The blood knot is one of the simplest fishing knots of
all and while it weakens the line by around 40%.
Despite the obvious shortcomings it is still one of the
most popular fishing knots for joining heavy fishing line that needs to be
joined quickly.
Simply twist the two lines together then separate the
center and pass one end through the center one way and the other tab end
through the opposite way.
The blood knot is one of the most popular offshore
fishing knots used by sport tuna & GT longliners.
They tie up their 4 millimetre thick 800 pound breaking
strain longlines with this knot as it pulls up easily even on very heavy
monofilament nylon fishing line.
For the strongest results put as many twists in as you
can without causing the nylon to grab when setting the knot.
The maximum number of twists possible will vary
considerably between nylon brands and lubrication used.
