8. The Importance of Sanding your Fingers
Some climbers believe that sanding your fingers is important when climbing sharp or rough rock surfaces (i.e. granite, sandstone), where your fingers might develop burrs from climbing.
Tip: Use a file, to sand off the burrs until the skin is smooth again. This helps increase positive traction when climbing, and also helps form the finger callus into one single layer.
