Kunzmann Alu Oxide Stone 100x20mm Angle File Guides ( 3250)
This Kunzmann Alu Oxide Stone 100x20mm Angle File Guides ( 3250) is ideal for de-burring and smoothing the edge of skis or snowboard edge.
It is used with the File Angle guides found here as these are 4″ (100mm) long and can be clamped to the file guide.
It is particularly used for getting through case hardened edges where the ski has hit a rock at speed.
Case hardened edges can be seen by their discoloured marks along the edges. Generally they are blue, red or purple colour.
To cut through the case hardened area, clamp the stone in your file guide and do complete passes along the Ski edge and repeat with the stone until the discolouration is removed. Then use a regular steel file to go over it again.
Then use a diamond file to give it a nice clean, sharp finish.
If you are having trouble with your normal file cutting your Ski and Snowboard edges then go over the edges with this stone first.
This will deposit some of the stone on the edges and will help the steel file cut the Ski or Snowboard edges much better.
