The strongest of the five most popular hook knots is the Palomar at 97 percent, with the improved clinch right behind at 90.5 percent, the uni at 86.4, the non slip mono loop at 82.6, and the plain clinch last at 65.6. I tested all five with 12 pound fluorocarbon, basing the numbers on the line's real strength of 9.54 pounds. In this How 2 Tuesday I break down which fishing knot is actually worth tying.

In this test the Palomar was the strongest at 97 percent breaking strength. I tested five of the most popular hook knots with 12 pound Daiwa J-Fluorocarbon, tying each knot three times for an average and basing the percentages on the line's true breaking strength of 9.54 pounds, not the label. The Palomar came out on top, followed by the improved clinch at 90.5 percent, the uni at 86.4 percent, the non slip mono loop at 82.6 percent, and the plain clinch in last at 65.6 percent.
Coming in fifth and weakest by far, the clinch knot at 65.6 percent. Fourth, the non slip mono loop at 82.6 percent. Third, the uni knot at 86.4 percent. Second, the improved clinch at 90.5 percent. And first, the Palomar at 97 percent. The big lesson is that one extra step, passing the tag end back through that one loop to turn a clinch into an improved clinch, jumps the knot from 65.6 to 90.5 percent, a remarkable difference for one small move.
The improved clinch is exactly the same knot as the five turn clinch with one extra step: after passing the tag through the loop above the hook, you pass it back through the other loop you created, then pull tight on the standing line. That single extra pass took the knot from 65.6 percent up to 90.5 percent in my test. It is the clearest example in the whole episode that small details in how you finish a knot make a huge difference in strength.
You have to put it on a scale, because YouTube videos full of claims that a knot is strong tell you nothing without a number. Before testing the knots, I tested the line itself by tying a Bimini and breaking the spool, which broke consistently at 9.54 pounds. All my percentages are based on that real line strength, not the label on the spool. Then I tied each of the five knots three times and broke them for an average, so the results reflect repeatable performance.
Most fish are lost because of bad knots, and most knots fail because people do not tighten them down properly. A knot will slip before it breaks every time, so the fix is to lubricate the knot with spit or ChapStick, take a good turn with your hand, and pull it down really tight with pliers while you are still in the boat. Getting the knot as tight as you can before you ever cast is what gives you your strongest connection.
I tested the five turn clinch, the five turn improved clinch, the Palomar, the uni, and the non slip mono loop. I chose them because they are five of the most popular fishing knots there are, and they are often the first knots you learn, the ones that stick with you through your whole fishing career. They each get tied for different reasons, but people always ask which is strongest, so I put them head to head on the machine to find out.
I chose these five because they are the most popular hook knots there are, and usually the first ones you learn, the ones that stay with you your whole career. People always ask which is strongest, so instead of guessing I put them head to head on the machine. I explain my reasoning in the episode, so press play in the player above.
Here is the process I follow to get honest numbers and stronger knots. I cover the details in the episode.
I unpack each step in the episode. Press play in the player above.
The improved clinch is just the regular clinch with one extra pass of the tag end back through the second loop, and that single move took the knot from 65.6 percent up to 90.5 percent. It is the clearest proof that how you finish a knot matters as much as which knot you pick. I show the difference in the episode, so press play in the player above.
Most fish are lost to bad knots, and most knots fail because they were not tightened properly. Since a knot slips before it breaks, I lubricate with spit or ChapStick and pull everything down hard with pliers in the boat. I walk through exactly how I cinch each knot in the episode, so press play in the player above.
The results were clear: the Palomar at 97 percent is hard to beat, and a properly tied improved clinch is right there with it.
Whatever you tie, test your line, lubricate the knot, and cinch it down hard before you ever make a cast. Press play in the player above.

Tom Rowland Podcast — Episode 914: Which Fishing Knot is Worth Tying? (How 2 Tuesday, solo Tom Rowland)
In this episode: the five most popular hook knots put on the scale — the five turn clinch, improved clinch, Palomar, uni, and non slip mono loop — why "most knots fail because people do not tighten them down properly," testing a 12 pound fluorocarbon spool to a 9.54-pound baseline, and the 97% winner — 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.
Tom Rowland: 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 Rowland 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: We tested the five most popular knots to tie the hook to the line and the strongest will surprise you. The reason that I chose these five knots is because they are five of the most popular fishing knots there are. Not only are they popular, but oftentimes these are the first knots that you learn in fishing and they will stick with you through your entire career. This is how to Tuesday on the Tom Rowland Podcast brought to you by Danco.
Tom Rowland: Most fish are lost because of bad knots and most knots fail because people do not tighten them down properly. One of the things that we do is to lubricate the knot with spit or ChapStick or something. You lubricate the knot, then you take a good turn with your hand and you're going to pull these knots down really tight by using your danco pliers. It's been proven that a knot will slip before it breaks every time. So what we're looking for is to tighten that down with our hands as tight as we can possibly get it while it's still in the boat. That's gonna make for your strongest knot.
Tom Rowland: We test these knots because we want to know exactly what the breaking strength of the knot is. Because if you go on YouTube and you look around, you'll find tons and tons of YouTube videos that will say, this is a very strong knot or this is the strongest knot. But is it really? Unless you actually put it on the scale, you have no idea of what that is breaking at and what the percentage breaking strength is.
Tom Rowland: The five turn clinch, the five turn improved clinch, the Palomar, the uni and the non slip mono loop. These are all knots that I tie on a regular basis for different reasons, but a lot of people ask which is the strongest one. So today, what we did is we tested a spool of 12 pound DIY J Fluorocarbon. We tested that spool out by tying a bimini and then testing that line for its maximum breakage before we even started this and that line broke consistently at 9.54 pounds. So all the percentage breaking strength that we have is based off of the line breaking strength, not the label breaking strength on the spool. I tied each knot three times and broke them for an average.
Tom Rowland: The five turn clinch. This is one that most people learn as their first fishing knot. It's very easy. The line goes through the hook, five times around the standing line, through the hole right above the, the hook. Pull this tight with the standing line, not the tag end.
Tom Rowland: The five turn improve clinch, it's exactly the same knot as the five turn clinch with one extra step. Pass the line through the hook, five times around the standing line, goes through the loop that you've created right above the hook, and then pass it back through the other loop. One more time, pull on the standing line and pull it down tight.
Tom Rowland: The palomar, you pass a double line through the eye of the hook, tie an overhand knot, leave it loose, pass the loop over the hook and pull this down tight with both the tag end and the standing line in your hand. The uni knot, pass the line through the eye of the hook, leave yourself plenty of extra, make a loop, pass the tag end around both lines five times, pull the tag end tight, and then slide the knot down to the hook.
Tom Rowland: The non slip mono loop, we're gonna tie an overhand knot in the line before we pass it through the hook. Now pass the tag in through the hook, pass it through the overhand knot that you've made four times around and back through the overhand. Hold the tag end while you pull on the standing line to tighten.
Tom Rowland: Okay. Here are the results coming in at fifth place, the weakest knot by far in the ones that we've tied, the clinch knot comes in at 65.6. At number four, the non slip mono loop comes in at 82.6% breaking strength. Number three, the uni knot, 86.4%. Number two, the improved clinch comes in at 90.5%. So you can see that that one extra step of passing the tag end back through that one loop makes a remarkable difference in the knot strength. And number one, it'll be no surprise to many of you but a big surprise to some, the Palomar. It's a 97% knot.
Tom Rowland: With this test, will you still use the knot that you grew up using or will you switch to the Palomar, the improved clinch, or the uni?
