That's the baby!
Another joy of this knot is that the hook ends up where you first set it on the line - so you can tie really short hooklengths if you want to.
It's also THE best knot for hooks, because both standing part and tag are trapped by ALL the turns of the whipping. Tis the muttz for spade-ends as well as eyes.
BUT you must tighten gently, and lubricate the knot well (spittle, proprietary knot lube, glue or varnish), otherwise friction can generate enough heat to damage it.
Any chance of a link to the site, Paul? - It's the first one I've seen that attributes the right knot to Mr. Domhof's name!
