Grinding wheels

Skate steel varies in quality and type. Therefore it is important to use a really good grinding wheel together with a good diamond dresser.
In general, a finer grinding wheel will give a more shiny result, and a coarser grinding wheel will work faster and be more effective.

Diamond dressers

When sharpening, successive wear of the grinding wheel will cause it to become dull. To get is sharp, it needs to be dressed with a diamond.
The way to do this is by having a diamond edge move over the surface of the rotating grinding wheel. Then new sharpening grit gets exposed.

Hand hones

When a skate has been sharpened to get sharp edges underneath, burrs will arise on each side of the skate blade.
Use a hone to remove them by pulling it along the sides. Then you will have perfect sharpness!
