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.

Hey Luke, have you ever tried testing a Double Uni using the same method of doing two turns around the other line instead of one as if you were reinforcing a single Uni knot when attaching it to a hook/swivel ?

Braid to braid, any knot is a fail.
Splice the two lines together at home with a medium size sewing needle. The south africans have a very good method that is as near 100% as you will get. Real 100%, not internet bragging rights 100%. Stronger than the PR or FG connection to your leader will be. The trick is to splice the one line through the other back and forth and not inside the line, and then take the tag of the line just stitched and stitch it back and forth through the other and DO NOT tie off the tags, just cut them a mm or 3 short. Do 30 stitches each side for your own peace of mind, 20 each side is more than adequate though. 20lb braid is not an issue to stitch.

Been using this knot for some time now thanks to you, Luke. Works a treat and is very easy once you know. Thanks for the contribution you’ve made to my fishing experiences!

What is the breaking strength as a percentage of line strength? Why not splice the lines together using splicing needles?

I assume that this knot will work on all line weights, 10lbs-10lbs, 130lbs-130lbs
