The Figure of 8 Knot is sometimes known as The Flemish knot or just plain “eight.” Often employed by sailors, this is a fantastic stopper knot.
Below you can see how to tie The Figure of 8 Knot in a simple slideshow.
The Figure of 8 is often used as an alternative to the Overhand Knot.
Of course – in non-loading and situations which are not life threatening, I usually use a simple overhand knot as a stopper knot. In comparison, The Figure of 8 takes more rope and can be slightly more difficult to tie. Bulky in nature of the eight makes it a superior stopper knot. The eight is a pretty strong knot, compared to the simple overhand knot.
When perfectly tied , the Figure of 8 Knot doesn’y suffer from anywhere near as much strength loss or potential to damage the rope as the overhand knot.
