Euro death-knot (aka EDK or European Death Knot) refers to one of a few flat bend knots used to connect two rope on rappels longer than 50 to 60 meters in length. The Overhand bend and the One-sided Figure 8 bend have both been referred to as EDK. The Overhand Bend (EDK One-sided Overhand bend is a Knot used as a simple method of joining two ropes together The Overhand Bend (EDK One-sided Overhand bend is a Knot used as a simple method of joining two ropes together
While EDKs have the advantage of pulling more cleanly after a rappel and thus may avoid binding or becoming difficult to retrieve, these knots can also invert leading to catastrophic knot failure (capsizing).

If using one of these knots, it is recommended to leave the tail longer than twelve inches (305 mm) . This is needed to allow the knot to capsize, avoiding failure. [1][2] The capsizing potential is also decreased by pulling the knot very tightly prior to use.
There are reports that the figure-eight version is less stable than the overhand, due to gentler bends creating less friction in the knot.
Warning rappelling is inherently dangerous and rope systems for rappelling should be set-up by experts.
