The Blood Knot

This knot is used to join to lines of similar size together, also used frequently by fly fishermen tying there own leaders.  The knot strength is between 95-100% of the line test.

1)  Lie the ends of the two lines against each other, overlapping about 6 inches.  Take 5 turns around one line with the end of the other, and bring the end back where it's held between the two lines.

2)   Repeat by taking 5 turns around the other line, bringing the end back between the two lines. These two ends should then project in opposite directions.

3)   Wet and work the knot up into loops, taking care that the two ends do not slip out of position.

4)   Draw the knot up tightly and clip the tag ends carefully.
