a knot used for tying fishing leaders together; the ends of the two leaders are wrapped around each other two or three times

the most widely used knot for tying two pieces of monofilament with similar diameters together; the best knot for construction of a knotted tapered leader; also called the barrel knot.

combination of two lines of equal tinsel strength tied together. It is used in cases of emergency when no other line is available to replace the diminished spool capacity on the reel. The strength of the knot is about eighty-five percent.

Basic knot for hooks and swivels Boilie Round boiled baits usually attached to rig on a hair. See hair rig.

A blood knot (Barrel knot) is most usefully employed for joining sections of monofilament nylon line while maintaining a high portion of the line's inherent strength. Other knots used for this purpose can cause a substantial loss of strength. In fly fishing, this serves to build a leader of gradually decreasing diameter with the castable fly line attached at the large diameter end and the fly or hook at the small diameter end.

"Blood Knot" is an early play by South Africa's Athol Fugard.
