The Albright is built for connections where the two lines are very different, a light main line or leader tied to a much heavier shock leader, or to wire. It wraps the lighter line neatly around a loop of the heavier material, giving a reasonably slim, smooth join that handles the size mismatch other knots choke on.
When and why to use it
Use the Albright to tie a lighter line to a heavy mono or fluorocarbon shock leader, or to connect line to a wire leader for toothy fish like bluefish, wahoo and sharks. It is a classic offshore and toothy-critter knot. For joining braid to a heavy fluoro leader specifically, many anglers now prefer the slim beauty for its thinner profile.
How it works
You form a loop in the heavier line or wire, pass the lighter line through it, then wrap the lighter line back over itself and the loop a number of times before feeding it back out through the loop the way it came in. Lubricate, seat the wraps carefully, and trim, keeping the coils tidy is the key to strength.
Tip Keep the wraps snug and touching, and slide them toward the closed end of the loop as you tighten. A neat, tight barrel of wraps is what makes the Albright hold; loose, crossed wraps are where it fails.
