Excellent, thanks Dominick, we are delighted the video was useful to you. Good luck in this wonderful sport of fly fishing!

Thanks Colin, glad it helps...

Glad it was helpful!

Thanks James...

You bet!

Thanks Larry. I hope you have fun in this wonderful sport...

Those are great knots. So glad you see the advantages of them, and hope you get them dialed in quickly.

@@RIOPRODUCTS Yeah I'm here practicing away the improved blood knot, perfection loop knot and the turle knot. The trilene knot is easy but this is my repertoire of new knots. Is there any advantage to using the no slip loop knot over the perfection loop knot? I like the higher knot strength of the perfection loop. Love these videos especially since you don't just show how to tie the knot, you show when they break. It's perfect! I'm planning on moving to Idaho so I'll absolutely swing by when I do that!

Sounds like you have them on a great path! We'll make sure to do better on future videos at remembering that...

Thanks Justin. Good luck with those knots!

Sadly we can't test knots any more, which is a shame as we have stockpiled a few we would like to run similar tests on!

Absolutely! We already did that as we were curious too. You can watch it here: kzfaq.info/get/bejne/rJt8lqVels3OqqM.html

Thank you!

We were surprised at that too. Remember it was only a one knot test, so it could have been tied incorrectly. We just didn't have time to do multiple tests on all the knots. Everyone at RIO still firmly believes the Improved is stronger. We'll have to run those tests again to check.

@@RIOPRODUCTS thanks. A few knot tests would be useful.

Thank you John, glad you are enjoying the knot series! Should we add a Part Two, we will certainly consider adding the Swirl knot into the mix. Cheers!

It might, a tiny fraction, but even the tightest clinch knot, still swivels around the eye when playing a fish, and because it is tighter than the non slip loop knot, might actually have more friction. Not sure how to test that!

We'll have to look into that one!

Lol.... ahhh.....you just did...... in this video posting.........

Yes, this would be a very good knot for tying a hook on for sea bream fishing...

The problem with that thought is that when you pull the tag end, you loosen the trule know, so if you caught a fish on the fly on the tag end, you'd loosen the other knot...

That's a good point. As long as the two ends are kept tight and opposing each other, it can't slip undone!

Its 92%of its actual breaking point, 10lb is the rated strength which is a tag shy of its actual tensile strength

A good rule of thumb is that the maximum length of tippet that will turnover is the same number of feet as the pound breaking strength. In other words, if you have 4lb tippet, you could turnover up to about 4 feet of it - on the end of a tapered leader. If your leader is not tapered, it will be greatly reduced. Generally, I like 6-8 lb tippet for buzzer fishing, and 8-10 lb for pulling...

RIO Products Thank you for taking the time to reply, really appreciate the advice and look forward to more of your videos.

Sorry, Zack can't recall as it was along time ago. We think it is about a 6/0, though...

It is the strongest of all loop knots for sure - as strong as the material itself.

Hi Carl, we used the same spool of 10lb steelhead/salmon tippet for every knot we tested in this film. In many of the tests the line did break, but at the knot where the knot had cut into the main material and weakened it slightly. This is usually the cause of so called knot "failure". Thanks for watching, and for commenting...

I watched again very closely - you can clearly see in the Homer Rhodes and Trilene knots that the line broke 1 to 1 1/2 inches away from hook eye. The Improved Clinch knot looked like the hook either broke or pulled free from the testing machine. I'm also puzzled by your percentages - you said all were tied in 10 lb test line, so why is the Trilene knot rated at 99% when the line broke at 10.4+ lbs, which should be 104% of the test strength rating? For my money, the Trilene knot is the clear winner, having not failed even when the line test was exceeded.

Hi Carl, thanks for getting back on this. I am guessing the honer rhodes and trilene knots broke where tippet had been crushed by the knot as it was tightening. That would be the only explanation of why it broke short of the knot. As to why the Trilene wasn't shown above 100% in strength, the reason is that the 10lb tippet actually broke at something like 10.6lbs, not 10lbs, and so the knot percentage was based on the actual material strength - not what the label said. I agree, the Trilene knot is the clear winner!

+Robert Fernandez something the size you'd need to catch a tuna

It varies with all the knots, but between sz 12 and 8 is used

The main two knots you use on flies should be the clinch/improved clinch and the non slip loop knot. The reason is as you suspected, to keep the fly fishing straight from the hook with the loop for better fly movement. Almost all saltwater and steelhead anglers use the loop knot for their flies, and trout anglers for streamers. For dries, nymphs and soft hackles the clinch is totally fine.

Agreed. There is 5" of leader if you slow it down. The Trilene held 100%, or more, of the original strength.

The sample of steelhead tippet material we used actually broke at 10.6lbs, not 10lbs, so we used this as the base number.

Thanks for the clarification!

Totally!! We should have made that clearer... Thanks for the feedback.

Understandable, just super hard to translate on camera!

Guess that's another one to add to the list!

The Turle and the non slip loop are the most consistent...

Quite a bit more reliable - especially in thinner line..

Gaming Glow Same here. I went to the improved clinch but last season went with the Davy knot. Smaller profile, easy to tie and very strong

Clinch Knots will definitely slip. The Davy Knot is a cool, simple little knot, but also has a reputation for slipping some. I think the Turle Knot is a nice knot and has a tendency to come straight out of the eye of the hook. It's a bit more difficult to tie than the Improved Clinch in my opinion, but to each their own. Improved Clinch Knots are easy to tie, do not slip and are very strong. It's my favorite for trout fishing for tippet to fly. The Non-Slip Loop Knot is a great knot, but a little more complicated. Great knot though.

In America, the Blood Knot, is a different knot than the Clinch Knots. I believe that was the same in England as well, as I have read many books from when fly fishing originated and they always indicated as such. Advantages of being an old geiser who has fly fished his whole life. LOL

@@gregory4457 You are right Greg Harris Because I'm 74 an old geezer also the things he called the clinch and improved clinch were only half tied poor examples. They were not tied in the proper way.The minimum number of wraps on any lure or fly is 5-7 and it i never used for joining lines or leaders started many years ago using the clinch and moving to the improved clinch after using granny knots as a greenhorn kid. I had no teacher. Three wraps will fail for sure and most of the time will give you curly tails which is a slip and not a break. If you notice he mentioned slipped a lot. I don't believe he got very many breaks on his test especially from just the clinch . I usually got a slip with three wraps just pulling six pound test mono while tightening up. The improved clinch is what i used almost sixty years on lures, hooks and swivels and and has never failed me on mono when properly tied. The blood knot as far as i have ever seen or read is used only in joining lines or leaders. The blond headed guy in the next video is worse than this guy.The new guys on here need to do a search on how to tie fishing knots on google and see the correct way or at least check out catfish and carp web on you-tube and his ten knots and rigging's which will serve most of your fishing needs.The Palomar knot is about the easiest and strongest for lures that I know.

@@r.w.3339 the palomar without the doubt is the best knot for lures.

Totally makes sense to run more tests than a single one for the knot average breaking strength - we know that, but didn't have time with the filming schedule we had for that video :(. We'll ask the R&D team if they can run that test again with the Trilene knot over 20 samples to get a more realistic average. Sadly they just left for a product testing trip to the Bahamas, so will be gone for 10 days, but when they get back we will see what they can do.

@@RIOPRODUCTS Product testing in the Bahamas. Sweet gig!

Any knot with double loop inside hook eye will always be better than single loop inside hook eye. It's physics, not religion believe.
