Instagram's most viral fishing knot, a lefty cray non slip mono loop tied with a doubled overhand, tested at just 74 percent breaking strength, well below the 95 to 100 percent the original delivers. With over 1.1 million plays, the video never proves the claim, so I tied it with 15 pound fluoro and broke it on the machine at 11.11 pounds. In this How 2 Tuesday I test the viral knot and show why the popular tweak actually costs you strength.

Not as strong as advertised. This viral knot from the account underscore c t r fishing, with over 1.1 million plays, is essentially a lefty cray non slip mono loop with a double overhand instead of a single overhand to start. I tied it with 15 pound Daiwa J-Fluoro and it broke at 11.11 pounds, which is 74 percent breaking strength. For a loop knot that should test in the 95 to 100 percent range, 74 percent is a real disappointment, so I gave it a big F.
It is essentially a lefty cray non slip mono loop, one of my favorite knots for bonefish flies and any light leader loop connection. The only change in the viral version is starting with a double overhand, or passing through the overhand twice, which makes a figure eight if you pull it tight. That is the whole twist on the original, and it is the part that I tested to see whether the extra turn actually helped.
No, it makes it weaker. The original lefty cray non slip mono loop is known to be a 95 to 100 percent knot, but adding that extra turn in the overhand dropped this version to 74 percent. So putting the extra wrap in the overhand is not giving the knot more strength, it is actually taking strength away. Those were my findings on the machine, and they are the opposite of what the viral video implies.
Because the common thread with these viral knot videos is that they show you how to tie the knot and then just say something like it is a very strong knot, with no proof. The only way you will really know is to tie it and test it on a machine. Control the controllable. That is how you become a better angler, and it is exactly why I take these popular Instagram knots back to the tying bench and put a real number on them.
I tied the viral knot with 15 pound Daiwa J-Fluoro and tested it on the machine, where it broke at 11.11 pounds, which works out to 74 percent of the line's strength. Putting a real number on it is the whole point, because a video that just claims a knot is strong tells you nothing. Tie it, test it, and let the scale settle the argument instead of the caption.
I would stick with the original lefty cray non slip mono loop, which is a proven 95 to 100 percent knot for bonefish flies and light leader loops. The viral version with the extra overhand turn only tested at 74 percent, so the modification that made it popular actually costs you strength. If a million people are about to tie it this way, my advice is to go back to the original and keep the strength.

Tom Rowland Podcast — Episode 916: Tom Rowland (solo, How 2 Tuesday)
In this episode: testing Instagram's most viral fishing knot on the machine, a doubled-overhand take on the lefty cray non slip mono loop with over 1.1 million plays, a break test at 11.11 pounds on 15 pound fluoro, and why the extra turn actually takes strength away — in the exact words spoken.
Tom Rowland: If you want everything you need to take care of your boat, StarBright's got the solution. It's called boat care in a bucket. That's right. One three and a half gallon bucket packed with essentials, vinyl bright, deck cleaner, marine polish, a wash mitt, hull cleaner, and boat wash. That one kit will keep any boat clean and protected, but that's just the start. I also use StarBright's salt off, which is incredible for rinsing salt off after a day on the water. Their brushes and cleaning products work just as well on your RV and patio furniture and anything else that lives outside. It is a company that gives back. That's one of the things that I really like about StarBright. StarBright supports marine conservation through Project Sea Safe, and that means a lot to me personally. You're getting performance and purpose. Visit starbrite.com. That's starbrite.com, and get your boat dialed in for the season. From The Seychelles to The Keys, I trust Nikon binoculars to find fish fast. Visit nikonusa.com and upgrade your line of sight. I thought I was covered, but I wasn't. HH Insurance showed me that my old policy did not cover The Bahamas or nighttime navigation, two major gaps that could have cost me a lot. Jake and Landon fixed it fast. They know charter policies better than anyone I've ever worked with. Call (727) 498-5551 or visit hhinsgroup.com and tell them Tom Roland sent you. Trusted enough to go with me to The Seychelles, my Danco pliers are a staple in my kit. Check out dancopliers.com and build yours today.
Tom Rowland: Hey, everybody. Welcome to How To Tuesday brought to you by Danco Pliers. We are back at the tying bench going through Instagram videos, looking at these knot videos that are incredibly popular, and then putting them to the test. Because the only way that you can really know is to actually tie them and test them on a machine. Most of the knots, the common thread with the Instagram videos is that they show you how to tie the knot, but then they say something like it's a very strong knot. How will you really know? The only way you'll really know is to test it. Control the controllable. That's the way you become a better angler, and that's what we're doing today.
Tom Rowland: This knot is from one called underscore c t r fishing. This one has 1,173,221 plays, and it is essentially a lefty cray non slip mono loop. But instead of just doing a single overhand, you do a double overhand to start or you go through the overhand twice, which will make a figure eight if you pull it tight, or you can just do it like this.
Tom Rowland: We tied this knot, and it came out at 74%. So we tied it with 15 pound diawa j fluoro, tied the knot, tested it on the machine, and it broke at 11.11 pounds, which is 74%.
Tom Rowland: So I'm giving this knot a big f because the lefty cray non slip mono loop is one of my favorite knots for bonefish flies and any other light leader type loop knot, and it is known to be a 95 to 100% knot. So putting the extra turn in the overhand knot is not giving this knot more strength. It's actually taking strength away. Those are my findings.
Tom Rowland: Will you use this knot? Are you one of the 1,000,000 people that have seen this and will now tie this knot this way? Are you sticking to the original lefty cray non slip mono loop? Tell me in the comments.
