Page "Kernmantle rope" Paragraph 2

The nylon ropes that were used in yachts for hauling were tested and found useful in climbing and caving, and are now the modern standard.

Although there are occasional innovations, the type of rope used today is similar in construction, strength, and durability across manufacturers.

There are several major manufacturers, including Pigeon Mountain Industries ( PMI ) which is popular with cavers, Mammut, Sterling, Beal, Edelweiss, Blue Water, Roca, Tendon and Maxim.

Overall there is a huge variety of climbing ropes available for different kinds of uses ; for instance there are well over hundred different dynamic single ropes ( the most popular rope system in climbing ).

Kernmantle ropes are still used in sailing and other sports, but the technical requirements are usually not as rigorous as in climbing since those applications are not as safety critical.

Smaller kernmantle ropes are commonly called accessory cord ; they are often used to make prusik knots and loops or attaching accessories such as chalk bags.
