How do you sharpen ski and snowboard edges?

Published in Ski/Snowboard Tuning 3 mins read

Sharpening ski and snowboard edges involves using specialized tools and techniques to restore the crispness needed for optimal performance on the slopes. Here's a breakdown of the process:

Understanding Edge Angles

Before you begin, it's important to understand edge angles. Edges have two angles:

  • Base Edge Angle: This is the angle of the edge relative to the base of the ski or snowboard. A more acute angle (e.g., 0.5° or 1°) provides better grip.
  • Side Edge Angle: This is the angle of the edge relative to the sidewall. Typical angles range from 87° to 90°. A steeper angle (e.g., 87°) results in a more aggressive edge hold.

Tools You'll Need

  • Edge Tuner/File Guide: This tool holds the file at the desired angle.
  • File(s): A coarse file for removing damage and a fine file for creating a sharp edge. Diamond stones are also useful for polishing.
  • Gummy Stone: Used for deburring the edges after sharpening.
  • Vise: To hold the ski or snowboard securely.
  • Gloves: To protect your hands.
  • Marker: To mark the desired angle on your file guide.

Sharpening Procedure

Here's a step-by-step guide to sharpening your edges:

  1. Secure the Ski or Snowboard: Mount the ski or snowboard in the vise, base up. Ensure it's stable and secure.

  2. Sharpen the Base Edge:

    • Set the file guide to your desired base edge angle (e.g., 0.5° or 1°).
    • Align the file guide to the base edge.
    • Using long, smooth strokes, run the file along the base edge from tip to tail, applying consistent pressure. Overlap each stroke slightly. The reference short answer provides a good starting point on stroke direction: "starting up at the widest part of the nose (front). Using long, smooth strokes, run the file from the widest part of the nose toward the widest part of the tail."
    • Repeat until you achieve a consistent, sharp edge.

  3. Sharpen the Side Edge:

    • Mount the ski or snowboard in the vise, side up.
    • Set the file guide to your desired side edge angle (e.g., 88° or 89°).
    • Run the file along the side edge from tip to tail, applying consistent pressure.
    • Overlap each stroke slightly and work with smooth, even strokes.

  4. Deburr the Edges:

    • Use a gummy stone to remove any burrs or imperfections from the edges. This helps prevent catching.
    • Run the gummy stone along both the base and side edges.

  5. Polish the Edges (Optional):

    • Use a diamond stone to polish the edges for an even smoother finish.
    • This helps to reduce friction and improve glide.

Tips for Success

  • Consistent Pressure: Maintain consistent pressure throughout the sharpening process for even results.
  • Sharp Files: Use sharp files for efficient sharpening. Replace dull files as needed.
  • Proper Angle: Select the appropriate edge angles based on your skill level and the type of terrain you typically ride.
  • Practice: Sharpening takes practice. Don't be discouraged if your first attempts aren't perfect.
  • Safety: Always wear gloves to protect your hands.
  • Consider Professional Tuning: If you're not comfortable sharpening your own edges, consider taking your skis or snowboard to a professional tuner.
