Fingertips and hands have significantly more nociceptors (nerve fibers) per square millimeter than most of the rest of your body, such as your legs, arms, stomach area, etc. This ends up making cuts on your fingertips feel significantly more painful than cuts elsewhere, even when they are produced by paper or similar objects.
