22 SLIDING FIGURES OF EIGHT
This simple bend provides the same services as a Carrick Bend in that it securely
joins two lines of unequal thickness and remains easy to undo.
The working ends of each rope are laid side by side in opposite directions. Each
is then used to form a Figure of Eight knot about the standing part of its sister
rope, the latter being enclosed by one turn of the Figures of Eight (it doesn’t
matter which). These knots are worked tight and slid together. To undo the knot
the working ends are simply pulled apart to slide the knots apart allowing them
to be undone.
