How to Tie a Reef Knot

The Reef Knot is also known as a Square Knot.
WARNING – There is a warning when using the Reef Knot, in Ashley’s Book of Knots, the Reef Knot has the most skull and crossbones associated with it. We all grew up learning how to tie the Reef Knot, but we were never taught the dangers of using the Reef Knot!

Ashley’s Book of Knots says: “The Reef Knot is unique in that it may be tied and tightened with both ends. It is universally used for parcels, rolls and bundles. At sea it is always employed in reefing and furling sails and stopping clothes for drying. But under no circumstances should it ever be tied as a bend, for if tied with two ends of unequal size, or if one end is stiffer or smoother than the other, the knot is almost bound to spill. Except for its true purpose of binding it is a knot to be shunned.”

What is the Reef Knot Used For?

The Reef Knot should only be used for light duties; a good knot to use for tying up a bundle of sticks, used in a sling to support an injured arm, tying down part of a sail to reduce the sails effectiveness. Never should a Reef Knot be used as a bend (joining two ropes). When heavily loaded the Reef Knot will fail.
