The Blood Knot is a favourite knot with all fisherman. It is primarily used to join two lines of similar size, e.g., when joining sections of leader or tippet, and is one of the best knots for this purpose. The strength of the knot depends on making at least five, and up to seven, turns on each side of the center.
When lubricated and pulled tight, the knot changes its structure. Pulling on each line forces the wrapped turns to redistribute the twists so that the inner strand becomes an outer wrap.
The Blood knot is a simple, easily learned and very effective way of joining two similar sized lines.
A easy and fast way to tie the Blood Knot is with the Tie Fast Knot Tyer.

In the video below it is demonstrated how you can tie the Blood Knot with the Tie-Fast Knot Tyer

Back to Back - Use the Splice Knot to join Fluorocarbon to superbraids (fishing braid).
TOP TIP: When you tie the knots back to back lube them well with spit; and don't
pull the final tightening until both knots are done and you have eased them together.
In other words don't pull one side to final tightness and then tie the other.
If you do that then when you slide them together you will stretch the line(s) and
weaken the knot.
