When it comes to joining braided line and either mono or fluoro line, we use two basic knots. For light tackle fishing we use the Double Uni Knot (both rank among our top seven fishing knots of all time along with the Pitzen Knot).

Why do we use the FG Knot?
The bad news is the FG Knot is significantly harder to tie than the Double Uni Knot, but the extra effort rewards you with an almost 100% transfer of strength. And it is thinner than competing knots such as the Double Uni and the Albright Knot so it goes through your rod guides much easier.
There are all sorts of instructions on tying it, but the method in this video (which is replicated in the written/illustrated instructions here) is the best. The key to tying this knot successfully is using all your limbs to maintain tension on both lines throughout.
Here below are the written instructions and below that I have embed a YouTube video from Australian fisherman Jason Erlich that most people agree is the best video explanation of how to tie this knot.
FG knot history
The FG knot is a relatively recent addition to the very growing book of fishing knots.
Very popular with Australian saltwater anglers, the FG knot knot was invented by GT fishermen who were getting busted off by giant trevally, one of the world’s strongest fish pound of pound. They also wanted to maximise their casting distance and accuracy, so needed a thin knot that could pass easily through the rod guides.
It’s just popular now in the US and other countries and is also known as the Sebile or GT knot. While it is harded to tie than the Double Uni Knot, the method described here allows you to tie it in less than a minute if you practice it. When you think about the pain of a lost trophy fish that escapes due to a weak knot, an few extra minutes perfection your terminal tackle connections is time well spent.
FG Knot Tool
The other option for tying this knot – if you are having difficult – is to use the Daiichi Seiko Knot Assist Tool, which is 100% designed to help tie the FG Knot.
The tool works is Japanese designed and super high quality. It tightens the braided line and keeps the tension on one end of the leader so it is easy to tie a FG knot without the knot slipping. See below for video instructions on how to use the Daiichi Seiko FG Knot tool.
FG Knot Testimonials
As you’ll read in the piece, the key to this knot is practice. Carl points out he’s taught people who are hopeless with knots to tie the FG Knot quickly and effectively, but it is just a matter of doing it enough times as practice to you develop muscle memory of the required techniques.
