This was found over at Armament Services International, a place that deals in NFA-regulated firearms. It is also the most awesome first aid kit ever invented.
Although probably not if you, you know, cut yourself on something. Then it’s less awesome, although it would still be pretty cool and remain fun to shoot, especially if you weren’t cut that seriously.
Then you could use the hot brass to sterilize the cut, rub some sand into and keep going.
