finished blood knot

Before the advent of ready made tapered leaders, blood knots were used to join different diameters of line to make a tapered leader. It was the preferred knot because the tag ends come out of the middle of the knot and therefore don’t catch on rod rings or the fishing line.

In coarse fishing, a blood knot can be used in any rig where there might be a risk of line looping back and catching on the tag end left by other knots.
