How to Tie Single and Back-to-Back Duncan Loops (Uni-Knots)

Producer: Salt Strong

The Duncan Loop, which was authored by Norman Duncan but which is often called the Uni-Knot, is a great all-purpose knot that serves a variety of purposes, including tying tippet to fly, braid to mono, and connecting two pieces of  material with back-to-back knots.

The knot is commonly referred to as a Uni-Knot because of its popularization by Vic Dunaway as a component of his Uni Knot System.
