Blood Knot
One of the best knots for splicing two monofilament
lines of similar diameter — or for joining two
dissimilar-diameter lines by doubling the lighter of
the two.

(1) Overlap the two parallel lines by 12 inches total.
Take five wraps on one side and pull the end back
through between the two strands.

(2) Repeat on the other side, pulling the other end
through the strands in the opposite direction.

(3) Pull the two tag ends slowly to gather the knot,
and

(4) once gathered neatly, pull the standing line to
tighten the knot. Trim the tag ends.
Surgeon's Knot
This easy-to-tie knot is popular for joining a heavy
monofilament leader to a lighter monofilament
main line.

(1) Lay six to eight inches of line and leader parallel
and overlapping.

(2) Using the two lines, tie an overhand knot.

(3) Proceed to tie a second overhand knot.

(4) Pull both lines in opposing directions to gather
and tighten the knot. Trim tag ends.
