This article is about the knot. For the play by Athol Fugard, see Blood Knot.

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. The principal drawback to the blood knot is the dexterity required to tie it. It is also likely to jam, which isn't a concern in fishing line, which is no great loss to cut, but may be a concern in normal rope.

In tying the blood knot, the two lines to be joined are overlapped for 6-8 cm with the short ends of the two lines in opposite directions. The short end of one line is then wrapped 4-6 times around the second line and the remaining portion of the first short end brought back and passed between the lines at the beginning of the wraps. The short end of the second line is then wrapped 4-6 times around the first line and the end of this line brought back and passed through what is now an oval space between the first wrap of each set.

Blood knot step by step

The above method has been called by Stanle Barnes (Anglers' Knots in Gut & Nylon, 2nd ed., 1951) "outcoil", and is contrasted with the method that resembles the finished knot from the start, "incoil". The images here are incorrect to present the finished knot as having its free/"tag" ends go from the center of the knot to the extreme ends; they in fact will immediately coil around the standing parts towards the extreme ends. In fishing line, and in other material if not deliberately set snug and maybe re-set after some initial tensioning, the outcoil form will transform into the incoil form.

The lines are moistened and the wraps tightened by pulling on the long ends of the line. This causes the wraps to tighten and compress, creating 2 short sections of 'barrel', which look much like a 'hangman's knot', that slide together. The short ends of the line are then trimmed close to the wraps, or one of the ends may be left intact to be used for a second fly or lure, called a 'dropper.'

Novel structural and functional mode of a knot essential for RNA binding activity of the Esa1 presumed chromodomain.

Shimojo H1, Sano N, Moriwaki Y, Okuda M, Horikoshi M, Nishimura Y.
Journal of molecular biology.J Mol Biol.2008 May 16;378(5):987-1001. doi: 10.1016/j.jmb.2008.03.021. Epub 2008 Mar 19.
Chromodomains are methylated histone binding modules that have been widely studied. Interestingly, some chromodomains are reported to bind to RNA and/or DNA, although the molecular basis of their RNA/DNA interactions has not been solved. Here we propose a novel binding mode for chromodomain-RNA inte
