Half blood knot see three and a half turn clinch knot.
Half hitch: not particularly useful in itself; however, the half hitch does
form the basis of many other knots.
It is formed by making a bight, perhaps by looping a rope around a post
or other object, bringing the working end around the standing part to
take a partial turn (figure 72), and then pulling the two ends in opposite
directions so that the half hitch tightens. Do remember though, that the
half hitch will not hold on its own and needs to be finished off either by
making the ends secure under tension, or with another knot.
Half hitch coil see coiling.
Hangman’s knot or Jack Ketch’s knot: a very strong noose, specifically
designed to withstand a heavy and sudden shock loading. It does not have
a good sliding ability however, and therefore needs to be adjusted to the
required size when being formed.
