I think I know of it, it's granny knot tied by forceps. Blasphemy is adding extra turns or extra half hitches. Our ancestors weighed up what added value.Crac, have you tried the Surgeon knot?
Just wonder if it solves the reef knot problem.
Knot #1025, from Page 187 of Ashley book of knots says this:
“There are always people who believe that if a single thing is good two are bound to be better. So they overburden their knots with extra turns and flourishes. The accompanying knot, which is often shown, is a good example of this, the previous knot being quite adequate, and the latter no improvement over it.”
Knot #1719 “Riggers never seem to tire of adding seizings.”
Knot #1781 ( Two half hitches ), from Page 303 of Ashley book of knots.
"Three half hitches are more than a King’s yacht wants” – Admiral Smyth.
Personally I use the seine knot. Which allows to stitch ( or the loop) to be tightened using the free end, and the knot to be tightened by pulling on the standing end. Because the seine knot is tied around it's self (like a hitch) I don't think this counts as a solution for binding knots. But it's great for stitching a ripped sail or for first aid.
If there is a reef knot problem it lies with the teacher... and maybe a little further a field with our box ticking culture. My system is a 1-2 punch of “Functions” and “Principals”.
"Functions" is for the knowledge part. Function covers What can we do with rope, and ultimately the solutions or ideas I’ve selected. (I'm writing up this part and testing things).
“Guiding principals”, is the understanding of How or Why types of knots work. It's how to read knots.

The reef knot is so easily introduced without the warning of it limits. Which is crazy given how easily it can be tested.
