Parachute cord is also known as paracord and is a lightweight nylon kernmantle rope. Kernmantle rope has a core (kern) of long twisted fibers in the center, with a braided outer sheath or mantle of woven fibers. The braided sheath has a high number of interwoven strands for its size, giving it a relatively smooth texture.
Originally used in the suspension lines of US parachutes during World War II. Once in the field, paratroopers found this cord useful for many other tasks. It is now used as a general purpose utility cord by both military personnel and civilians. Despite the historic association of para-ropes with Airbourne units, virtually all US units have access to the cord. It is used in almost any situation where light cordage is needed.
Typical uses include attaching equipment to harnesses, as dummy cords to avoid losing small or important items, tying rucksacks to vehicle racks, securing camouflage nets to trees or vehicles, and so forth. When threaded with beads, paracord may be used as a pace counter to estimate ground covered by foot. The yarns of the core (commonly referred to as "the guts") can also be removed when finer string is needed, for instance as sewing thread to repair gear, or to be used as fishing line in a survival situation. Ends of the cord are almost always melted and crimped to prevent fraying.
The all-nylon construction makes paracord strong.
Paracord is durable and has a smooth texture. Paracord Jewellery includes 'Survival bracelets', lanyard and watchbands, as well as key fobs.
