Application: The Duncan Loop, sometimes called the Uni Knot can be used for tying a fly to a leader/tippet and for tying a section of tippet to the hook shank for multiple fly nymph rig. It is also useful for any fishing application that needs a knot that is adjustable.
Tip: With any knot, it’s always best to lubricate the knot/loop with saliva or water, then pull tight, and trim close. Tightening a knot without moisture can cause the monofilament to burn making the knot weaker.
*Weak Knots=Lost Fish.
Step 1: Make a loop with the line leaving approximately 4 inches.
Step 2: While holding the loop make a bend in the running end of the line and hold them both together.
Step 3: Take the tag end of the line and wrap the line around the running line and through the loop 3 to 4 times. *This knot/loop will slide along the running end of the line allowing you to cinch or loosen the loop as needed.*
Step 4: Lubricate the knot/loop with saliva or water, pull tight, and trim close.
