Are you aware of the nail knot splice?

There have been a few questions about knots on the forum this past year, so I thought I should bring it up. The knot is especially useful when joining hard material leader sections that differ in diameter by more than about 0.006in. If it helps anyone, I can post a few pictures of the technique, let me know. With the Tie-Fast tool, it's quite simple and makes a clean, smooth knot (even with Maxima Chameleon) that whizzes through the guides on your fly rod. I hope this is helpful.
