Does anyone know the name of this knot and its' capabilities? I will try to describe it. Called it "Loop" knot in the title as I lack the name of this knot.

The knot is easiest to tie when the lure has some weight. It can be tied extremely quickly and is easy to tie if you have cold or lack dexterity in your hands.

Example:

Take a jig and run the mono thru the eye of the jig and have the tag end about a foot long. Let the jig hang loosely. Therefore having about a six inch long loop.

Hold the non tag end in you left hand and with your right hand loop the tag end over your extended left hand index finger.

Then with your right hand make five or so wraps around the loop of the suspended line. Then insert the tag in the loop formed by your index finger.

Grasp hold of the tag end and pull and the knot tightens about six inches from the jig. Take the non tag end and pull the knot down to the jig eye and pull to tighten the knot.

The knot is much like a uni knot in that may be slipped up the line to make a loop.

Maybe this is just a fast way to tie a uni knot? I just can't visualize it though.

Hmm, not familiar with the knot you describe.  What I consider a 'loop knot' is this:

I've looked at some of the knot tying sites and did not see this knot demonstrated.

The more I think about it this may just be another way to tie a uni knot.

It sure is much less cumbersome to tie that the usual way I tie a uni knot.

Its a Uni Knot.  Much written.... 

From what you are describing, it might be an Orvis knot because of the ability to slide the knot up the leader and back down. Orvis sponsored a competition for the strongest knot because of the need for 7x tippets (1 lb) in fly fishing spring creeks and such. I love the knot and it works great with the braided lines that slip other knots. also, when I go steelhead fishing, I'll tie it on to a bare hook and then pull it up the line and insert some pink or orange or other eggy mix of poly pro yarn and cinch the knot back down. It's a killer and now that I think about it, might work for swimbaits through bedded bass. Then again, we might not be talking about the same knot.

I look up Orvis knot and that is not the knot. Key difference is that for the "Loop" knot (most likely a different way to tie a Uni knot) the tag end is wrapped around on the outside of both of the hanging loops. I wish I had a video of the knot as it would be clearer.

That is the characteristic that makes the knot easy to tie as one just grasps the tag end between thumb and forefinger and makes five or six quick wraps around the hanging loops and then threads it thru the small loop that was formed via ones index finger when the five/six loops were generated.

Thanks everyone for their input.

The knot is a reverse clinch knot.
