Uses
Easily formed in most line, the offset water knot can be difficult or impossible to untie once tightened, if the knot's dressing has parts falling out of a neat, parallel ("twin") orientation. Long used by weavers to join the ends of yarn, the offset water knot is very old. It was one of the knots likely identified among the possessions of Ötzi the Iceman, who dates from 3300 BC. The knot is also tied in a slipped form by mechanical balers to bind straw and hay, but this bend is not practical to use as a binding knot when tied by hand.
