HookRz posted about this knot a couple of years ago and I was recently reintroduced to it. It's a very simple and fast knot to tie, plus I don't need to put my reading glasses on to see what the heck I'm doing. 

You can check it out here; 

 

Nifty. Is this mono to mono only?

I don't fish a leader often, but if I do, this is the knot I use.  Braid to fluoro leader knot and it is super simple to tie and holds very well.

I like it ! ... Now I can return the $38 third  arm assist tool plus the 30 minutes needed to tie the FG Knot  (lol !!)

Seriously , if this Lefty Kreh knot holds at 90% + and goes thru the rod guides using #10 lb. braid to #8 lb. FC leader - then I definitely would adopt it ! I then would try it with #40 lb. braid to #12 lb. mono for my bait cast top water set up ... This could well be the best tip of the year !

No, you can use it for attaching any leader to any mainline.  

Google ‘Seaguar knot’ and you’ll see they are the same thing. Not sure where or when it appeared first. I do know RichZ swears by this knot, and at least for a good spell, Ned K did, also.

This knot was what I used at the beginning of last season and never failed me. Kept hearing about the San Diego jam knot and the Yucatan knot. Switched to the Yucatan knot because I heard good things. First time using the Yucatan I ended up with a squiggley end. I am a pretty good at knots. That was the first knot I think I have had fail. Well that ruined me, took the braid off the spinning reel and haven't used a leader since. Should have just stuck with the Lefty Kreh knot.  

How heavy a braid/mono could one go and have it slip through rod guides? I'm pretty happy with the FG, but would like one that would be faster --for when my hands are shaking!

Man, that looks a heckuva lot simpler to tie than my usual. I may be giving this a try in the very near future.

I don't use superglue on my uni to uni, what's it do for you?

Straight mono on everything until frog time. Then 50 lb braid on one big pole. Not having to tie leaders is glorious. Never had a knot let me down , I just like more fishing and less piddling

scientifically? probably nothing. confidence wise? its everything. 

Lefty Kreh knot is quick and easy, especially while on the water.  Only negative I found is that it is a little more bulky than some of the more time consuming knots, thus giving a little "bump" when passing through the guides.

I wasn’t super interested in till I saw that video, if the tag ends can really be trimmed that close it seems like a much easier to tie FG alternative.

Yep, that RichZ. I believe he made that video after he and I had a discussion online over various connecting knots and their respective strengths a couple years back.

That's a perfectly reasonable answer. 

For what it's worth, saltstrong tested the six turn surgeon knot as #2 behind the FG. It's really fast to tie unless your leader is more like a topshot, then it's probably not a good pick. Small too, at least on spinning-class braid and leader. 

It is on my list to test it on my own lines, but the times I've used it and had a break the terminal knot has failed first. It is subjective but I don't think the 6-turn surgeon can take the same beating that an FG can take.
