For about the past 30 years I have used a bucket of water, I fill it up to the exact weight of 15lb or whatever the BS is of my hooklength and when I have tied my rigs, I hold the loop with either 6" nail or a knot puller and very slowly try to lift the bucket, when its off the ground, the knot has passed.

I am not interested in messing about constantly topping up a bucket to find out what they break at, you don't need to know that, you just need to know that they will not break before what they are expected to break at. If you do have rigs that break well before you expect them to during testing, then its worth finding out at what BS they do break at as then you might discover you have bought a "Duff" spool of hooklength or its old etc, or your knots are not compatible with it etc or you can stop using that brand and make if their appears to be nothing wrong with it.

And my preffered knot is the Palomar

Looks like the Palomar is the next step…Trilene,,,😁

Thanks for all the info 👍

Check out YouTube. Plenty of the Yankee bass anglers have got videos testing the best knots for different materials.

I use Technium in 15lb for the vast majority of my fishing and I honestly couldn't give a fig whether my knots survive a pull of 15lb. They only need to survive the maximum pressure I can apply with my rods, plus a little, which is nothing near 15lbs. I use 15lb line because of the abrasion resistance it offers, not because I'll be putting 15lbs pressure on anything.
If I were snagged up, I would rather my mainline to swivel knot gave way first before my line, so as to leave a bare minimum of tackle in the water or up a tree. Incedentedly I can't remember the last time I pulled for a break.

Most mere mortals only break their mainline when snagged and pull for a break, and some even manage to break their line when casting.
When I used to do rig checks it was amazing/scary how many were unable to tie a solid reliable knot in their mainline and test it BEFORE casting out

Agree, Palomar is so strong if you get it right.
Unfortunately with thicker \ stiffer lines it can take a bit of effort to bed it down correctly.
You need the two bits of line going round the eye uniform. (side by side and not crossed over each other)
As you say, done wrong and it will break easily.

That's genius Roger. Bloody genius. Why on earth did you not release it? If you have, why have I never seen or heard of it before?

That is clever. It solves the massive problem of shock when anglers test lines/knots over a very short length (less than arms length).

In a carpworld full of bits of far east plastic all copying the hell out of each other, with so very little or no innovation whatsoever (except from a couple firms)... That is truly amazing. You need to promote that seriously. Because otherwise one of the known shiesters will have it ripped off instantly & sell a boat load.

Thank you and massively appreciate the feedback - we only ever made prototypes as it's all of our stuff it was very niche and anything decent was shipped to China for copying!

The idea was born years and years ago at one of the carp shows, I was chatting rigs with Gary Bayes on the Nash stand and he tied a rig up and pulled his knot tight with a hair band, I asked what he was doing - he looked at me and said 'I can snap 15lb line all day' this beds the knot in and tests it at a strength that is realistic! Took me years to put that into some kind of workable product.

I will try and get you one knocked up and you can keep that and when the NGT version comes out you can say yeah - but my spring is better and original ;0)

It's brilliant Roger. You should get it out there. People will buy that.
