Hi Alan, it's been a while since we've seen a simple, yet effective lock for 1010, like this one, in the forum.
Very smart to push a returning bight leg, through the nipping loop, wrap around the loop, then feed the working end through this very bight and down through the collar, forming an unknotted, shaped eight, returning structure.
But is there a merit coming out of this bight tucking?
Absolutely, since it adds three rope diameters inside the nip, and it is not at risk of being sucked through the nipping structure, because the final toggle locks down the bight and the whole knot structure.
I believe it has a taste of the simplicity of Scott's locked technique! I noticed that the cowboy variant is not TIB, but there is a way to make it TIB.
The first impression is very promising, i' m waiting to see its response to heavy strain in order to qualify it as a secure, jam proof, configuration!
