I saw two paracord bracelets that i liked, has everything, whistle or handcuff key, fish hook, fish string, flint! even a p51 attached, but as i was searching i came across a unique way to open a can with out a can opener or knife! if you think of it the only thing you have to do is break the seal to open the can right? so what do you need the can opener? watch the video and you'll say now why didn't i think of that! now grant it, whats inside could get a little dirt in it, but hey its better then no food right?
As for the ultimate paracord survival bracelet, check the two out, a little rich for my blood, but still freaking cool! JR
