The FIRE Ring flat bottom grinding ring for Sparx sharpeners, in four cuts from 3/8" to 3/4"
This is the grinding ring that does the work inside a Sparx skate sharpener. The ring is the consumable part: it spins against the blade, cuts the hollow into the steel and wears down a little with every pass. When it is finished you swap in a fresh one and keep sharpening at home.
The FIRE Ring is the Sparx flat bottom profile. A flat bottom cut leaves a flatter centre on the blade with bite on either edge, so glide and grip come out of the same sharpening instead of being traded against each other. Sparx describes the FIRE Ring as more forgiving than other flat bottom hollows, which on the ice means the edges feel less grabby the first time you get on them.
Four cuts are offered: 3/8", 1/2", 5/8" and 3/4". The cut sets how aggressive the edges feel. Shallower cuts release more easily and carry speed further; deeper cuts dig in harder for tighter turns and quicker stops. Most skaters already know the hollow they sharpen to, and the FIRE Ring numbering lines up with it.
It suits anyone running a Sparx sharpener at home who wants a flat bottom edge without sending skates out for a specialty cut.

Rings are chosen by cut, not by skate size. Pick the cut that matches the hollow you already sharpen to: shallower cuts such as 3/4" glide more, deeper cuts such as 3/8" bite harder. If you are not sure what your skates are cut to, our sharpening staff can tell you.
