Knots & Rigging: The Blood Knot- The Perfect Knot for Making Tapered Leaders and Joining Lines
The Blood Knot is one of the best knots to use to join two stands of similar diameter monofilament. It is valuable to the gamut of anglers, but extremely valuable to the fly angler for joining different test lines to create tapered leaders. It is a relatively simple knot to tie with a little practice and... is extremely strong not matter how short you clip the ends.
The knot can be tied in four simple steps and as with anything, take some time to practice this at the dock so you are not learning it on the water and decreasing valuable fishing time.
Step 1: Cross the two ends of the line together and wrap one of the lines around the other three to five times. Once you have done this take the end and put it end of the line though the loop formed but the two lines as shown below.
Step 2: Do the exact same thing with the other end of the line, but take that end and put it though the loop in the opposite direction.
Step 3: Slowly pull the long ends of the line together. I suggest wetting the line when doing this to assure a snug fit.
Step 4: Give the line a tug to make sure its tight and finish by trimming the ends.
