It's more like a whipping knot, agree most knots are ueless with wire as they pig-tail even the so-called supple ones.
Cut the wire to slightly more than the required length - say 3ft.
You attach the bottom hook first.
Find the "flat" side - opposite the side where the extra point is brazed on - and pass the wire through the eye so a short tag lies along the shank on this flat side.
Hold this with thumb and forefinger and bring the long end down the shank on the other side, take it around the bend and then whip eight or 10 tight turns, before passing the long end out through the eye; makign sure it all stays nice and tight.
Most wires snug down fairly nicely with opractice.
Then cover it in shrink tube to keep the tuns neat and help reduce damage from forceps/pliers when you're unhooking a fish.
Thread the long end through the eye of the top hook in the same way, so the trace is lying along the flat side, then hold hook in thumb an forefinger take wire around bend, whip up shank etc and repeat process to attach top hook.
Swivel at the top of trace is secured with a lark's head, with a crimp to keep the tag end neat, with the bottom eye/connecting and little bit that ends up poking out beneath the crimp covered again in shrink tube.
It's quite quick when you get the hang of it.
