Surrounded by different products I find myself putting together a variety of Survival Kits. The Survival Necklace was an idea for a kit that would be virtually impossible to be separated from. It is not in your pockets, in your backpack, or in your vehicle, it is put around your neck. It might be an item you slip on when you are going scouting around your camp and want something basic with you, or you are in a boat and you want something in case the boat flips, or perhaps you just like that macho cave man necklace/bling look. In any case this was assembled with the understanding you may be immersed in water while wearing it so it must be able to withstand a dunking. Again, what you would build is up to you, I just tried to build it durable and simple.
It is centered around some basic categories, a good cutting tool, firestarting, navigation, signaling both visually with a reflector and by sound with a whistle. I used a leather necklace, it could have been 550 cord but leather gives me the ability to tie the knife to a pole with wet leather and once it dries it will tighten up. The knife is an Ansa Knife made by Charlie Davis from old files. These knives are very sharp and sturdy and could be replaced with a folder like a 5 blade military knife but I used the Anza because I wanted something special.The black whistle is a UST jet scream a powerful sturdy pealess whistle, the compass a Sun Mini Comp compass an excellent micro orienteering compass, the firesteel a 1/4" X 2.5" ferrocerium which can be scraped using the knife, the matches are in an orange Exotac waterproof aluminum carrier and the signal mirror is an Adventure Medical Rescue Flash. The kit you build could be entirely different, but only use items you have tested and are confident with. The Rock, that is just basic Caveman gear and not attached to the necklace.
