For an optimal sharpening result there are 5 different grades of self-adhesive lapp film on a specially extruded aluminium triangle.
The length of the triangle is 25 cm.
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.
The standard triangle has 3 grades glued onto it, namely 40 (blue), 30 (green) and 3 (pink) micron. Two additional grades are available: 9 (light blue) and 12 (yellow) micron.
Directions of use
Place the skates in a jig. Start with moving the blue side of the triangle back and forth 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 decreases again after 1 minute, end with the pink side. When there is no more friction, the job is finished. This process will take approximately 3 to 5 minutes in total.
For an optimum result look at the gliding surface of the skate. If you see a “mirror”, the result is optimal. If not, simply repeat the last (pink) or the second-last (green) procedure.
