Double grinner or uni knot

Use: Joining two lengths of leader material

Description: This is an excellent knot for joining two lengths of nylon because the two halves of the knot are tightened independently.

Tying:

1. Overlap the two lines to be joined by 150mm.

2. Take one end and form a loop that over-lies both lines. Pass the end around the two lines six times. Pull the end tight and form the first knot.

3. Now repeat the process using the end of the other line.

4. Pull both lines to slide the two knots together and trim the tag ends.

The uni knot and grinner knot are different the knot shown in the illustration is a double uni knot.
Saying that the uni knot is a very useful and strong knot and good for tying a dropper from.
