....in the 'Stone Love' video (the Cresciano one), when he's seen what looks like buffing his fingers in the rented apartment?
I was wondering if he and others I've half-seen in other vid.s use an emery board to desensitize the skin on their finger tips. I think Ben Moon is seen doing a similar thing in 'Stick It'.
Here was me thinking he had either spectacularly maintained nails, or figured out how to climb solidly for a week long trip
without getting super-sensitive tips by the end of it!
