How to Tie a Figure 8 Knot

Besides the elegant look, knowing how to tie a Figure 8 (some might say “a Figure of 8,” but either way is correct) will give you a knot with great utility.  Many climbers choose to tie a Figure 8 over a bowline due to the strength advantage of the Figure 8 (The Figure 8 reduces rope strength about 10% less than a Bowline).  However, the strength of contemporary climbing ropes is so strong that considering the strength of a knot is probably not necessary.  Nevertheless, the Figure 8 is a beautiful knot that will give you strength, stability, and peace of mind for countless uses. 

Here are the fast facts you need to know to tie and use a Figure 8 properly.  The standard of proficiency for tying a Figure 8 is: In any environment, given a sling rope while blindfolded (or in complete darkness), tie a Figure 8 within 30 seconds or less, ensuring that each pigtail is no shorter than a fist and no longer than a fist with thumb extended (4-6 inches).

Figure 8 Use

The Figure 8 is a Class 3 (Middle of the Rope) knot, but it may also be used at the rope’s end (like a Class 2 anchor knot).  

Figure 8 Advantages vs. Disadvantages

Advantages

• Stronger than knots of similar purpose
• Easy to verify it is tied properly in complete darkness (by feel)
• Almost no chance of becoming untied on its own when used with a security overhand knot

Disadvantages

• Not as easy to tie (properly) as a Bowline
• When tied sloppily, can be difficult to check for correctness
• More difficult to untie than similar knots after being heavily loaded
