"The depth of the wound is perfect for exposing and exciting the nerve fibers of the skin without damaging them the way a deeper, more destructive injury can severely damage the nerve fibers impairing their ability to communicate pain," Neal adds. "With a paper cut, the nerve fibers are lit, and they are fully operational."
