A grief knot (also what knot) is a knot which combines the features of a granny knot and a thief knot, producing a result which is not generally useful for working purposes. The word grief does not carry its usual meaning but is a portmanteau of granny and thief. The grief knot resembles the granny knot, but tied so that the working ends come out diagonally from each other, whereas a granny knot's ends both come out on the same side. It unravels rather elegantly: as tension is applied, the ropes rotate like little cogs, each one twisting to feed the rope through the knot.
