The gripping cat.
There is a lot of slide and grip structure available, some were discused at large in this forum.
Here is my offer.
I have presented a first version and utily of this structure in this thread;
http://igkt.net/sm/index.php?topic=4830.0Trys ans tests lead me to this form of slide and gripping hitch.
Slick aluminium pole, wood, and rope were put to the test.
I my view it's a very tight hitch, here it's a 3 wraps around version.
Anyone who can tied a cat's paw is able to achieve a good result.
There is a how to do photo; the cat's paw needs to be well place before putting tension with both ends.
It is also easy to loosen up pulling the paw backward with the thumb.
A stopper (half knot with both working ends) can finish it up.
Please tied it and test it before sharing your view.
