The figure-eight knot is a type of knot. It is very important in both sailing and rock climbing as a method of stopping ropes from running out of retaining devices. Unlike the overhand knot, which will bind iron-hard under strain, often requiring the rope to be cut, the figure of eight can be easily untied after even the greatest strain. Different types of figure-eight knots:
- Double figure-eight knot (figure-eight loop): used like an overhand loop knot. This type of knot can be used in prusik climbing when used in conjunction with a Swiss seat, a climbing rope, and locking carabiner designed for climbing, to ascend or descend with minimal equipment and effort.
- Figure-eight splice knot: used to quickly and effectively splice together two ropes, not necessarily of equal diameter. This knot is tied starting with a loose figure eight knot on one rope (the larger-diameter one if unequal), and threading of the other rope's running end through the first figure eight, starting at the first figure-eight's running end and paralleling the path of the first rope through the figure eight until the second's ropes running end lies parallel against first's standing end. The result is two figure-eight knots, each partly inside the other and tightening its hold on the other when they are pulled in opposite directions. This can be a permanent or temporary splice. While it precludes the ropes' slipping relative to each other, it is a typical knot in having less strength than the straight ropes. A blood knot is a better[citation needed] knot for rope splicing, but is more difficult to achieve[citation needed].
How to Tie
- Make a bight in a rope
- Loop the other side through the bight
- Loop the loop x2
- Pull
