The Figure of 8 Knot
and Other Stopper Knots

The figure-eight knot is highly valued for its versatility and security. Here are some of its primary uses:

• Climbing: It's often used as a stopper knot to prevent the end of a rope from slipping through a belay device or other hardware. The figure-eight follow-through is commonly used to tie in climbers to their harnesses.
• Sailing: It’s used to prevent lines from slipping through blocks or fairleads, acting as a stopper knot.
• Rescue Operations: The figure-eight on a bight is used to create secure loops for attaching rescue equipment or for hoisting individuals.
• Camping and General Use: It’s a reliable knot for securing loads, setting up tents, and other general purposes.

The figure-eight knot is appreciated for its ability to hold securely and its ease of inspection, making it a preferred choice in situations where safety is paramount.

What are the disadvantages of the figure 8 knot?

While the figure-eight knot is highly valued for its strength and security, it does have some disadvantages:

Disadvantages of the Figure-Eight Knot

• Bulky Knot: The figure-eight knot can be bulky and may not pass through certain types of gear or hardware as easily as other knots.
• Difficult to Untie: Once subjected to a heavy load, the figure-eight knot can become very difficult to untie, requiring significant effort and sometimes even tools to loosen.
• Rope Wear: Due to the way the knot distributes tension, it can cause wear on the rope, especially when used in dynamic or high-load situations.
• Learning Curve: While not overly complicated, the figure-eight knot does require more precision to tie correctly compared to simpler knots like the bowline.

Despite these disadvantages, the figure-eight knot remains a favorite for many climbers, sailors, and rescue professionals due to its reliability and security.

Both the figure-eight knot and the overhand loop knot are used to create loops, but they have different characteristics and applications. Let's break down the differences:Figure-Eight KnotOverhand Loop Knot

• Structure: Forms a figure-eight shape when tied.
• Strength: Stronger and more secure than the overhand loop, typically retaining about 75-80% of the rope's original strength.
• Uses: Commonly used in climbing, sailing, and rescue operations due to its reliability and ease of inspection.
• Untying: Can be difficult to untie after bearing a heavy load.
• Appearance: Symmetrical and neat, making it easy to visually inspect.

• Structure: A simple loop created by tying an overhand knot in a doubled-over section of rope.
• Strength: Weaker compared to the figure-eight knot, typically retaining about 50-60% of the rope's original strength.
• Uses: Often used for simple, temporary tasks where a quick loop is needed, such as securing items or creating handholds.
• Untying: Generally easier to untie than the figure-eight knot, but can still jam under heavy loads.
• Appearance: Less symmetrical and can be harder to inspect for correct tying.

In summary, the figure-eight knot is preferred for situations requiring high strength and security, while the overhand loop knot is suitable for simpler, less critical tasks.
