2. Slipped Overhand Knot

Also known as: Slip Knot, Running Knot, Overhand Knot with Drawloop

Many knots can be tied “slipped,” or with a drawloop, in which the working
end is formed into a bight before it is captured by another part of the knot.
Never use the bight in the working end of a slipped knot as a loop to bear a

load: it will not hold. But if the working end of the Slipped Overhand Knot
is left extra long, it can be turned around so that the working end serves as
the standing part, and the drawloop can then function as a simple noose.

Uses: stopper, simple noose

Pros: quick and easy to tie and release; bulkier than a standard Overhand Knot Cons: less secure than a
standard Overhand Knot; not as effective as some other stopper knots
