined that a 1/2" Radius Ring is a great starting point for smaller, younger players. Many adult players skate on a 1/2" radius as well. We have, however, found that larger, heavier players actually do quite well on the 5/8" radius. A flatter radius, the 5/8" allows heavier players to sufficiently grab an edge for turning and stopping but provides great glide as more of the blade remains above the ice surface.
What is the difference between a Radius Ring™ and a FIRE Ring™?
The easiest answer is that the Radius Ring™ produces a traditional "radius of hollow" (ROH) sharpening. Unless you know you skate on a flat-bottom profile, you will likely want to choose the Radius Ring at checkout. The Radius Rings work for both player skates and goalie skates. The FIRE Ring™ produces a flat-bottom cut with radius edges. You can find more information on the Grinding Rings page or in this blog post.
