3. Double Overhand Knot

Also known as: Doubled Thumb or Simple Knot

“Doubling” (taking part of the rope and passing it through a crossing turn or
other element twice) is another basic procedure used in many knots.
Doubling creates more bulk and increases friction, which equates to
holding power. While the Double Overhand Knot is larger overall than a
standard Overhand Knot, its diameter is the same so it won’t prevent the
rope from running through a larger hole.

Uses: stopper, binding, handholds along a line
Pros: quick and easy to tie; less likely to slip than a standard Overhand Knot Cons: hard to untie if
tightened hard
