Good Idea, Lasse, ...
Although one might as well simply ask for actual uses of any knot
--nevermind whether it might be regarded as "new". At least in
some cases, I think that simply getting
field data, as it were,
will be helpful.
When I use a stack I just slip the loops off and leave the knots in. When done with printing I move the loops back on and, when needed, tighten them by tying a slipknot, (the slipped version of the thumb knot,) and tie the loop around the string holding the stack, with a half hitch.
(Your words were pretty good, and thanks for the picture.)
Why not knot these binding loops with some friction hitch,
to slide snug/open as needed, with anticipated adjustability?
I have a friend who was looking for something to replace the rubber
bands with which he bound together video & audio cassettes for his
video business, and I'd collected some venetian blinds and other assrtd.
cordage for this (but his need seems to have diminished).
My thought was some more secure variant of the Rolling H., and some
stopper in the hitched end; make up maybe 2-3 lengths to accommodate
expected needs, and he can have the loops at the ready, hanging on a
nail or somewhere.
On my own, I've long heard of the UNneed of the nevertheless always included
(in general knots books) Sheepshank, and hence wondered at its longevity
therein. But a novel use occurred to me: use it to
widena rope at
some point of personal bearing (e.g., for a rope to be set over one's
shoulder in carrying a weighted pale) or even to fashion a sort
of temporary handle for pulling on a line (though this is more
easily done by making a multi-eye loopknot).
It's unlikely that the first use can be effected for any extant pale
handle, as that will likely be sized too small to give the extra
line needed to form the knot; but if one's making the attachment
anew, the addition can be provided.
The Pile Hitch (#1815--and elsewhere) has been advanced as a better
alternative for uses of the Marlinespike H. (#1789), and I think
that Brion Toss intends to so present it, in his impending new book
on knots. (For a more secure hitch, simply make a full turn with
the bight before putting it around the object--i.e., bring it
around the ends from the opposite side and then place it as usual.)
Back to the point about actual uses, although in reference to Ashley
this will appear "new", the Seizing Hitch (#3390) is often used as
a mid-line binder in commercial fishing gear. It's the same form as
the Groundline/Picketline H., but tied in reverse, where the Half-Hitch
components can be individually set very tight, the first holding
well enough to enable forming and setting the finishing HH.
(And, for a more secure binder, simply make the 2nd HH a full round
turn with double tucking (like finishing common whipping), which
takes a bit more care in working tight).) There are some other like
hitches that are employed similarly; sometimes this Seizing H. has
HH.s fore & aft. Or a Clove H. is tied, with the end leading to
a HH on the other side of the initial HH of the Clove, which makes
a knot that could be seen as the Seizing H. with an embedded HH.
