Also known as the Modified Albright Knot.
The Alberto Knot is a modified version of the Albright Knot, and is also a bend knot targeted at connecting two fishing lines of different diameters or materials. The Alberto Knot is one of the strongest knots for tying a leader to the mainline, and is also easy to tie. Just like the Albright Knot, multiple wraps are made around the mainline with the leader. However, additional wraps are made going in the opposite direction back up the line towards the mainline, which purportedly improves the holding strength of the knot.
The Alberto Knot was invented by and named after a Floridian sports angler and is closely associated with the Albright Knot. However, one common misnomer is that the the Alberto Knot is the same knot as the Improved Albright Knot, which isn’t the case as the Improved Albright Knot is actually a distinct knot that is more structurally similar to the original Albright Knot.
