i cut my thumb and part of the nail. it bled for over four hours so i went to the Emergency room. sat there for another hour and it had stopped bleeding then, so they ended up only wrapping my thumb like I was a mummy. Since the nerves were cut a bit, i bought a metal guard that slips over the finger and that helped me work better. it took over two months to be able to stop wearing the guard. all is well now.
irritating part was that the long ruler i was using had a plastic guard on one side and i was using the other side!!
