Hockey Skate Sharpening Service In The Downriver Detroit Area

Skate Surgeons is the only SPARX Professional Pro Shop in southeast Michigan.  If you are looking for a competitive edge, no other machine or human sharpener will deliver the accuracy and consistency that SPARX can!  If you want the MAXIMUM amount of GRIP from your skate EDGE, you have found the solution!

We were one of the first pro shops in the country to get the SPARX Professional skate sharpening machines and we have sharpened thousands of pairs of skates on them since.  We have put our sharpening up against some of the best and most experienced sharpeners in the area multiple times and our edges always come out more level and the skate has a smoother finish.  Those so-called “CERTIFIED” skate sharpening programs that some pro shops boast are an outdated gimmick at this point.

Great skate sharpening is no longer a mystery.  While it is still important to understand how to properly sharpen skates and the principles of skate blade radius, SPARX has created a machine that takes nearly all the guesswork and human error out of the process.  SPARX machines are designed to do one thing perfectly and that is to deliver level edges with a smooth finish and it does that fantastically.

There is nothing to be skeptical about with SPARX!  Nearly every NHL team, many AHL, ECHL, college and junior team’s are using SPARX!


The edge checker measures skate blade level to within .001 (one thousandth) of an inch (less than the thickness of a post-it note) and not detectable by the human eye!    A sharpening that is off by .004 or more will be noticeable by most skaters.  The SPARX edge checker is one of the most accurate checkers on the market.  If you have had your skates sharpened elsewhere, feel free to have a complimentary edge check done in our shop.  We will quickly be able to confirm if your skate runners have been sharpened properly or not.  The image below shows a blade that is off by .001 which is within normal tolerance.


ROH – The most common cut, ROH (Radius of Hollow), is essentially an arc of a circle. Grip and glide are determined by the radius of that circle and typically range from a 3/8″ radius to 1 1/2″ radius, with 3/8″ providing the greatest amount of “bite”

FIRE™ (Sparx)/Flat Bottom BFD™ (Blademaster)- As you can see in the graphic, this shape provides the radius edges familiar to those accustomed to ROH and also includes a flat bottom which limits the edges from sinking into the ice as deeply as they would on a traditional ROH. This combination increases glide while still maintaining enough “bite” to make sharp turns and stop short.

FBV™ – Blackstone’s Flat-Bottom-V – Similar to the Flat Bottom BFD/FIRE, but there is one noteworthy difference. The Flat-bottom-V has all straight edges as opposed to the radius edges of the FIRE Ring.
While not limited to these 3, these are the most common shapes used by hockey players. It is also worth noting that while you will find players of all levels that prefer one shape over the others, there is no scientific evidence proving that one is better than the other. That said, we don’t need science to know what feels best to us and this is why we encourage players to experiment.

The Depth (ROH) – As mentioned above, the radius of hollow is based on a circle. The smaller that circle (e.g. 3/8″ radius), the deeper the hollow will be, hence providing the skater with greater grip or bite. The larger the circle (e.g. 1 1/2″ radius) the shallower the hollow will be, hence providing great glide. Typically you can increase in size by 1/16 of an inch from 3/8″ to 1 1/2″ (3/8″, 7/16″, 1/2″, 9/16″, 5/8″, 11/16″, 3/4″, 13/16″, 7/8″, 15/16″, 1″, etc.). As you can see, this provides just a ton of opportunity to try different options and find one where you feel you can skate at your fastest and still feel confident that you can stop short, start quickly and make sharp turns.

Generally speaking, flat bottom options are offered in a much smaller range. There are likely 2 primary reasons for this; 1) most people prefer (or are satisfied with) one of just a few options and 2) the overhead for a shop owner to offer a wide range of flat bottom options is more prohibitive.

FIRE™ – The Sparx FIRE Rings are offered in 3/8, 1/2, 5/8 & 3/4 – these numbers represent the ROH associated with the radiused inside edges of the FIRE Ring. As such the grip-to-glide relationships are relatively the same as ROH with the 3/8 FIRE providing the greatest amount of grip and the 3/4 FIRE providing the greatest amount of glide.

Flat Bottom BFD™ is offered 3 options; X6 (similar bite to 3/8″ ROH), X7 (similar bite to 1/2″ ROH) and X8 (similar bite to 3/4″ ROH). Not surprisingly, the most common of the 3 options is the middle-of-the-road X7.

FBV™ – While it is possible to try many different FBV options, typically you’ll find that shops offering FBV sharpening offer four options 90/50, 90/75, 100/50, 100/75. These numbers represent -thousandths of an inch (width of the flat part of the blade) / ten-millionths of an inch (the height of the fang) -, so we are dealing with very small numbers. To provide some context, here is how these popular FBV sizes relate to traditional ROH.

90/50 = 3/4″ ROH (more glide)

90/75 = 5/8″ ROH

100/50 = 1/2″ ROH

100/75 = 3/8″ ROH (more grip)
