Also this may sound stupid, but a friend of mine pointed out how helpful it would've been when he split open his thigh (Don't ask...Lol) if he had some Duct Tape. So I got to thinking and looked at my Roll of Gorilla Glue Duct Tape. That sticks damned near well to flesh...so I am gonna throw a roll into my FAK in my car's trunk. Might come in handy for holding together a big wound for a bit.
I hope you put some gauze between the wound and the duct-tape..
Anyhow, Duct-tape is a great addition for any FAK.
