The "X" Knot We're not sure who tied it first, but we came across it on the Location X shoot last year.              Our X guide showed us this foolproof knot, that was not only         surprisingly easy to tie, but is one of the simplest and most innovative knots                          ever for attaching class to shock.        Again and Again! Note: The knot has been tied twice (once with mono and once with fly line and backing). The beauty of this knot is that the angler can back the knot out and put on new shock tippet (after chaffing from fights etc.), without having to re-tie the Bimini Twist... And the knot will still not fail. Click any photo to enlarge.
