Interesting... but would they be strictly visual? I've had many poked into me and have never felt them... Of course, they were never used on me in order to cause discomfort... Can they be? Is it safe to do so? They're so small, would they be unfelt until they did actual damage to a nerve cell?

This is beyond my ken of knowledge.
