I have made the long tail (tag end) red so you can follow
the next step.
Put the tag end back through the front of the loop and do
another four turns up the inside of the loop following the lay of the original
four twists.
To tighten as a loop put your fingers in the loop the
swivel is shown on, and pull the knot up slowly.
If any of the loops jump out of place give the tag end a
light pull.
Rotating the hand you are using to hold the loop open
while setting the knot will make it set much more easily.
The new uni knot can then be cats pawed to a clip or
swivel and the noose tightened. This results in a very strong join that seldom
if ever needs retying.
Sarawak Deep Ocean Anglers uses this knot extensively that
have to be both strong and hardwearing. It is also one of the better extreme
fishing knots.
Up to seven turns can be used but make sure to put the
same number of turns in both sets of twists or the knot will not pull up
correctly
