It’s FG Knot time again!

Yep… the braid-to-leader knot that has continually shined bright in our fishing knot strength contests is back…

But this time it’s to address some problems with the FG Knot.

Here’s the deal:

Now that our original “Fastest Way To Tie The FG Knot” has over 2,000,000 views, we’ve heard from many anglers who have had some issues with this knot.

In particular…

  • That the FG Knot doesn’t work well with certain fishing lines (true – see 0:29 mark in video below)
  • That the FG Knot doesn’t work well when the mono/fluoro is weaker than the braid (true – see 0:54 mark in video below)
  • That the FG Knot was responsible for losing a lure because the knot was cast through the guides (true- see 2:04 mark video below)

Here’s the specifics behind the three core issues that anglers have been having with this great braid to leader knot.

What if you put a dab of Super or Gorilla Glue on the first loop?

Luke and members I wanted to share a different way to tie the FG knot. Luke maybe you could try it and then test it out with your method and see if there is any strength loss by using this method. I have not fished with it yet but I have to say for me it is way easier to tie. I found it on YouTube by a guy called Rad Reeling Fishing. I have seen someone else on YouTube show how to tie it this way but he was not as clear to me. Tying it this way does not require any tension on the braid. I practiced tying it with 50 lb braid to 80 and 60 lb fluoro. Then used 30 lb braid to 80, 60 and 40 lb fluoro. I then tried it on 10 lb braid to 20 lb fluoro. It worked every time. I put serious pressure on every knot and they all held. I had a hard time tying the FG knot on small diameter lines with your method and they are what I use the most. Please tell me what you guys think of it. Also I feel that I could tie this knot on the boat with little problem. We will see. Also thanks for this video cause I to have lost lures and had given up on using it.

Luke or Joe, If us anglers should avoid casting knot through guides, how long of a leader do you recommend. Thanks

Ron

I’ve been using the FG not for a couple of years now with good results. I use if for surf casting w/bait. 30# braid and 50# mono leader (~20 feet long) and 4 to 6 oz. pyramid sinker. Of course, the knot goes thru the guides – the main reason for the leader is the absorb the shock of the cast. The only time I had an issue was once when reeling it in – I noticed the FG not was starting to fray and had a loose end of braid. I retied it and all was good. There were a few times when I had a casting reel “bird-nest” during the cast – the reel came to quick stop and the 4+ oz. of sinker and bait did not. The braid was what failed, not the knot.

IMO the biggest benefit of the FG knot is how smoothly it goes thru the guides. I’ve tried he double-uni, Alberto and Albright knots and the biggest problem with those is when you double over the 50# mono you wind up with a BIG FAT knot. I can feel the knot “clicking” thru the guides when I cast and it tore an insert out of a guides one time (but it was a cheap rod).

With fishing bait, casting isn’t that frequent. Maybe 5 times or so and hour, at best? I could see where constantly casting lures could put wear on the know going thru the guides 30 times or more and hour? But I think its the best for long casts with a heavy, long mono leader and braid main line. And if you check the condition of the knot now and then, there should be a problem.
Thanks!

I agree with one of the posts below that asked about line diameter vs lb. test when it comes to needing to use greater lb. test of the mono than the braid. We are talking essentially the same thing since typically the greater the lb. test the greater the diameter. And since this knot depends on digging into the mono for its strength, the larger diameter mono will have deeper grooves in it versus the smaller diameter mono thus making it the stronger knot.

Hey, I’ve watched the videos on the FG knot and read the comments. Please help me understand what is meant by “protecting the braid”. What are we protecting it from? Thanks.

Peter Maki

Good information. It makes sense after watching the video

Russ Gardner

Can adding a drop of glue to the knot help? Long leaders means casting though line guides!

Emily Gleason Tita

Thank you so much for this video definitely explains why I’ve lost so many lures!! I was using braid to Mono however doing 20/21 coils and casting through the guides! It’s possible that 200 of those 2000 views are me trying to figure out what I was doing wrong! 🤪Thanks again now my FG KNOT will be salt 💪 and my lures will have fish on them instead of sitting lonely in the grass and mangroves. 🤓🎣

Have had a couple of lures fly off during casting. Used 30lb power pro with 30lb floro. After first time thought knot was not cinched tight enough. Second time I switched to surgeons knot. Use bait caster reel and use heavier line to keep it from digging into spool while fighting bigger fish. Thanks for all your helpful info.

Dennis Krausman

My biggest problem has been with 10# braid with 15 # floro when using the Super Slick 8 strand Power Pro. Almost every failure is with the Super Slick not the normal Power Pro.
I can cinch it to hold, but it takes a little extra focus.

2nd biggest reason for failure is not inspecting the knot after repeated outings. I follow the IAF approach, inspect after failure.

Jason Good

I also have problems with the knot failing on the closing stitch. I agree it is a strong knot. I have pulled in a couple 10lb redfish on it. But my personal experience is that it will eventually fail because of the wear on the closing stitch, especially if you continually reel it through the guide.

Michael Danek

Problem # 4, the half hitches unravel. They have to be very tightly tied. When snapping jigs off the bottom aggressively, they are especially vulnerable to unraveling. Good video that agrees with my experience, i.e. it doesn’t work very well if the leader is less strong than the braid. Although, I’ve thought that the problem was more oriented on the relative diameters rather than the relative strengths.

MICHAEL Drozdowski
Member

That’s exactly how I had the FG knot unravel twice before I lost confidence in my ability to tie it and went to the double uni. I had even been tying 4 or 5 half hitches at the end and it still failed. Plus, for me, the FG knot is very difficult to tie out on the water.

I don’t tie it on the water , either, I just put that rig away and use another. I have learned a change to the video that makes it easier to tie a reliable knot. I tension the braid as in the video, but wrap it around a Nite Ize twist tie which grips it well, and loop that through my belt loop. So I’m tying the knot from above and my glasses can give me a good focus on it, and it won’t slip from my teeth. Tying it as I describe results for me in tighter, more even, weaves and gives a good position for finishing the knot. BUT, if the half hitches are slipping, it does not stop that. Really tight half hitches, maybe just a touch of CA glue on the half hitches, might fix it. With lighter leaders I simply use the double uni, too. The advantage of the FG is with heavy leaders, not needed for the lighter ones where it is most likely to fail. OOPS, forgot to leave my name and don’t know how to get that screen again, Michael Danek

MICHAEL Drozdowski

Don’t all the hoops someone has to go thru to tie this knot make you wonder if the extra 20 or 30% strength is worth it? I’ve never had the double uni knot fail on me. I’m not at all trying to throw shade on Luke’s contentions about the FG knot, I guess like everything else in fishing, it comes down to what one is comfortable with and what works for them.

If you take the FG not and dab a little super glue to it all issues go away!

Some, not all. If it is sloppily tied, especially weaves loose or not properly “proofed” after tying, it will fail even with super glue.

I always put loctite superglue on my FG knots. Helps protect knot longer casting knot through guides.

Last spring while fishing near Lostmans river I hooked an 8′ Bull shark. I was using 65lb spider wire altra cast line to 100 lb mono leader. The FG knot held up for over an hour under maximum drag. It made a believer of me and my fishing buddy of this knot.

James Bear

I only target big snook fishing around bridges at night using lures. I have been using the FG knot for about a year now, no failures to date. The key is to take you’re time and tie it right. I like this knot because it’s the smallest knot that can go through rod guides. I make 200 cast a night, no problems, 30 pound braid, to 50 pound flouo leader.

My knots are always throw through the full rod length. Never any issue with it ? If I couldn’t run the knot through the guides I wouldn’t be interested in using it…..

Luke –

I have had a problem with the bitter end of the braid used in the FG knot untying. I followed your instructions for tying it off with half-hitches, and have used some other recommendations for more nd different end knot schemes.. After casting for a while, I can see the half-hitches starting to untie from going through the guides. Any solutions? I tried using superglue to hold the half-hitches, but it either “blobbed” or affixed me to the line. Any tips on superglue usage? In addition, you recommend not using it when casting. However, isn’t one of the of the main features of the knot that it slips through guides so easily, making casting more efficient? This his especially true when surf casting (either bait or lures) and you have get out quite a ways.

Bill, I like to use super glue. I apply it sparingly to the whole knot l. I use the old style black tubes with the long plastic spout. I just get the sides of The spout damp then drag the knot over it as I rotate it. This process makes for ver little excess glue. Seems like a lot of trouble but I think it’s worth refinements to make it work with confidence . Just a tidbit here- I’ve learned to carry a 2” strip of Velcro to hold the mainline in my pocket applying tension on the rod tip while tying in field or boat. I can. Re-tie pretty handily now anywhere using the wrap method presented in the SAlt strong video- my opinion Best way to tie it consistently

Michael Danek

Good points. Try very very tightly tying the half hitches after a very aggressive pull to set the knot, and add a couple more half hitches. The knot really works from actually embedding the braid into the leader. Ty one that you think is really done well, and cut it apart. Note the deformation of the leader. That is the strength of the knot, but it will fail if the braid comes loose, as in the untying of the half hitches you mention. My solution has been to really tightly tie the half hitches.

I love this knot and never have had an issue with it. As mentioned by others, cinch it and test it before cutting the tags. It’s not that hard to tie after you’ve done it several times. If it’s been awhile, I’ll watch the video to refresh my method. Thanks for the video Luke!

John Dunkhase

I’ve used it consistently since seeing on Salt Strong. Lost my first tarpon in Mexico with it! Bummer! Still using it though. Now I’m a lot more careful about tying it and checking it. Would a little head cement from fly tying solve the wear problem? I tried it and it seems to help.

MICHAEL Drozdowski

I tried the FG knot a few years ago based on watching the SS video on how to tie it. I use 10# braid and 20# fluorocarbon leader material. I never cast lures with the knot going thru the tip guide. I have lost lures in the past and when I retrieve the line, all I had left was the braid, so it unraveled somehow at the knot. After losing several lures, and given the relative difficulty in tying the FG knot, I went to the double uni knot and have never had a problem with it, i.e., losing a lure or a fish because the knot failed. I’ve even on occasion been hung up so bad I had to break it off and it has always broken at the lure connection to the leader, not the double uni knot.

I wish you guys would quit telling people that you have to use stronger monofilament than the break. That is absolutely, categorically, 100%, fully wrong! My standard setup on all of my trout rods is 30 lb braid 220 pound fluorocarbon. I use only the FG knot to make the splice. I have never, ever at, at any time, had any problem with that configuration.

I use the knot for braid to braid with one touch of super glue and never have any problem. Also use it regularly for 20 lb braid to 10 lb mono or flou. Never a break or slip for me.

I use 50 lb braid joined to 80 lb fl or 100 lb mono. Put swivel in a vise and locked down the reel backed up and it pulled apart . tried it again and again always pulled apart . My ends are always tightened w pair of plyers and and or a vise . give me a uni knot and lock it and it will hold all my weight leaning against it … Love the shape Of the FG but can’t trust it with heavy line ..

Joe Chamberlain

Luke, a minor point. you touched on this earlier but it was related to cinching the FG knot down before cutting the tag ends. Very true. But it’s worth stating that if it’s not cinched down properly it will slide right off the mono or flouro.
Great tip on fewer wraps vs too many. I didn’t know that. Thx

I’ve been using the FG Knot since discovering it through your video when I first started fishing and I’ve had no issues. I do cast it through the eyelits but only the first 2 because I feel I lose distance if it cast through more then that. Once it FAILED several times but I later discovered the rod tip had a tiny crack that was not easily visible.

I use 30 los to 20 iva fluoro.. when u say it doesn’t work heavier to lighter line u mean the lbs test or the diameter of the line?

Anthony Scot McGallicher

I’ve been using the FG Knot since I discovered it through this platform, and have not had any of these issues. I’ve fished multiple trips on the same leader with the same knot holding up. I actually use 10-20lb braid, with a 30lb mono leader and have had no issues whatsoever. In fact, the ONLY time I’ve had issues with the knot holding up is when I haven’t tied it exactly as Luke shows – however, I test the knot strength before throwing it out with a lure/bait, and the only times it’s had issues is when I don’t tighten it before cutting the tag ends (Luke stresses to pull the knot taught before cutting tag ends, which has been the trick for me). I’ve cast it through the eyes on the rod many, many, many times and have never had the knot come loose. I easily landed a 36″ Tarpon on 10lb braid to 30lb mono leader while in the Virgin Islands. It’s gotta come down to how the knot is tied, in my opinion. Until I find a better knot, I imagine I’ll be sticking with this knot for quite some time. Cheers and tight lines!

People need to check their knots ,at least after each trip to be sure it is still viable. I think the problems we have with tying the knot make us reluctant to retie.

Mark Garcia

Hi guys,
I used the FG for the first time while surf fishing for Rooster fish and big Jack Crevalle off the Pacific coast of Mexico. 6 fulls day of casting and landing some big fish, I did not have to retie one time! Take your time and follow the instructions exactly and you will have no problem! Thanks Luke and Joe!

Nice video, Luke, although the second point in the text contradicts what is in the video. It looks like it was inadvertently reversed.

If you bring the knot just a few inches past the rod tip, the knot hits the guide with more force than if it is much further down toward the reel. If it’s there, the lure being cast has gone far enough from the rod tip to facilitate the passing of the knot through in a fashion (a straighter exit) where it rarely even touches the guide. Do a slow-mo video of this and you’ll see. Your fans will like it too.

This is exactly why I use 20 to 30 feet of fluorocarbon.

I put a single drop of “crazy glue” (I use gorilla) on the lead coil(s) to do just as you suggest “protect” those coils. I cast through guides all the time and have never had an issue using this method.

I caught a 6’3″ tarpon with a fg knot. It was 50 lbs braid to a 20lb leader and it held up perfect. It did however take about an hour to get it in.

Great knot If you tie it correctly, I’m in Southern California fishing BLUEFIN.., I use the FG knot On short 7 to 10 foot leaders exclusively through my 60 pound Rig. Great not take your time I like 22 wraps make sure it lies clean.

Have you tried the ‘Improved FG Knot’? The only draw back is that it takes a little more time. ‘On The Water’ has a good Youtube tutorial on it. I have had the traditional style FG fail multiple ways; including cutting the leader line. I have never had the ‘Improved FG’ fail. The breaks come from the terminal knot or a weak spot in the main line, usually at the reel’s roller.

Dave Otte
Member

Luke, thank you for this information. I ‘sailed’ a few jigs until I finally learned how to tie the FG knot over a year ago, but since then it has never failed me. Ever since I saw Capt. C.A. Richardson suggest using a 4 ft. leader, I’ve been casting the FG knot through they eyes of my rod. I use 10 lb. braid and 20 lb. flouro and mono, without having a failure. I do change my leader about about every other time I go fishing. Just thought I’d share this, maybe it works out for me because I use light gear.
