this is another adjustable grip knot i find useful.  it's very similar to a taught line, but the end is make like a consrictor knot instead of a another half hitch

I'm rapidly becoming a fan! The knot seems to simply do just what I need of it: slide or hold just when I want.

   I understand one s enthusiasm with a knot mechanism : a constant source of joy for the knot-tyer. However, I have to add that there hundreds of similar knot mechanisms, able to "slide or hold just when we want ". The possible " Adjustable Grip" hitches are perhaps the most numerous set of knots, and, of course, we know and use just a few only of them. One can say : I have found one knot that "simply does what I need of it" , end of the story. Most knot users do exactly this. Or, he can ask himself : " Is there any other knot that can do even more, much better ?" If he falls into that trap, he becomes a knot tyer... and me, personally, does not know if there is any way to free himself from this, ever.
   There are many "occupational knots" used by specialists that are meant to function as adjustable hitches : by climbers and arthroscopic surgeons, for example... Knots that are used as one link of bends, or as hitches, can also be used as adjustable grip hitches, if they grip the straight tensioned line hard enough - I guess that many fishing knots can be transformed and used in a similar manner. It would be nice if there was a systematic presentation of all those knots, but I am afraid that the present knot tying community has not reached the critical mass needed to be able to do what has to be done.

Hi Urfin,

Great knotty work, and very beautiful photos!Thanks.

The knots that you to show also to me seem those that have been discussed.
Handling with these 4 versions of the knot, when I decided to simplify the knot to the maximum (thus avoiding adding any additional wraps that usually are added  to increase the grip), I realized that fundamentally the Adjustable Grip is a hitch, around the SPart of which,is provided a Groundline hitch:

http://en.wikipedia.org/wiki/Groundline_hitch

If you note, with regard to 1(the original AG)and 2(AGR (orRAG)),the groundline hitch around the SPart is loaded on the contrary from the leg of the loop adjacent to it, with respect to the knot linked by me above;while, with regard to 3 ("Luca's Variation"? .. oh .. oh .. thanks!But maybe it's more appropriate"misunderstanding variation",and for 4"Urfin Reversed misunderstanding variation"!)and 4,the Groundline is loaded in the same way of the standard Groundline by the leg of the loop.
Now, if 1 and 2 are normally used respectively: 1,for a normal loading around a pole thin enough to make sure that the two legs of the loop remain almost parallel (loading the "inverted" Groundline lenghtwise respect to the SPart to which it is wrapped);and 2,for the mid air loading around an object much larger than the diameter of the rope,so that the two legs of loops diverge with a very wide angle(loading the inverted Groundline perpendicular to the SPart),and if 1 and 2 are better than 3 and (perhaps!) 4, for these two different tasks, and I think so, if only because they are considered as knots recognized and experienced,then I wonder (a little off topic (and of course I'm not asking only to you,Urfin))if the reversed Groundline hitch is actually a hitch better[in perpendicular and  lenghtwise(both lenghtwise directions?)loading] than the standard Groundline.
 EDIT:Although, on second thought, maybe it's a silly question, because the task of a "pure" Groundline Hitch is different from the task that has a Groundline hitch(reversed or not)  applied to Spart of an Adjustable Grip hitch.

                                                                                                              Bye!

You're right that was not informative. I had in mind (and neglected to describe) the following behaviour: when the object is not very large and you tight the reversed AG loosely so that the legs of the loop form an acute angle, it's possible to simple pull on the standing end and the loop tightens like a noose (depending on the material it might need a little help moving the knot). When it tightens and gets close to the bound object it switches to the standard friction hitch mode of operation. This feature seamed to me very convenient and together with the ease of tying (much faster than Blake for me) made me enthusiastic about it.

I've only used the Groundline hitch (and its beefed up version, I think it's called Ossel knot) to hitch to a thicker line:

This maybe has to do with my silly question which I wrote above,I think;the knot used around the standing part of the hitches we've talked about, in their shape is,however,like a Groundline hitch(if you reduce it"to the bone"), in any case I thank you, because I did not know the variation you speak: is this?
