Nano Glass Skinfile

As a climber, you probably know the game of filing away excess calluses and skin. Sandpaper files are aggressive, wear out quickly and produce uneven results, especially at the edges of the skin, leading to flapping and other injuries.

The double-sided (fine and rough) KletterRetter NanoFile is made of etched glass, which is harder than files made of wood, sandpaper or plastic. The specially designed glass ensures even filing. After you’ve filed your skin, you can easily rinse the file with water and put it away for your next filing session.
