The Uni Knot

Of all the fishing knots out there, the Uni Knot is one that all anglers need to know because it can be effectively used for so many different connections.

Many anglers refer to the Uni Knot as “The most useful fishing knot.”

Not only can it be used for tying directly to hooks and lures (traditional “uni knot”), but it also can be used for connecting two lines together (“double uni knot”)…

And it works on an assortment of different lines and sizes.

So knowing just this one knot, an angler can be ready handle almost all knot needs that come up while fishing.

Its breaking strength has performed well in our knot strength contests while it is surprisingly basic in nature to tie.

And since it’s easy to tie, it’s a fantastic knot for teaching to kids so that they can be ready to tie complete leader assemblies while only having to remember one knot.

This post will show exactly how to tie the Uni knot for the most common two connection needs:

  1. Line-to-Hook/Lure (known as “Uni Knot”)

  2. Line-to-Line (known as “Double Uni Knot”)

Plus, we’ll cover the simple adjustment needed when tying the Uni knot with braided line.

Important Note: Braided line has a much lower friction coefficient compared to mono/fluoro, so all knots need to be slightly altered to adjust for their lower friction.

Finally, you’ll be able to see a video showing exactly how to tie both connections and you can even download a free single-page guide that you can print out in case needed.

Traditional “Uni Knot”

When tying a hook or a lure to the end of fishing line, there are an absolute ton of options.

And the Uni Knot is a very popular choice because it’s quick to tie while also having a high breaking strength.

The fact that it can be applied to line-to-line connections is an added bonus.

Pros of the Uni Knot

  • Quick to tie with high breaking strength
  • Can be used on almost all types & sizes of lines

Cons of the Uni Knot

Steps to tie the Line-to-Hook/Lure Uni knot:

1. Thread line through hook/lure eye

Double Uni Knot (Line-to-Line)

For saltwater anglers, the most important knot of all is the line-to-line knot used to connect the fishing leader to the main line.

This connection is so important because anglers typically use the lightest line possible on their reel to maximize their casting performance while using a heavier leader to be able to withstand the sharp mouths of the fish that they are targeting.

In many cases, the breaking strength of the leader is twice as strong as the main line, so the line-to-line knot is going to be the weakest link in the system.

And of all the line to line fishing knots, the Double Uni-knot is one of the most popular of all.

Pros of Double Uni Knot

  • Quick to tie with high breaking strength
  • Can be used to connect almost all types & sizes of lines

Cons of Double Uni Knot

  • More bulky than some other options (FG knot)
  • Not as strong as the FG knot

Double Uni Knot Directions

1. Overlap leader and mainline with tags going in opposite directions

2. Grab onto the midpoint of the overlapped lines with left hand

8. Pull on the tag end of the braid to tighten Uni knot coils

The tag end always needs to be pulled parallel to the main line for the knot toseat properly, otherwise the knot does not yeild its correct strength or may come loose

Two things that make it better. Moisten mono knots with saliva before tightening and pull tag end to remove any slack in that side of the knot before clipping. You’ll end up with a sleeker, prettier knot.
