Nate Valdez is good with fingers. Take, for example, his care when removing jewelry from them. First he coats a finger with wax. Then he ties a string around its base and wiggles it up slowly behind the ring it's wearing until the ring slinks off the tip at the fingernail. He calls this "the string technique," and it is the best way to get these things off a corpse without ripping the skin off with them. Despite his caution, there will still be little flakes of flesh on the table, from where the dermis layer has separated from the subcutaneous tissue because the body has been dehydrated by its owner's passing.
