Figure-eight loop

This knot creates a strong loop at the end of a rope. It is used extensively in climbing, caving,

and rescue operations, because it is easy to learn and to inspect visually. The only drawback is
that it binds tightly under heavy loads and takes some effort to untie.

Start with a bight at the end of the rope to make a loop. Wrap the working end of the loop around
the standing part from front to back (1). Bring the working end back around to the front before

feeding it through the loop you have created (2). Pull the loop away from the standing line to
tighten (3). Contouring of the knot so that the lines are even and parallel will create the strongest
knot (4) and will make it easier to untie.
