Last Resort Straps offers survival bracelets which are made from Paracord. Paracord is a very high strength kernmantle rope which each stand has a test of 550 pounds. (the more you double the cord up the more it will be able to hold.) There are an endless use for paracord from rescuing yourself from a window if for instance your home is on fire, tying a tourniquet, to fixing a broken boot lace. These are only a few of the endless options.
