Grinding vs. Filing
Advantages of a ground edge vs. hand filing:
- Rotary grinding provides the sharpest edge, as it "throws"
the material across the edge. Compare this to sharpening an axe;
filing across the edge is much sharper than filing along the edge
(like most hand tuners).
- Files leave a rough surface finish. EdgeTune Pro II's fine #600
grit ceramic stone leaves a smooth, shiny finish with very slight
- Files remove significant edge material, reducing the life of
the ski/board. EdgeTune Pro II removes only a few thousandths of an
inch, saving edge material and extending the life of the
- The file or stone tends to "load up" or wear out quickly;
EdgeTune Pro II´s grinding stones have an outstanding life.
Dressing cleans and renews the grinding surface.
- The flat file or stone doesn´t conform to the side edge
curvature of modern shape skis/boards. They only make contact
on the very ends of the file or stone, making the tool ineffective;
EdgeTune™ Pro II utilizes a rotary cylinder that follows the exact
contour of the shaped edge.
- Hand filing is laborious and slow; EdgeTune™ Pro II is easy and
- Grinding work hardens the edge slightly, which improves
durability and stays sharper up 2X longer. This also saves time by reducing
