Files

How files work

The file is the foundation of all sharpening of steel edges. It is used to remove material, shape the angle, and restore sharp edges when they have become worn. Without a good file, it becomes difficult to give the edges the right sharpness, and thereby poorer grip on hard snow and ice.

Different types of files

• Coarse file – removes a lot of material quickly, used to repair really worn or damaged edges. Or to initially set the correct angle.
• Medium file – the standard file mostly used for regular sharpening.
• Fine file – provides a smoother surface and is often used before moving on to the stone.
• Special files – small files for details, such as at transitions or precision sharpening.

How to use files

1. Place the ski in a stable ski holder so that you can access the steel edges properly.
2. Use an angle guide to ensure the correct sharpening angle.
3. Make long strokes with the file in the direction of the ski – avoid short, jerky movements.
4. Finish with a finer file and then the stone for polishing.

Tips for best results

• Always use an angle guide to maintain an even and correct sharpening.
• Start with a coarser file and move to a finer one for a cleaner result.
• Always combine files with stones to remove burrs and polish the edges.
• Have several files – worn files give uneven sharpening.

FAQ – Common questions about files

What is the difference between a file and a stone?
The file removes material and shapes the angle on the steel edges. The stone is used afterwards to polish and remove burrs.

Which file do I need as a recreational user?
A medium file is sufficient for regular sharpening. If you want to be more precise, complement with a fine file and stones.

How long does a file last?
It depends on how often you sharpen, but files wear out over time. Replace when you notice it no longer removes material effectively.

Can I sharpen the edges without an angle guide?
It's possible, but the risk is high that the angle will be uneven. A guide makes the work both easier and more accurate.
