Braid To Fluroucarbon Tiny Knot, Double Albright Knot,

The late, great fishing guide and angler Jimmy Albright devised this knot. But here a slightly improvised version can be used to connect greatly varying line tests, as well as slick braided line to leader material, including fluorocarbon. The Double Albright also can be made with fly lines, and even single strand wire. Plus its easy to tie.
