Fishing Knots and Rigging

The Modified Double Uni Knot is used for line to line connections. The most typical applications would be for tying backing to a main line or for tying the main line to a leader.

Lay ends of both lines parallel to each other, facing in opposite directions.
Loop one line over the other, creating a loop.
Wrap this line around both lines three times.
Bring the end of this line back around through the loop that was created by twisting this line around the other line.
Moisten this knot and pull tight.
Take the end of the second line and loop it around the line you’ve just finished tying, creating a loop.
Wrap this line around both lines three times.
Bring the end of this line back around through the loop.
Moisten this knot and pull tight.
Pull both pieces of line simultaneously, pulling the knots tight against each other.

Trim the tag ends.
