Tarbuck knot

British climber and skier Ken Tarbuck devised this adjustable loop knot in 1952 for use in the

new nylon climbing ropes; but it proved to be damaging to the more hi-tech kernmantel (core-
and-sheath) ropes that superseded them, so it was discarded. It remains an effective slide-and-
grip loop, however, to tighten and slacken off such diverse, general-purpose cordage

applications as tent guy-lines or clotheslines.

This knot must be wrapped and tucked just so. With the working end, take two full turns around
the standing part to form a loop (1). Bring the end up at the front of the knot (2), and pass it
around the back of the standing part, before tucking it over and then under itself (3). Methodically
tighten all parts of the knot (4). Unloaded, it can be slid along to increase or decrease the size of the
loop; loaded, it locks up.
