Anchor bend

The anchor bend is a knot for attaching a rope to a ring or similar termination. It is a 'tie once, cut free knot' as it tends to lock and be extremely difficult to untie, for this reason it is usually only tied where it will rarely be necessary to release. It is the accepted knot for attaching anchors (or more usually anchor chains) to warps. The knot is very similar to a round turn and two half hitches except that the first half hitch is passed under the turn.
