FKSKS 100x20mm HSX Supersteel File X-Fine - 3501

FKSKS 100x20mm HSX Supersteel File — X-Fine | Ultra-Precise Edge Finishing

When a sharp edge isn't enough and you need a polished, race-ready finish, the X-Fine HSX Supersteel file is your final step. Engineered with High-Speed Xtra hard steel, it delivers the ultra-fine cut needed to bring ski and snowboard edges to their smoothest, most precise condition.

Why tuners choose the X-Fine:

• Extra-fine grit — ideal for finishing and polishing after initial sharpening with a coarser file
• Near tungsten carbide cutting power — exceptional hardness and precision at a lower cost
• 100x20mm backshop format — designed for bench tuning and professional use
• Compatible with standard 100mm file holders and guides — fits most major brand holders
• Long-lasting reliability — maintains high functionality even as initial sharpness gradually diminishes

Perfect for: race technicians who need a flawless edge finish before race day, professional tuning shops doing multi-step edge work, and advanced skiers who demand the smoothest possible edge.
