What is a figure 8 knot primarily used for?

The figure 8 knot is primarily recognized for its utility in creating a secure loop at the end of a rope, making it particularly effective for anchorage. This loop can be used to attach the rope to various objects or for climbing purposes, ensuring that the knot does not slip under load. While it can indeed serve as a stopper knot in some contexts, that is not its primary function.

Many knots can act as stop knots, but the figure 8 knot's design and reliability make it especially popular for securing a rope to a harness or securing an anchor in climbing scenarios. Its structure also contributes to its strength and ease of untying after being loaded, which is critical in emergency situations involving firefighters.

Understanding the versatility and primary uses of different knots, such as the figure 8, is important in firefighting and rescue operations, as it helps ensure safety and effectiveness in various scenarios.
