I've managed to grind off the finger prints of several fingers while sharpening tools, both on a Tormek and japanese waterstones.
Today, while turning "hair sticks" (the inspiration from another thread in this group) with a bedan, I was dampening the vibration with the the index and middle finger of my left hand, left thumb on top of the bedan at the piece. Couple of hours later I come in for lunch and wash my hands. Soap is a great way to find injured tissue!
Learned
Rosewood is more abrasive than maple. Padouk is more abrasive than Cherry. Teak really is abrasive
Literally hands on turning maple can cause the turner to taste "maple".
fun stuff this woodworking thing.
