Episode Show Notes

The uni knot and the San Diego Jam are both excellent terminal knots, and in my test they were nearly dead even: tied in 20-pound Daiwa J Braid fluorocarbon off the same spool, the San Diego Jam broke at 20.08 pounds and the uni knot just edged it out at 20.24 pounds. In this How 2 Tuesday I put two of the most popular hook-and-lure knots head to head in an East Coast versus West Coast battle to find out which is actually stronger.

Frequently Asked Questions

Is the uni knot stronger than the San Diego Jam?

Just barely. I tied the uni knot with five turns and the San Diego Jam with seven turns, both in 20-pound Daiwa J Braid fluorocarbon off the same spool. The San Diego Jam broke at 20.08 pounds and the uni knot broke at 20.24 pounds. The uni edges it out, but the gap is so small it comes down to personal preference.

What is the difference between the uni knot and the San Diego Jam?

Both are terminal knots for tying on a hook or lure, and both are extremely popular. I think of it as an East Coast versus West Coast battle. The uni knot I tied uses five wraps and the San Diego Jam uses seven. They are built differently but in my test they delivered almost identical strength.

How many turns should you use on a uni knot?

For this test I tied the uni knot with five turns, which is a common count for a terminal connection on the hook or lure. Five wraps gave me 20.24 pounds on 20-pound line. The uni is versatile and you can adjust the turns, but five worked great here.

How many turns should you use on a San Diego Jam knot?

I tied the San Diego Jam with seven turns for this test, and it broke at 20.08 pounds on 20-pound line. Seven wraps is a standard count for the San Diego Jam, which is a favorite of a lot of West Coast anglers throwing iron and live bait.

Which knot should I use, the uni or the San Diego Jam?

Honestly, you cannot go wrong with either one. Both broke right around the full rated strength of 20-pound line, 20.08 versus 20.24, so it really is a matter of personal preference. Tie the one you can tie cleanly and confidently every time and you are in great shape.

What line did you use to test these knots?

I used Daiwa J Braid fluorocarbon in 20-pound test, pulling line off exactly the same spool for both knots so the comparison was uniform. Testing both knots on identical line is the only way to know the difference you are seeing is the knot and not the line.

Why I Tested the Uni Knot Against the San Diego Jam

I know a lot of anglers who only tie the San Diego Jam and just as many who only tie the uni knot, and both swear theirs is stronger. Rather than argue about it, I tied the uni with five turns and the San Diego Jam with seven and broke them both. I break down what I found in the episode, so press play in the player above.

How to Tie and Test the Uni Knot and San Diego Jam

Here are the steps I walk through in this How 2 Tuesday, with the full demonstration in the episode.

  1. Pick your two knots. Choose the uni knot tied to the hook or lure and the San Diego Jam as the head-to-head competitor.
  2. Tie the uni knot with five turns. Run the line through the eye, form a loop, and make five wraps through the loop before snugging it down.
  3. Tie the San Diego Jam with seven turns. Build the San Diego Jam with seven wraps so each knot is at its standard turn count.
  4. Use identical line for both. Pull 20-pound Daiwa J Braid fluorocarbon off the same spool for each knot so the test is uniform.
  5. Lubricate, cinch, and test. Wet each knot, cinch it down smoothly, and pull it to failure to compare breaking strength.

I unpack each of these in the episode. Press play in the player above.

How Close Was This Knot Battle?

The San Diego Jam came in at 20.08 pounds and the uni knot at 20.24 pounds. Both knots essentially held the full rated strength of 20-pound line, so the difference is razor thin. I explain why that means you really cannot lose here in the episode, so press play in the player above.

Final Thoughts From Me

When two knots break this close together, the decision comes down to which one you can tie cleanly and confidently every single time. Both of these are strong, proven connections.

We have now tied and tested over 40 knots on the podcast, and they are all in the free knot guide with the numbers side by side. Tie the one you trust and go fishing. Press play in the player above.

Tom Rowland Podcast — Episode 892: The Uni Knot vs. The San Diego Jam (Solo — How 2 Tuesday)

In this episode: the uni knot versus the San Diego jam, an East Coast versus West Coast battle, five turns against seven on 20-pound Daiwa J Braid fluorocarbon, the breaking-strength results, and the free knot guide with over 40 knots tested — in the exact words spoken.

00:00 · Cold Open

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.

00:52 · Nikon Binoculars, From the Seychelles to the Keys

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.

01:00 · The Insurance Gaps I Didn’t Know I Had

Tom Rowland: 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.

01:27 · Danco Pliers and an East Coast vs. West Coast Battle

Tom Rowland: 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. Is the uni knot stronger than the San Diego Jam? It's a West Coast versus East Coast battle. Stay tuned for the results at the end.

01:44 · How 2 Tuesday: Two Very Popular Knots

Tom Rowland: What's going on, everybody? It's how to Tuesday on the Tom Rowland podcast brought to you by Danco. Today, we're tying and testing two very popular knots. We have the uni knot, which is used for a number of purposes. The one we're tying today is used to tie on the hook or lure.

02:02 · The San Diego Jam Steps Into the Ring

Tom Rowland: We're gonna test that against the San Diego jam knot. These knots are both very, very popular. I know many people that only tie the San Diego jam, many people that only tie the uni knot. We're gonna find out today which is actually stronger.

02:17 · The Test Setup: Five Turns vs. Seven on 20-Pound Fluorocarbon

Tom Rowland: So today, we're tying the uni knot with five turns. We're using Daiwa J Braid fluorocarbon in 20 pound test, and we're tying the San Diego Jam with seven turns with exactly the same line coming off exactly the same spool for 20 pound test so that we have a uniform test.

02:39 · Knots Tied — Time to Break Them

Tom Rowland: So for detailed description of how to tie these knots, go to our YouTube channel and that link is in the description. So we've tied these knots. Now let's test both of them.

02:52 · The Results Are In

Tom Rowland: The results are in, and we have a winner. The San Diego jam broke at 20 o eight pounds, and that is on dial with Jabrade 20 pound fluorocarbon off the same line. The uni knot broke at 20.24, just edging out the San Diego jam.

03:10 · 20.08 vs. 20.24: Both Knots Are Very Strong

Tom Rowland: What I can say about these knots is that both of them are very strong. You're not gonna go wrong with either one. It's really simply a matter of personal preference. You got 20 o eight versus 20.24, slight edge to the uni knot.

03:25 · The Free Knot Guide: Over 40 Knots Tested
