Jan:
I should have been clearer… that’s exactly when it happens to me. I really just use it for holding small screws that I need to grab with either a screw holder or tweezers. Otherwise, I just use it to daub a little oil or grease off of something. I either use gloves or finger cots when I work. Unfortunately, they become a problem when replacing mainsprings – rubber and winding don’t go well together. 
Thanks,
Tom
