ABOK #1439
Ashley describes it as “the bend commonly tied in hawsers and cables.” It is also makes the center of the very decorative Lanyard Knot. The Carrick Bend curls up under strain and the attractive, mat-like appearance vanishes. It is important that the tails lie diagonally opposite each other; if tied incorrectly, an intermittent pull will gradually work the knot towards the tails until it is undone!
See AnimatedKnots for instructions on making a net of Carrick Bends.
