Lately I have gotten a few emails asking me about parachute cord.As luck would have it I actually know quite a lot about the stuff.
I am a graduate of the U.S. Army Parachute Riggers course,and served as a Rigger for 3 years.
I have used "550" cord as it is commonly called many times but do not carry any with me as I travel around the USA. The reason being,is that I find so much discarded nylon bailing twine laying around that I'm in the habit of using that.
When I'm traveling to Asia or south America, I do carry about 50 feet of the cord as part of my survival gear.
Many of My friends over at BCUSA.com are into the making of bracelets and belts to wear into the field. these items can be unwound and will provide you with a pretty good supply of cord in an emergency situation.
550 cord has as many uses as your imagination can conjure up. One application of parachute cord I can remember reading about lately, is the story of a USAF Para rescue unit that had to ditch in the ocean during a storm , at night. The crewmen tied them selves together with 550 to prevent being separated in the dark. Good idea.
Below you will find a little info about the different types of 550 cord and it uses.
I hope you find it informative .

Parachute cord (also paracord or 550 cord) is a lightweight nylon kernmantle rope 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. This versatile cord was even used by astronauts during STS-82, the second Space Shuttle mission to repair the Hubble Space Telescope.
The braided sheath has a high number of interwoven strands for its size, giving it a relatively smooth texture. The all nylon construction makes paracord fairly elastic; depending on the application this can be either an asset or a liability.
Despite the historic association of paracord with Airborne 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 fishing line in a survival situation. The nylon sheath is often used alone, the yarn in the core removed, when a thinner or less elastic cord is needed. Ends of the cord are almost always melted and crimped to prevent fraying.
In addition to purely utility functions, paracord can be used to fashion knotted or braided bracelets, lanyards, belts, and other decorative items. 550 Cord is used by many US military members as a bracelet signifying deployment to the Central Command Area of Responsibility, typically countries in the Middle East. It is also worn in remembrance of POW/MIA service members during National conflict. It is fashioned by using three equal lengths of cord and weaving them together to make a bracelet that is then secured with a looped end and a button from the Desert Camouflage Uniform. The bracelet is commonly seen among those serving in the Middle East.
TYPES:US Military issue paracord is specified by MIL-C-5040H in six types: I, IA, II, IIA, III, IV.Types IA and IIA are composed solely of a sheath without a core. Type III, a type commonly found in use, is nominally rated with a minimum breaking strength of 550 pounds, thus the GI Name of "550 cord".
The US military specification for paracord outlines a number of parameters to which the final product must conform. Although it contains specific denier figures for the sheath strands and inner yarns, there are no overall diameter requirements for the cord itself. Below is a table of selected elements from the specification.
TYPE AND MINIMUM BREAKING STRENGTH:I 95 lb (43 kg)
IA 100 lb (45 kg)
II 400 lb (181 kg)
IIA 225 lb (102 kg)
III 550 lb (249 kg)
IV 750 lb (340 kg)
The same properties which soldiers appreciate in paracord are also useful in civilian applications. After World War II parachute cord became available to civilians, first as military surplus and then as a common retail product. While some commercially available paracord is made to specification, even when labeled as such a given product may not correspond exactly to a specific military type and can be of differing construction, quality, color, or strength. Particularly poor quality examples may have significantly fewer strands in the sheath or core, cores constructed of bulk fiber rather than individual yarns, or include materials other than nylon.
Paracord has also been used by many since the 1970s for whipmaking. The durability & versatility of this material has proved beneficial for performing whip crackers & enthusiasts. Since nylon doesn't rot or mildew, it has become known as an all-weather material for whipmaking. Nylon whips have grown in popularity over the last few decades, more so in the last several years.
