Very good instructions and tutorials on this site. Lots of knots and where they can be used.
The Non Slip Loop Knot. Superb. The strongest loop knot you can tie. Used by big game anglers worldwide. Easy to tie, far stronger and more reliable than the old fashioned strangulating figure eight knot that can substantially weaken line. Ultimate Knots
