Reef Knot
The reef knot is very easy to tie. It's just 2 overhand knots tied in the opposite way. If you tie both knots in the same way you end up with a granny knot that is good for absolutely nothing except not holding!
Tying a Reef Knot

The only use I have for a reef knot is for tying reefs in my sail. That's how it pays the rent on my boat. It's not reliable and tends to slip, so you can't depend on it to stay put. It's a pretty knot and it's easy to take apart.
Because it's so easy to tie it's tempting to use it, but IT IS UNRELIABLE, I have to remind myself to use the proper knot instead of a reef knot when not reefing.

Improper use of knots can be dangerous. Know how to tie them properly and what knot to use when. Ropes loose strength where they are knotted. In critical applications make sure the strength of the rope is sufficient.
