Designed for splicing a monofilament leader to a fly line. As the name implies, a nail is needed
to tie this knot, although a toothpick or straw can be substituted.
(1) Lay eight to 10 inches of leader and fly line overlapping and parallel to each other, with a six-penny nail in-between.
(2) Using the leader line, loop up to eight
coils back around the fly line, the nail and
the leader. Using the nail as a guide, run
the leader line back under the coils.
(3) Hold the loosely-gathered knot with
one hand as you withdraw the nail with
the other hand.
(4) Pull on both ends of the leader line
to tighten the knot. Trim the tag ends
of the leader and the fly line.
