Tutorial: How to sharpen your own skis
You already know how to repair your bases and wax your skis like a pro… but what about sharpening? Often neglected, it is nevertheless essential to gain grip, stability and precision, especially on hard or icy snow.
Good news: sharpening your own skis at home is simple , economical, and very satisfying.
In this tutorial from Boutique Randonnée , we explain everything, step by step.
What is ski sharpening?
Sharpening your skis involves making the edges sharper . Sharp edges improve edge grip in turns, stability on hard snow, and overall ski control. Whether you're a casual skier or a steep slope enthusiast, proper sharpening makes all the difference.
The necessary equipment
Before you begin, make yourself comfortable. As with waxing, it is important to properly stabilize your skis using vises or trestles .
In terms of tools, you will need:
- a sharpening square
- a pair of pliers
- a file (steel or diamond)
- a brush (nylon or horsehair)
- a base edge
- a square eraser
Steps to successful sharpening
Step 1: Sharpen the edge on the sole side
Place your file in the base edge (89° angle), flat against the sole. Pull towards you while maintaining even pressure. Repeat the movement until you obtain a shiny edge, then brush to remove the filings.
Step 2: Sharpening the edge
Secure the file to the square using the clamp, then work the edge of the surface. The movement can be up and down or vice versa: choose the one that gives you the most control. If metal shavings appear, that's a good sign!
Step 3: Thorough cleaning
Once you have finished sharpening, thoroughly clean the edges with a brush or cloth. To test your work, lightly run your fingernail along the edge: if thin flakes of skin appear, the sharpening is effective.
Step 4: Reduce the thread
Sharpening creates a thin metallic thread along the edge. To remove it, use a diamond file , without applying too much pressure, first on the base side and then on the edge side. Repeat until you obtain a smooth, clean edge.
Tip: a little wax remover on the file improves glide and finish.
Step 5: De-pair for greater tolerance
Final touch: use an edge eraser to slightly round the tips. This will make your skis more forgiving and more enjoyable to ski on.
Which angle should I choose?
-
Recreational skiers : 90° angle for greater stability
- Sport/competition skiers : up to 87° for maximum grip on hard snow
