Åttaknut

Åttaknut, literally “eight knot” in Norwegian, is a term used in ropework to describe knot formations that resemble the numeral eight when tied. In Norwegian ropework and sailing literature, åttaknut is closely associated with the figure-eight knot, which is the standard eight-shaped stopper knot widely used by climbers, sailors, and riggers. The term can also refer more broadly to related eight-shaped knots or variations that produce a similar silhouette.

The figure-eight knot is made by forming a loop or cross over the standing part to create an eight shape, then feeding the working end back through the loop. This produces a secure stopper that is resistant to jamming under load and relatively easy to untie after tension is released. Common variants include the figure-eight on a bight, which creates a fixed loop, and the figure-eight bend, used to join two rope ends. These knots offer advantages in terms of clarity, reliability, and inspectability.

In practice, åttaknut appears in nautical instructional materials, climbing manuals, and rope-handling guides in Norway and other Norwegian-speaking communities. It is one of several eight-shaped knots used to manage rope ends, anchor points, and attachment loops. Related knots in the broader ropework tradition include the overhand knot and other stopper knots, as well as the general family of figure-eight knots.
