Another variation suggested by Dan
Lehman – this time a simple method of
Figure 3a securing the tail from potential Figure 3b
movement.
This structure was published in ‘Knotting
Matters’ issue #19 (1987) at page 2 by
John Smith. It is also ‘TIB’(Tiable in the
Bight).
The geometry of the core (nub) is
structurally the same as #1017 (Anglers
loop) but the loading profile is
completely different – there is no
functioning nipping loop.

Figure 4a This simple method of locking
the tail has long been known.
A disadvantage of this method Figure 4b
is the fact that the strangled
double overhand knot
occupies space within the eye Collar
and hence can cause unwanted
interference. It can also be
Nipping difficult to estimate the length
loop of free tail needed to tie the
strangle.
