Figure-eight knot

It is very important in both sailing and rock climbing as a method of stopping ropes from running out of retaining devices.

The name figure-of-eight knot appears in Lever's Sheet Anchor; or, a Key to Rigging (London, 1808).

The figure-eight is much easier to untie than the overhand, it does not have the same tendency to jam and so injure the fiber, and is larger, stronger, and equally secure.The stevedore knot is an extension of simple figure-eight knot with an additional turn before the end is finally tightened.

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.

The offset figure-eight bend is a poor knot that has been implicated in the deaths of several rock climbers.
