Rotary Grinding vs. Filing
Typical do it yourself edge tuning systems utilize
a file/diamond stone with a bevel guide, which have problems:
- 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's fine #600
grit ceramic stone leaves a smooth, shiny finish with very slight
striations.
- Files remove significant edge material, reducing the life of
the ski/board. EdgeTune Pro removes only a few thousandths of an
inch, saving edge material and extending the life of the
skis/boards.
- The file or stone tends to "load up" or wear out quickly;
EdgeTune Pro´s grinding stones have an outstanding life.
- 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 utilizes a rotary cylinder that follows the exact
contour of the shaped edge.
- Hand filing is laborious and slow; EdgeTune™ Pro is easy and
fast.
