A zeppelin eye knot, is a secure, jam resistant fixed size loop knot based on the zeppelin bend.

It is one of the few eye knots suitable for bungee.

For example, the Sheet bend (ABoK #1431) has a corresponding eye knot which is none other than the common (#1010) Bowline.

The Zeppelin bend is formed from 2 superposed loops of opposite chirality.

There are two versions of the zeppelin eye knot depending on how it is tied.
