Not only have I sewn my fingers several times, I once ran the rotary blade between my thumb nail and my thunb! Talk about a painful situation! At the hospital they must have asked a dozen times HOW I managed to cut my thumb in such a manner and worse....they were wondering how to sew it up! They finally sewed on each side of the thumb nail and butterflied the nail tip down towards the back of my thumb. Talk about painful! You can bet I'm much more observant and careful now!
