Survival courses often include this knot as a means to aid in
the construction of primitive shelters. It works well in light

cord to bind together light pieces of wood, such as when a
kite or garden trellis is assembled, and it holds nicely in
synthetic or natural fiber cord. It is similar to but slightly

less complex than the constrictor knot (see page 73). This
knot is typically tied in short pieces of rope or cordage,

since longer pieces are unwieldy and unnecessary to get the
job done.
