i should probably get one of these
i used to chew on my nails really aggressively because of anxiety which led to disgusting nails and bloody fingers
i started flipping my knife with my left hand while i did things with my right and i no longer bite my nails
a problem is that when i flip the knife i do it aggressively, such as i did with the biting of my nails so the back of my hand is all bruised and cut from a few misses
i feel like a fidget spinner or maybe even a rubik's cube might be the solution to this
