Tying the Kreh Non-Slip Mono Loop Knot

No one learns the importance of knot strength until it really matters. In my case, that was after chasing permit with a client for three days, seeing him finally hook a fish — and then watching my poor excuse for a Clinch Knot fail. Twenty-three years later, it still hurts. Now I can just about tie a triple Surgeon’s Loop with my eyes closed, but it’s that miserable moment that reminds me to re-tie any knot that is even slightly suspect.
Fortunately there are tippet-to-fly loop knots that are less awkward to tie than a triple Surgeon’s and just as strong. An important one is Lefty Kreh’s variation of the Mono Non-Slip Loop. This week we show his demonstration of the normal Non-Slip Loop — already a close-to-one-hundred-percent knot — and then the slight modification that makes the knot even stronger.
