Buffer Loop

The Buffer Loop is used to attach a lure to a line or a leader via a non slip loop.

To Tie a Buffer Loop:

Tie a simple Overhand Knot in line, leaving the loop loose and leaving the end long enough to complete the knot, and then run the end through the eye of a lure.
Run the end back through the loose loop, and make another overhand knot, using the end and the standing part of the line.
Tighten the overhand knot nearest to the lure eye, and then tighten the second overhand knot, which, if effect, forms a half hitch against the first knot.
The finished knot.
