How secure is a surgeons knot?
A sequence of an H2 or a 3-throw half knot (H3) followed by a H2, either symmetric or asymmetric (H2H2 or H3H2), resulted in 100% secure knots that never opened at forces below 30 N. Other safe combinations were H2H1s followed by 2 blocking half hitches, and a sequence of 5 half hitches with 3 blocking sequences.
What is the strongest fishing knot?
The Palomar Knot
The Palomar Knot is the strongest fishing knot in many situations. This knot only has 3 steps making it extremely powerful and very basic. Since there are not many twist and kinks in this knot it makes it extremely tough to break. It can be used on Braided line and Mono-filament.

The Palomar Knot is arguably the strongest all-around knot. Due to its use of a double line, it is as efficient at maintaining a high breaking strength as it is easy to tie.

Can you use a surgeons knot to attach a leader to a fly line?
The easiest and fastest knot for attaching the tippet to the leader in all kinds of conditions is the Double Surgeon’s Knot. The Double Surgeon’s Knot requires the leader and tippet to be placed side-by-side so they overlap (for about 6”) with ends facing in opposite directions.
Why do they call it a blood knot?
