technology Maturity 11-13 Next article →

The figure-eight knot is a very useful tool. It is a type of stopper knot. A stopper knot keeps a rope from sliding out of a device. People use it for sailing, rock climbing, and caving. This knot is special because it is easy to handle. Some knots, like the overhand knot, jam very tight under strain. You might even have to cut the rope to fix an overhand knot. The figure-eight knot also jams when pulled. However, it is usually easier to undo than the overhand knot.

There are many ways to tie this knot. One way is the figure-eight loop. This loop helps climbers move up or down a rope. It works with a harness and a locking carabiner. Another way is the figure-eight bend. This is used to splice two ropes together. You can join ropes of different sizes this way. You start by tying a loose knot in the larger rope. Then you thread the second rope through it. The two knots sit partly inside each other. They tighten their hold when you pull them in opposite directions.
