  • Best for: Skiers, snowboarders and field technicians needing rapid edge fixes
  • Not ideal for: Users requiring full-sized stones for complete re-profiling or workshop-only sharpening

Fast Edge Rescue – with extra-coarse, coarse and fine diamond grits

Extra-coarse grit removes damaged metal and reshapes nicks, coarse grit transforms a dull edge, and fine grit polishes to a sharp bevel. The sequence works on a compact scale suited to mini stones.

Quickly restore badly damaged edges and follow with refinement to achieve a usable, sharp finish during field repairs.

Speedy Sharpening – thanks to micronized monocrystalline diamond surface

Micronized monocrystalline diamonds create a highly abrasive, uniform surface that cuts more aggressively and consistently than conventional stones. The surface maintains abrasion over repeated use.

Sharpening sessions take less time, reducing maintenance between outings and keeping edges performance-ready with fewer passes.

No-Mess Maintenance – with dry or water sharpening, no oil required

Design allows use either dry or with water as a lubricant, eliminating the need for oil when working. Simpler maintenance keeps grit and residue straightforward to rinse away.

Field tuning becomes cleaner and faster, avoiding oil carry and simplifying post-sharpening cleanup.
