The Sidecut WC European File is a rectangular shaped file & was made specifically made for sharpening skis & boards. Preferred by many WC techs over many other files. Can also be used for base filing & fits in our Base Bevel Guides. Cut 11 is particularly good for new skis, hardened edges or removing edge quickly. Cut 14 is particularly good for finishing and/or everyday maintanence (14 teeth/cm). Cut 16 (16 teeth/cm) is used to finish & creates very smooth edges. Finish with a Diamond Stone or Ceramic Stone.
