BBC:

Paper seems completely harmless, but anybody who has refilled a photocopier or thumbed too quickly through a book knows that this humble material harbours a deep, dark secret. Deployed properly, it can be a serious weapon: paper cuts are just the worst.

There isn’t a whole lot of scientific research effort directed at understanding the pain of paper cuts, probably because nobody would sign up for a randomised, controlled study that involved a researcher intentionally inflicting this kind of torture on study participants. But according to Dr. Hayley Goldbach, a resident physician in dermatology at UCLA, “we can use our knowledge of human anatomy to help us out here. It’s all a question of anatomy”.

Great look at the science behind what seem to be the most painful cuts of all.
