My wife works for a vet and I obtained one of the staple guns. Actually had to use it two years ago after cutting my arm open on a job. I was amazed after using two staples on myself. If anyone watched that movie martian when he shot himself in the side and screamed in agony after each staple, well it didn't hurt. I was shocked at how it didn't hurt at all. Kinda funny how silly it was. i bring it with me on long hunts and keep it in the first aid kit when working as an emergency item if the chit hits the fan.
