Why? Your fingertips are very. They're built to serve as the means by which your brain processes your sense of. They can feel, pain, and easily. There are more nerve fibers (called nociceptors) per square inch in your fingertips than most other areas of your body. When you get a paper cut, the paper slices through these nerve fibers, resulting in many pain signals being sent to your brain. If that wasn't bad enough, you'll notice after a paper cut that you can't just stop using your hands until it heals. You need to use your hands and, as you do so, your skin moves and the wound gets pressed and pulled upon, which delays healing and renews the pain you feel each time it happens. The typical of paper cuts explains why a paper cut on your fingertip hurts more than a similar cut on your belly or leg. However, a paper cut tends to hurt more than a different kind of cut, like from a knife, on your fingertip.

Goldback says, вIt would probably also hurt a lot if you got a paper cut on your face or in your genitals, if you can imagine that вFingertips are how we explore the world, how we do small delicate tasks.

As if that wasnвt horrible enough, he adds: вPaper leaves behind chemical particles, irritating the wound. вBecause the wounds are shallow, they donвt bleed or clot very much.
