The uni-knot is as simple and versatile as knots get. Use it to tie on a hook, lure or swivel for a fast and secure connection. The uni-knot allows the angler to snug the knot to the standing part of the line, away from the eye of the hook, to form a small loop that improves the retrieve action on some lures. Set the hook after a strike and the knot tightens down to the eye of the hook without compromising line strength. After the catch is released, the angler can pull the knot away from the hook eye, moving it up the standing part of the line to recreate the loop and resume fishing with the strike-inciting action.
