Description

Having trouble getting your files to bite/cut? It could be that the steel is hard in places down the edge. The Kunzmann Alum Oxide Stone is designed to soften the edge making it easier to grind the edge and easier to sharpen the ski. Just place the stone in your file guide or can be used by free hand, then run the stone up and down the edge until filing becomes easier again.

Features:

• For use to eliminate hardening of ski edges.
• Aluminum-oxide stone fits all Kunzmann sharpeners with 100 mm file.
• Size 100x25x4.2mm.
