Fernand Petzl, born in 1912, began his caving career in the late 1920s and early 1930s. In 1936, Petzl was introduced to, then small-time caver, Pierre Chevalier. The two began work on improving the technology behind their sport. In 1943, Chevalier designed and tested the first nylon rope to replace caving ladders. This technology provided the ...
Certain specialty forms of ascender - but not all - are capable of taking a dynamic load (as in preventing a fall), whereas the friction knot/Prusik combination may abrade the synthetic sheath of the climbing rope or sling and fuse under such extreme forces. [10]
Some climbers will use a single full-thickness climbing rope with a diameter of approximately 9 to 11 mm (0.35 to 0.43 in), and some will use double ropes, or "half-ropes", to reduce rope drag (e.g. one rope is clipped into any given anchor or protection point), which have a reduced thickness of approximately 8 to 9 mm (0.31 to 0.35 in) to ...
