Fk Sks 100mm Pro Tungsten Carbide File; For Ski, Snowboard

This multi-tooth tungsten carbide file will even cut case hardened edges (rock dings) and stay sharp. Carbide blades are 5/8 inch x 1/4 inch segments and are mounted on an aluminum backing plate. Sharpest, longest lasting file you can buy for tuning your ski edges. Fast, efficient tool for backshop work. This is the pro model comes with 4 (vs. only 2) cutting surface segments. Fits all edge tools that accept 100mm files.
This file is mostly useful to repair ski edges from rock dings. The act of skiing and hitting a rock with your skis not only damages and deforms the metal edge, the impact also tempers (hardens) the edge steel which makes filing the damaged area resistant to regular steel files. This is where a tungsten carbide file is necessary to repair the damaged edge area.
