At the posts that follow, one can see all the X ( X : crossed tails ) versions of the Mark s / Hunter s / Shakehands- like knots, generated by retucking the Reef-family-of-knots bases. First come the pictures of the simpler interlocked-overhand-knot bends, where the working ends are not twisted around their standing ends, before they tuck themselves into the central opening of the base.
( The pictures of the X versions of the interlocked-fig.8-knot bends, will follow soon.)
There are two things in this series that are worth mentioning. First, the two versions of the Hunter s X bends, the Hunter s X1 and the Hunter X2 bends. Almost identical, but still different, they look like the Zeppelin X bend in that, although the crossing of the tails introduces an asymmetry into the knot structure, relatively to its parent knot, the two links remain, somehow, symmetric to each other, i.e. we still have a "love bend".
The second interesting thing is the fact that the Shakehands-X bend, when its tails are crossed before they exit the knot s nub, generates two different knots : the known common Shakehands bend, and another strange form, which, for the the time being, I call simply as the "Shakehands II bend". ( I an not aware of any references to this later form, but I have not searched enough, because the name was not of any concern here.) This strange knot seems to be a very secure bend, and I will be surprised if it was not mentioned somewhere, even as a comment to a mistakenly tied common Shakehands bend.
