This consists of a bowline on a bight (Knot 16) with one short 41
standing part spliced around one of the eyes. The other standing
part is made fast and the challenge is, to untie the bowline on a
bight, without hauling the standing part through or releasing the The Untiable
splice. It is not impossible and a clue to the method used is given
Knot
in the introduction.
Method
There are no set movements to be made. The knot is kept loose
and with the standing part taut, the whole is tumbled over and
over towards the end of the rope. In this manner the tums of
which the original knot was composed are transferred to the
standing part and the last turn, into the eye of the splice itself.
