Tighten the knot slowly by pulling on both
standing parts. As the knot tightens, it will form

the shape shown in the final, upper photograph.
The working ends on the opposite sides of the
knot create a stronger union than when the ends

emerge on the same side of the knot.

Vice Versa

A KNOT USED FOR JOINING TWO LINES TOGETHER
EVEN WHEN THEY ARE WET AND SLIPPERY

Slick lines, such as polyethylene or even strips of wet

leather, can be joined together firmly with the vice versa. A
somewhat intricate knot with quite a few crossing points, it

is not terribly difficult to tie—after a few practice tyings. But
beware: If the two working ends are not woven together

exactly as shown, the final product will lack the security of a
true vice versa, and the knot may utterly fail.
