  2. Figure-eight knot - Wikipedia

    en.wikipedia.org/wiki/Figure-eight_knot

    The figure-eight knot or figure-of-eight knot is a type of stopper knot. It is very important in both sailing and rock climbing as a method of stopping ropes from running out of retaining devices. Like the overhand knot , which will jam under strain, often requiring the rope to be cut, the figure-eight will also jam, but is usually more easily ...

    Figure-eight knot of practical knot-tying, with ends joined. In knot theory, a figure-eight knot (also called Listing's knot [1]) is the unique knot with a crossing number of four. This makes it the knot with the third-smallest possible crossing number, after the unknot and the trefoil knot. The figure-eight knot is a prime knot.

  4. Figure-eight loop - Wikipedia

    en.wikipedia.org/wiki/Figure-eight_loop

    A figure-of-eight loop tied using the follow-through method. A figure-eight loop is created by doubling the rope into a bight, then tying the standard figure-eight knot.. In climbing, this knot is used to save time when repeatedly attaching the rope to climbing harnesses, using locking carabiners, such as when a group of people are climbing on the same top-rope.

Can be tied by taking a bight of rope and tying a figure-of-eight knot, or can be tied directly around/through objects by weaving back through the first figure eight knot ( Figure-of-eight follow through ), which is the standard method for attaching a rope to a ...

    en.wikipedia.org/wiki/Double_figure-eight_loop

    A double figure-eight loop, (also known as a bunny ears, or a dog eared loop) is a type of knot that forms two parallel loops, and resembles the figure-eight loop. [1]It is frequently used in climbing and caving as an easily untie-able knot that is capable of being attached to two bolts and equalised.
