When ultimate power in a binding knot is required, the double
constrictor, the best of all binding knots, is the answer. It has
been compared to the grip of a boa constrictor. When the
diameter of whatever this knot is tied to is large, the basic
constrictor knot (see page 73) loses some of its strength—
and thus the double constrictor would come into play. It can
be used, for example, as a substitute for hose clamps. With a
short length of cord, the double constrictor knot works great
to hold a sack without a drawstring closed.
