Double Fisherman's Knot

The double fisherman's knot (sometimes called a barrel knot) is used to join two Double Fishermans Knot

lengths of line. It is one of the knots most often used in climbing as well as search and rescue.

Other uses for the double fisherman's knot include:

To back up a critical knot (harness tie-in knot or single-line rappel rigs). In these instances the running end is tied around the standing end of the rope so that it cannot slip back through the knot.
The ends of a necklace cord can be tied using the double fisherman's knot and,
The Double Fisherman's Knot is the knot most employed when creating a loop for a Prusik Knot.

Basic terms used in our knot tying instructions explained here.

How To Tie A Double Fisherman's Knot

Lay two bitter ends, about 12" each, next to each other.
Wrap one end around both ropes two full turns towards the mid-point of your overlap.
Pass the end through the two turns (away from the mid-point).
To complete a Double Fisherman's Knot, do this same thing with the other end you have laid out winding in the opposite direction from your first wrap.
Snug up each knot that you have created.
When finished, pull on both ropes to slide the two knots together.

Congratulations, you have now made a Double Fisherman's Knot.

This knot can be difficult to untie once it has been put under pressure, especially if it has become wet.
