Troubleshooting: Why are my edges not sharp?
Skiers in the East often struggle with dull edges, while those in the West may face the issue less frequently. Regardless of location, dull edges are a challenge every skier will encounter eventually.
Are the sidewall and second edge pulled enough?
Most skis have a second edge, the thin metal layer between the sidewall material and the ski, made from a distinct type of metal, Titanal. Excess material will block your file or machine from cutting the edge smoothly. This may even cause your 3-degree edge to turn into a 2-degree edge. Use a sidewall planer to address this issue. (For a tutorial, refer to the Nov. 28, 2023, eBlast.)
Are the skis brand new or recently machined?
Machines sometimes leave the edge hardened, making it difficult to file effectively. Use a coarse diamond file with your guide to cut through this layer before filing again.
Is your file dull?
Files need to be replaced more often than you might expect. Consider using the World Cup (WC) File Chrome for sharper, more durable results.
Do you have a 3-degree file guide?
A 87-degree guide, also called a “3” is essential for creating sharp edges suitable for racing. A 2-degree guide won’t provide enough grip. I once spent a month using a TriOne machine set to 2 degrees and experienced a lack of grip on the slopes. If you’re using a machine, ensure it is calibrated occasionally to maintain accuracy.
Don’t overuse your coarse diamond file.
Instead of making countless passes with a coarse diamond file, try a few passes with a sharp file. Follow up with a fine or extra-fine diamond file on the base edge and side edge, always finishing on the side edge.
A last-ditch effort:
Finish your edge with a light pass using a hard Arkansas stone. This step gives the edge an aggressive finish, especially if you slightly increase the angle on your pass.
