Paracord (also parachutecord or 550 cord) is a lightweight nylon cord 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 has an interior core made up of 7 individually twisted strands covered by a woven exterior sheath. It is now used as a general purpose utility cord by both military personnel and civilians. This versatile cord was even used by astronauts during STS-82, the twenty-second Space Shuttlemission, to repair the Hubble Space Telescope!
While the U.S. military has no overall diameter requirements in its specifications, in the field 550 cord typically measures 5⁄32 inches (4 mm) in diameter. It can be found in several colors schemes. When the inner strands are removed from the woven exterior the individual strands can be used as accessory cord or the outer sheath as a tubular webbing.The all-nylon construction makes paracord fairly elastic; depending on the application this can be either an asset or a disadvantage. When it comes to untying stubborn knots it’s a definitely a disadvantage.
Our love for paracord brought us to create the Fish Bone Knotless Gear Tie! Our products were designed and developed specifically with this versatile cord in mind (and yes, they’ll work even if it’s not paracord).
