To take care of the base edge(edge bevel) before sharpening the edge side.
The secret of manoeuverability and steering precision of skis and snowboards is a polished base edge, without rust, marking or too many scratches.
Long diamond files (150 x 20 mm) (6 '' x 3/4 '') and the Race bevel file are inserted into our file-guides where they can slide freely giving uniform wear over the entire surface of the diamond. Without freely sliding, wear appears in grooves with the undesirable effect of rounding the edge
