Why isn't the Anti-Bowline just called a Sheet Bend Bowline?

"anti-bowline" is my term for a subset of  *bowlines*
--by which I mean those eyeknots in which the SPart makes
a loop (circle) that nips other parts and feeds into the eye--
in which the tail enters the SPart's loop from the other side
than it does for the bowline (#1010)
--akin to "anti-cyclone" and relevant "anti-clockwise"
indications of direction.  So, you see that it's primarily
a general classification, not some particular knot
(and that "bowline" is used in three senses : general
of all eyeknots with a central nipping loop; the subset of
those in which the tail enters this loop from the one side;
and the particular, venerable knot that Ashley numbers "1010"!).

But were one to look for one particular "anti-bowline",
I'd say its one in which the tail makes a simple loop through
the SPart's loop, and so unlike any sheet bend.

I like this knot , easy to tie, just like a sheet bend, very difficult to undo, with my soft thin rope

As I've said elsewhere, I don't trust this knot's security
when slack.  But I've some 8mm? marine kernmantle
cord in which a similar knot was tied --symmetric, the
anti-bowline with tail coiling away from the eye, so the
same if loading the tail and leaving the S.Part free--,
and it seems to have jammed well enough.  (It's quite
surprising, from what I've seen of commercial-fishing
rigging, that the tails weren't hog-ring stapled to their
S.Parts --damNear all such things are, gratuitously, IMO.!)

My surmise is that the tyer used this knot in preference
to the overhand loop because it's "PET" ("post-eye
tiable --i.e., one can form the eye and then make the
knot!) and jams satisfactorily.  After the cordage gets out
into the drink and shrinks (nylon) and loses new-condition
slickness, staying tied is more assured.  But one does have
to cross that bridge safely, first.

Very interesting. So if the rope size is big and hard stiff then the knot is  easy to undo by pushing spart as a pole. My rope is  only 3-4mm and very soft and not slippery, so it seems just ok for me.

Size  , material . Load....

Knots can behave remarkably differently in different media:  a rope's
size, flexibility, and surface qualities (including structure--laid
or braided) determine a knot's effect; tape, with its flat cross
section, is quite structurally different than round rope.  Rope can be
silky, slippery soft, or agedly frictive and stiff; it can be steel-like
inelastic or stretchy.  And even with the same qualities, in proportion
to diameter, relative to manual strength large and very small dia.s can
make differences (e.g., it won't be a man who realizes the elasticity of
a mooring hawser!).
