Today I received a letter from Fly Fisherman subscriber Jack Miller who said he enjoyed the "2012 Tippet Shootout" by James Anderson in the June/July 2012 issue. Like Anderson, he was disturbed by the weakness of many common knots and devised his own tippet-to-fly knot he calls Jack's knot.
I showed Lefty Kreh, author of Fishing Knots (Stackpole Books, 2007) and two other books on knots, and he said the knot is new to him, and looks like a slight variation of the Davy knot.
"The Davy knot makes the final wrap around the loop while this knot makes the final loop around the two folded lines—I think the newer variation may be stronger but I'd need to test it," Lefty told me in an email.
