It’s knot time again!
And this time we’re covering a new type of connection… we’ll be tying a braided line to another braided line.
After getting a lot of great feedback from the braid to fluorocarbon leader knot contest, I started getting a good amount of questions from anglers wondering how to best connect two braided lines together.
Why Tie A Braid To Another Braid?
The most common use for a braid to braid knot is to splice a braid backing to the top ~100+ yards of braid in order to save money and time when re-spooling (allows for the untouched backing to stay on the spool while applying a fresh top section).
Given the multiple requests for this knot, I decided to do some testing and found that the knot shown below generates the highest breaking strength.
How To Tie A Braid To Braid Fishing Knot
After testing some of the most popular knots (blood, traditional double uni, albright, alberto) to connect a braided line to another braided line, I found that the Modified Double Uni Knot shown in the video below has the highest breaking strength.
This knot is easy to tie, it is very small once complete, and it’s hold strength has been testing just as strong as connecting to a swivel or a leader, so there isn’t much (if any) loss of strength to the overall system due to the splicing of the braid.
Here is a video showing exactly how to tie this impressive knot:
Note: This knot is the popular Double Uni Knot for line to line connections with just a slight adjustment in doing 10 wraps on each side vs. the traditional 5 wraps.
Conclusion
Our knots are always the weakest points of the line system, so it’s on us to ensure we’re using the strongest options for all types of connections so that the biggest fish of the day doesn’t get away.
And when in need of connecting a braided line to another braid, then this Modified Double Unit Knot for Braid is a fantastic option.
It’s easy to tie, has a thin profile, and it’s breaking strength has been the best I’ve tested for this connection so far.
If you have any braid to braid knots that you’d like me to test it against, please do not hesitate to let me know using the comment section below.
Tight lines and strong knots!

thanks was all i kneed to know very helpful
New to saltwatr fishing…I got pretty messed up in Iraq from IED…really hard for me to tie knots cuz hand shakes from nerve injury…it easier for me to use a swivel instead of of uni knot…
can I still use a swivel? I Have a tool that helps me with tie knots
Yes, you can still use a swivel. Just try to go with the smallest one that you feel comfortable using.
Hi Leonard ,
Sorry to hear about your injury, you can use two or more “plunger style hackle pliers” instead of your fingers for pinching the line.
You can put each of these on a retractor and attach it to your chest pack/t-shirt etc.
You can also attach a magnet near the retractor to prevent the tools swinging around.
5 wraps don’t slip and make a smaller knot. I leave one inch tags for slip safety anyway. I fish 80 lb test braid for deep line. Double uni is stronger than blood knot by quite a lot, I used to use blood knots but had too many failures.
The needed wrap count varies by line diameter… an 80 lb line doesn’t need as many wraps compared to the 20 to 30 lb lines that I’ve been focusing these tests on.
I’m curious to know more about your testing of the Uni vs. the Blood knot because my tests with lighter lines resulted in the blood knot winning in terms of strength. When you compared the Uni to the Blood knot, did you use the same amount of wraps for each? If yes, how many did you use?
Hey Luke, I must be reading something incorrectly, In your reply you mention that with lighter lines the blood knot wins in terms of strength. If so why are you recommending the modified uni knot?
Also, just wondering if you have tested/tried a sort of modified fg – in other words adding more wraps, as you have with the uni? I understand, as you have said, the braid needs to dig in, so extra wraps may not be helpful, but just wondered if you have tested it. The reason I ask is that your video on how to tie the fg knot was the first one that was very helpful and now I have gotten pretty proficient in tying it. And would like to keep using it to splice braid to braid, if it would work.
Thanks for all the helpful videos. Have really enjoyed the knot tying tests and have made changes because of the videos.
It is very tough to tie a blood knot with 2 braid lines out in the elements (this modified double uni is much easier).
As for the FG knot, I do not trust it with braid to braid because I have never found a way to prevent if from slipping before it gets even close to its breaking point.
Makes great sense. Thanks
I have a 10” rod with a reel rated for 575 yards if braid but the shop misread it and spooled it with 300 yards only. I just fish from ocean docks and bridges. Is 300 yds too short to where I could end up hooking a fish that I need to allow to drag line and not have enough? Should I get an extra 300 yds spliced onto the first 300 yds?
It depends on what you’re targeting and how much distance you need for casting… 300 yards is more than enough to handle anything under 100 lbs. So I’d be mostly concerned with the negative impact of casting performance from having too wide of a gap between the lip of the reel’s spool and the line. For that factor, I’d load the extra 200 yards of line on top of what’s there by tying the knot shown above.
Just came back to this one. A great post as I think many can benefit from backing their braid.
I previously had been using Albrights, but have re-tied them all.
I started backing all my reels so that I only need to change the top 150 yards on both my inshore spinning reels and my offshore jigging reels. Now every year I can buy one spool (300 yards) for each reel size and re-fill both reels in each class with half of the 300 yard spool if needed.
Its also great if you have a disaster while out on the boat and have to make an emergency line change.
For my offshore reels, I started using an old star drag reel to reel the line off of the factory line spool and then put that in a vice and then wind on the braid back off of that reel under about half of my max drag setting so it goes on nice and compact. I can’t put the drag on the factory line spools without it digging in.
Thanks for posting the helpful info Ryan!
I’ve used this knot 100s of times and it always holds up- thanks for sharing with everyone so they can use it.
Awesome thanku much
I have tried this 100 times. Every time it has snapped the line after checking when I pull the braided lines away from each other to check the knot. WTF?!
What lines are you using? Any idea how much tension you’re putting on it when it breaks?
Have you tried an fg knot for braid to braid it seems to work I use about 30 wraps,it makes a small knot and it doesn’t hang up on the line spooling of the reel maybe you could test it
Yes, I tried it on braid to braid and it did not perform well. The problem is that the braid can’t dig into itself like it does with mono/fluoro, so it’ll eventually slide off when enough tension is applied.
To test it out, just pull on the line until it either breaks or slides off… it has slid off every time I’ve tried it.
Let me know if you find that it holds.
Your not doing it right. The tighter you pull, the tighter the knot gets. I just did braid to braid test and literally could not pull it apart or break the line with all my might.
What would happen if you did the same process with two line thicknesses instead of one?
This braid to braid knot works well for line of different diameters too.
