Breaking strain vs knot strenght vs fish that got away

[mark]

I took advice from The largie whisperer in one of the threads and bought Maxima plus, its thinner than Rio and personally I think it's one of the best mono lines out there

So all things being equal and you tie a perfect Knot of 6x onto 5x what is the breaking strain at the knot..?

Depending on what knot you use, with a Blood knot 95% of the 6x breaking strain. That is if you tie the knot correct, without any stuttering in the closing of the knot

It's difficult to determine the strength of a knot in pounds of strain. A 6x tippet, has a breaking strain of around 3 pounds, but this is also dependent on many things, as I have taken much heavier fish on than 3 pounds on 6x. It comes down to your own fishing style, your rod's ability to protect the tippet, and the quality of the tippet. I have also lost small fish to breakoffs, on much heavier tippets, so it is very difficult to say, but I recon that a good knot should work every bit as well as the tippett itself.

What Andre has said is pretty much spot on, it comes down to shock loading. Most lines will test far higher in a gradual pull than a sharp sudden pull.

To give you an idea how different these two numbers can be, artlure and deep sea guys generally set their working drag at a max of 30% of the breaking strain of the line.

Hi Mark,

Im pretty sure I said Platinum and not Maxima.

Guys

As a matter of interest, and not quite relevant to leader/tippet knots, We had a knot competition one night at the bar in Alphonse. The guides plus whoever else wanted to enter had to tie their preferred knot to one end of a thin steel pipe. The competitor tied his knot to a similar piece of pipe. I think we used 30 lb mono as the line. The competitors held onto their pieces of pipe and pulled apart. The winner was obviously the knot that held.

At the end, a blood-knot won the day.

Interestingly, we also did an experiment where we introduced a "windknot". Not one breakage occurred at the windknot, the pipe (or hook if you like) knot always broke first.

After the competition I did and experiment by wrapping the mono around the pipe twice and simply ended it off with two half hitches. This home brewed knot beat the winning blood knot. My theory was that two wraps had a much higher friction component that did the work or resisting the load.

So, maybe we should think about passing our line through the hook eye twice before completing our knots, especially for salt water application?

There is a knot like that somewhere, not so? Quite sure about it. Thanks though Neil - will look into this!

Where does a Surgeons knot fit in to all this, breaking strain i mean.

Interesting this. Also twice through the hook eye. Similar too for the Palomar knot.
