For an optimal sharpening result there are 6 different grades of self-adhesive lapp film on a specially extruded aluminium triangle.
The length of the triangle is 25 cms.
The micro aluminium oxide gives the edge a very shiny surface.
The aluminium triangle comes complete with 3 different polishing strips. The strips can be reordered separately or in a set of 3 (blue,green,pink).
3 Grades are standard glued to the triangle. Namely 40 (blue), 30 (green) and 3(pink) Micron. 2 Additional grades are available. 9 (light blue) and 12 (yellow) Micron.
Directions of use: Put the skates in a jig. Start with moving the blue side of the triangle backwards and forwards slowly over the runners. Use the entire surface of the 3M abrasive strip during this action. When the friction decreases during the polishing (after approx. 1 minute) change over to the green side. When the resistance declines again after 1 minute, end with the pink side. When there is no friction one is ready. This process will take approxomatily 3 to 5 minutes in total. To make sure that the result is optimal you have to look at the gliding surface of the skate. If you see a “mirror” the result is optimal. If not, do the last (pink) or the second last (green) treatment again.
