dunlap (or whoMever), when was that hitch introduced? 15yrs ago?
The hitch, which I like to call "ProhGrip" with a German "ProhKlemm(noten)" match,
was first introduced (as we can know, so far) by HEINZ PROHASKA (hence my "Proh") in an
Austrian mountain guides manual, ca. 1981. Heinz subsequently published this hitch in the cavers
periodical Nylon Highway in 1990, four years before Blake's article about it appeared (as a letter)
in Arbor Age.
Heinz advised the following adjustment of the hitch: should it slip because of stiff rope,
make an extra turn in the lower half (i.e., the part of the coil that wraps TWO dia.s
of rope--hitched line & hitch's end); if it slips because the materials are slippery (but cord
is otherwise flexible), make an extra turn in the upper half (which wraps purely the
hitched-to line).
One can tie this knot with a sling/loop, in a variety of ways, also.

Re knot names: I keep seeing the mistaken references implying that a "fisherman's knot"
is a Dbl.Overhand; no, no, puhleez lueeze, it's a bend composed of two (single)
Overhands that are pulled into each other (and a Dble.Fish. is a similar knot composed
of two Dbl.Overhands; aka "Grapevine Bend").
"Half a Fisherman's" shows half comprehension.
That noose used to tie to rings/'biners ought to be called a "Strangle Noose",
or "Scaffold Knot" (though that's always presented with more turns in the Overhand).
And, frankly, I think a Fisherman's Bend (which <sigh> is a
hitch) would be
a better form of Dbl.Overhand for use here--tad less likely to deform. Just tie
the end to the line with this venerable anchor hitch, end going away; tighten
the knot, draw it down snug to the ring. (A
minimal Blake's (ProhGrip) would
also work (Ashley #1692, fyi).
