The sharpness of your skates can affect both speed and agility, so you'll need properly sharpened skates for top performance on the ice. You can manually sharpen your skates with the right tools, but doing a good job requires a precise level of skill and technique. Skate blades have two ridges, and you must sharpen both to the same level for proper performance.
Put each skate into a sharpening jig and tighten the front support first. You must place skates in the same position each time in order to achieve the same cut.
Turn the back blade brackets until they are tight, then tighten the front blade brackets. The skates should fit snugly against the plastic restraining bar. Set up the skates so that the blades are parallel to one another and level on top.
Place the sharpening jig between your legs and sit down. This allows you to keep the jig steady while sharpening the blades. Use your flat file and begin at the toe or heel and move it across the blade in a diagonal motion. The file should always remain perpendicular to the blade when sharpening.
Run the flat file across a blade in one direction 15 to 20 times and then repeat in the opposite direction. Do the same for the other skate.
Use a burr stone to wipe away any metal fillings, and then wipe off the sharpened blades with a towel.
