It is considered inferior to the reef knot, which it superficially resembles.
The reef knot (square knot) is the strongest of this knot family, but it should be noted that this is a very poor way of connecting two rope ends. This is because the knot will undo if a free end is pulled outwards.
The thief knot is so-named because it is supposed to have been used for tying around valuable trunks. On first inspection it looks exactly like the reef knot so if an unauthorised person undoes the knot to look into the trunk, and then refastens the rope with a reef knot, their actions could easily be detected by the owner.
The grief knot is so-named because it looks similar to the reef knot but is very likely to slip undone, causing grief.
