   What is FBV

Folks, this type of sharpening has hit the market like a storm. No-Icing Sports was proud to be the first in America to offer this new method to our local customers, and to our internet customers throughout the country and world. Unlike the conventional sharpening that puts a hollow between two edges, the FBV is a totally different way to sharpen and shape an ice skate blade.


With a conventional sharpening, you have to choose between grip/bite and speed, you can't have best of both, you have to lose performance in one aspect to gain in another. However with the FBV, you can have both maximum bite (when you need it) but also maximum glide (when you need it). By maximum glide we mean no drag from edges, just pure speed like an Olympic Speed Skater.

The Flat Bottom V or FBV skate sharpening is very different than what you are use to getting on your skates. The FBV has almost a totally flat bottom and the edges are just at the tips, slightly offset from the flat. How it works is the large flat contact area prevents the blade from sinking into the ice. So when gliding in your stride, you are on the flat area only. This has little drag which gives you awesome speed and endurance. However, when you lean the skates to turn or stop, then the edges will dig in perfectly, giving you great turning or stopping. For example, you can achieve the glide similar to a speed skater yet at the same time, have any amount of grip you want and prefer. We offer choices for those who like extreme grip, all the way to those who prefer little grip. An FBV is available for every type skater.

The Flat Bottom V has virtually zero getting use to time. First timers in a matter of minutes will easily adapt to this type sharpening and soon be reaping the rewards of super speed, great turning, and increased endurance.

Here's what one customer had to say about the FBV sharpening:

"I just got off the ice after my first skate on the FBV blades. This is the only way to describe it: "The Holy Grail of Sharpening". I'm speechless about how these blades perform. More glide than my 5/8ths and way way more bite. I seriously could not get an edge to lose grip even after the ice got trashed at the end of stick time...and I started trying was a game to see if I could get a damn edge to lose rip....nope! You can feel the enhanced glide and then the moment you roll on edge its like super glued to the ice..its crazy. I don't know if I have ever skated better Bob - seriously. I'll never go back to "old" sharpening again."

Getting an FBV on your skates does not alter your Rocker radius at all, it does not take off any more steel than a regular sharpening, and if you are ever in a bind for a sharpening, it can easily be sharpened over with a hollow by any sharpener.

We offer many different FBV's, all have great speed. We'll select the one that gives you the bite that's appropriate for your profile.

Try it, you'll never go back to a regular sharpening again!

Blackstone Sports is the only authentic FBV. Don't be fooled by the imposter versions that are out there. They are not the real FBV. They are poor attempts by the other skate sharpening machine manufactures to trick skaters into believing their version is the FBV. They are not. If they are called FireRing or BFD, they are not the real FBV.  They are nothing more than a decades old shelved sharpening method that was pulled out of the cobwebs when FBV hit the market.  Also beware, if you go into a shop and ask if they do FBV, many will lie to you, say they do, and give you the imposter instead.  This is very common practice in our area and customers from everywhere tell us they got a crappy FBV at another store but in reality, they got the poor copycat, not a real FBV. The FBV is a superior design.  But you can decide for yourself, go get one of the imposter sharpenings, skate on it, then get a real FBV and tell us which you like better.

Note: This is just a basic guide we developed after feedback from skaters. There are a lot of online guides you'll find, they seem to change every 6 months and are not very accurate. We have 10,000+ skating on FBVs, our assessment is pretty spot on based on real feedback.
