The Snell Knot is a good knot to choose when fishing
with a separate leader. It can only be used with a leader since it uses
both ends of the line to tie it.
Instructions for tying the Snell Knot
Feed one end of the leader through the hook's eye going
2-4 inches past the eye. Then feed the other end of the leader through
the eye in the opposite direction. Hold the hook and leader ends between
thumb and forefinger. Allow the excess leader to hang down in a large
loop.
Holding the hook and leader in your left hand, grab this
excess leader loop and the part of this loop close to the hook and wrap
it over the hook shank and both ends of the leader toward the hook's
barb. Go around the hook 7 or 8 times, keeping the newly made wraps
contained and tight with your left thumb. Pull the short end of the
leader that is through the eyelet with your right hand slowly, until
the entire loop of leader feeds through it. Be sure to continue holding
the 7 or 8 loops with your left hand so the knot will not unravel.
When it is almost tight, use your
fingernails to slide it up against the eye of the hook. Finally, pull
the short end of the leader and the standing line at the same time to
completely tighten the knot. Trim the tag end.
