I found this for the Jansik knot compared to another knot, also saw two versions of how to tie the Jansik knot. This one goes thru the eye of the hook twice, the other went thru 3 times - which might be tough to do with some of the line and hooks I use. This is a comparison of the jansik and the "eye crosser knot" - which won this battle of the Knot Wars.
There sure are lots of knots on the web and some interesting sites that show how to tie them. I've found several versions of how to tie many knots.
