Make a Tourniquet
Life in the great outdoors is not for the faint of heart. There are nicks, bumps, bruises, gashes, and threatening injuries. Among its many uses, survival bracelet material can be unwound and made into a tourniquet to limit blood loss.
True story: James Little was hit in the leg with shrapnel during military duty in Iraq. Unable to flee to safety, he unwove one of the two survival bracelets he was wearing and tied it around his wounds to stop the bleeding. With material from the other bracelet, Little tied up nearby rubble and used it as cover [source: Ciccone].
