Edge tools (steel edges/side edge)

Edge tools maintain the correct angle when sharpening steel edges. The foundation for sharp and precise edges. Read more further down the page.

How edge tools work

Edge tools are used to sharpen the steel edges of skis and snowboards at the correct angle. They act as a guide that keeps files and stones in place, so you get an even and consistent result every time. With a good edge tool, sharpening becomes easier and the edges sharper.

Benefits of edge tools

• Maintains an exact sharpening angle – for consistent results.
• Fits both files and diamond stones.
• Can be used by both beginners and professionals.
• Provides better grip on hard snow and ice.

How to use edge tools

1. Place the ski in a ski holder so that the steel edges are easy to reach.
2. Attach the file or stone to the edge tool.
3. Draw the tool in the direction of the ski with even pressure.
4. Start with a file to shape the edge, finish with stones for polishing.

Tips for best results

• Start with a coarser file and then move to finer file/stone.
• Always work in the direction of the ski, not back and forth.
• Have separate stones for different coarseness for the best finish.
• Remember to polish off all burrs after sharpening.

FAQ – Common questions about edge tools

Do I need an edge tool to sharpen?
Yes, without a tool it's difficult to maintain the correct angle. The edge tool provides precision and saves time.

Can I use both files and stones in the same tool?
Yes, most edge tools are made to fit both.

What angle should I choose?
Common is 88–90 degrees, but it depends on the discipline. A steeper angle (e.g., 87) provides more grip but makes the edge more sensitive.

Are edge tools only for competitive skiers?
No, even recreational skiers benefit greatly from them. Sharp steel edges provide better control and safety.
