Zeppelin bend


From Zeppelin bend:

A Zeppelin bend is a symmetrical and inherently secure end-to-end joining knot. It is remarkable because it is stable and secure and totally resistant to jamming. It is resistant to the effects of slack shaking and cyclic loading. There is no load test that has managed to induce jamming. The structure fundamentally consists of two interlinked overhand knots (#515). The Zeppelin bend has point inversion symmetry.
