Double thumb knot see fisherman’s knot.

Double wall: this is illustrated using four strands, held firmly in the left hand with the ends having
been formed, working anticlockwise, into a wall knot (figure 55.1; see also page 187). However,

any number of strands can be used, and it can also be formed by working clockwise. The emerging
strands, which would face upwards in all wall knots, are laid alongside previous bights, which are
followed around until they emerge separately pointing upwards (figure 55.2 has been drawn showing
this flat, for clarity, but the strands should be pulled upwards).

Draw hitch or thief knot: provides a quick release simply by tugging at the working end. It can,

however, prove disastrous. Whereas it is a perfectly efficient knot when being used as a lifeline, it is
essential that the standing part, which is capable of supporting a load – the escaping thief – is not
confused with the working end. Therefore when this knot is being used, as it is by the fire services, as
a lifeline or as a means of escape, extra care must be taken to identify that end (the standing part)

which can support a load.
