This is ABOK (Ashley Book of Knots) 2206. Since it has 12 faces as compared to the 6 faces of a regular monkey fist it is sometimes called the double monkey fist. It requires a LOT of twine in the set-up, about half of which will be recovered when the knot is tightened. Here is how the lay-out looks - about 10' of paracord
Tightened around a 7/8" diameter core - about 5 1/2' of paracord left over
The fist is made up of 4 circles. You must put in the desired number of turns in each circle before going on to the next circle.
Start at the outside of each circle. I am showing only two turns in each circle to make the layout easier to see.
In this tutorial the standing end is on the right and the working end is on the left.
Circle 1 - Clockwise
Circle 2 - - sharp turn - Counterclockwise - go over, under turns of first circle
Circle 3 - clockwise - go under, over, over, under the turns of circles one and two
Circle 4 - 180 degree turn over the turns you just went under then clockwise under, over, under, over, under the turns ov the previous circles
Slack in this knot must be taken out slowly. I find that it is easier to hold the working end and gradually take out the slack towards the standing end. In this way the circles are closing in on themselves from inside to outside.
