Strongest Braid to Braid Fishing Knot [Modified Double Uni Knot]

It's fishing knot time again! Of all the knots for fishing, the braid to braid knot is probably the least used...

But we still must make time to ensure all connections are maximized so that we don't lose the biggest fist of the day due to a break-off.

Most of all, a braid to braid connection is used to splice two sections of braid to save money and time in re-spooling...

Specifically, it allows anglers to load their full spool with braid to maximize the amount of line in the spool for when a really big fish is on, while still be able to re-spool faster and more affordably given that the line towards the bottom of the spool that is mostly untouched can stay in the spool as backing while only changing out the top ~100 yards of line that gets weakened the most due to usage.

After testing out many knots for the braid to braid connection, I found that the modified double uni knot outperformed them all.

This knot is easy to tie, has a small profile, and it has scored that highest in terms of average breaking strength of all that I have tested.

You aren’t going to believe this but I was searching for quite some time for a knot that would not come apart when I’m joining new yarn for my socks! I knit all of my hubby’s socks and occasionally when I join two different yarns they would come apart in the washing machine. Not anymore! Thanks so much for reminding me about this knot. I was raised in a fishing family and had completely forgotten about it. Blessings! Beverly

Well done video and thanks for using hi-vis line and a dark back drop. 🙏🏻

This knot IS extremely powerful, I almost got spooled by an accidental cobia hookup while fishing for spanish here in NC and this knot handled very well. You should've seen my facial expression when I felt the knot go through my guides toward the fish but landed him after a really good fight. Was fishing with a very small penn pursuit 3000 with 20lb braid. Awesome tutorial! Keepem coming!

I was searching for a knot to add a mono leader to braid. I found several but the videos all demonstrated with heavy line. They were all very difficult when using light line. I came across the double uni which I used in fly fishing and tried that. Much easier to get a good knot and they pass through the eyelets smoothly. Tried it out on a new ultralight rig and it casts perfectly. I added a tiny drop of crazy glue to the knot per the recommendation in the video.

I needed to add some line to my dad's reels, and this was just the perfect instructional for learning how to tie this braid to braid knot. Luke you made it really easy to learn, and I appreciate that. I've added new braid to two reels in just a few minutes, and I only have one more to go. Can't believe it was that easy!

Thank you for the simple demonstration of the knot. I stripped more then half the spool to splice in hi-vis braided line and Im hoping that this knot is as strong as every one is saying. Thanks for sharing.

Absolutely Awesome! I've never thought of just simply adding fresh braid to my spool that was running low! Thanks Luke & Salt Strong

Great video, really easy to follow and I now have a reel (with a tangle in the middle of the spool) cut out and tied back together. At home strength tests seem really good!

Three hours on the bank watching other videos. Maybe luck, but your video helped me crack it. Thanks 🙏🏼😂👍

I need this knot knowledge in my fishing life.

This is my go to channel for fishing knots. Just yesterday, I had trouble with my braid line and this video saved my life. Thank you for the clear visuals and instructions. 👍

Great knot i only used to use 6 wraps but never failed me !! I alway's wet braid when tying knot's far stronger !!

[dennyballgame]

Great tutorial. I actually used this last year and this year after losing some line I had a fish run me down to this connection. I was able to bring in a 28in striper with this connection exposed at least twice. I neglected to like and subscribe last year. I won't make the same mistake twice. Thank you!!

good day sir, I'm just starting fishing, thank you for the tips, it's a big help to someone like me who is a beginner in the field of fishing

Living in southern Baja. Transplanted smallmouth fisherman searching for dorado and tuna in my retirement. Thank you

[michaelohara]

Can’t believe I actually did it!! Super strong knot! Great video! Had to watch a few times to get it right…. Two left thumbs…..

[johnyeo]

Brilliant Knot. So easy to tie and super strong!! Thanks for sharing!!

[herenow]

Great knot. Much better than the one I was using for braid to braid. You helped me out loads. Thanks for sharing.

[brodiephillips]

This is often used in the UK for attaching light braid (20-30lb) to a heavy braid leader (70lb+). It sounds weird, but a lot of anglers use it whilst beach fishing with 15ft through-action rods and it chucks the lead and bait out of sight. The anglers that use braid leaders use this knot to attach it to their mainline. Great video mate.

I make jewelry with very thin braided line and this is the only thing that has worked when I run out of thread and need a bit more for a project. Thanks!
