DOUBLE CONSTRICTOR KNOT

Purpose

The basic constrictor knot depends for its security on the diagonal knot part
lying firmly across the entwined knot parts beneath it, like a helping finger on a

half-completed shoe lace tie. When the diameter of whatever is being bound is

large, the basic knot is less effective. The remedy is a double constrictor knot.

Tying #1

Begin as for a rolling hitch but then tuck the working end as shown (figure 1).
Tighten the knot (figure 2).

Tying #2

When the end of the foundation is accessible, it is possible to tie this knot in the
bight. First make a clove hitch (in the bight) and rearrange it by moving the

upper end to the extreme left (figures 3–4). Pull out a bight, impart half a twist
and slip it over the end of the foundation (figures 5–6).

Knot lore

The method of tying a double constrictor knot in the bight first appeared in
Knots (1990) by US master rigger Brion Toss, a member of the International

Guild of Knot Tyers.
