YT "Some of the most infuriating and stabbing pain is caused by nothing but a thin sheet of paper. Scientific American editor Ferris Jabr explains why the page of a book can sometimes cause more anguish than a blade."

Copper still resents us for switching to zinc to make pennies.
And paper is definitely not smooth edged, every time I get a paper cut time seems to slow down and I can swear I feel every bump like a tiny buzz saw ripping through my skin.

You also gotta consider that paper burns the surface with friction before breaking the surface of the skin. However I think the culprit is still location, location, location. I can get scrapes around all areas of my skin, but finger tips where most sensory nerves are clustered are generally cut by something blunt that I have pressed into hard enough.
