With the working end, begin to trace, or follow

the lead of, the first figure 8, as shown in the
photograph.

It is not only a strong and secure loop but easy to visually

inspect for correctness. The working end follows the path of
the rope through a figure 8 that has already been tied, thus

the name. The figure 8 follow-through is no more than a
figure 8 loop (see page 16), but it is tied differently—in this
case the loop being often tied around an object, most often

the climber’s harness. Sometimes called the Flemish bend,
it is not a bend—the Flemish bend is another name for the

figure 8 bend, a knot used for tying two different ropes
together. Before trusting this knot to save your life, leave

enough working end to back up the knot with a stopper. The
double overhand (see page 42) is an excellent choice. The

figure 8 follow-through may also be used by campers and
boaters, typically in situations where someone’s life is not
on the line.
