When a stopper knot is tied outside another knot and around the standing part it can also be called a '''backup knot'''. | When a stopper knot is tied outside another knot and around the standing part it can also be called a '''backup knot'''. Tying the end around the standing part helps prevent the knot from unraveling by not allowing the end to slide back into the knot. Examples of this usage are often seen in [[climbing]], [[rope rescue]], and other safety-of-life situations. The most common knots used for this purpose are: | ||

For example if a [[Sheet (sailing)|sheet]] becomes jammed on a [[winch]] while under sail, a "stopper" can be used to temporarily take the strain off the winch while the riding turn is cleared.
