What is a figure-eight on a bight knot used for?

• A. to tie around an object
• B. as an anchor knot that creates a single loop that will not slip
• C. to stop the rope end from moving through a device
• D. to secure the loose end

Answer: (B)

This knot is about creating a fixed, non-slipping loop. By tying a figure-eight on a bight, you form a single loop that stays put under load, which is exactly what you need for an anchor. The loop won’t slide along the rope or through the anchor, making it a reliable anchor knot to attach gear or another rope. It isn’t meant to stop the rope end from moving through a device or to secure a loose end—that’s a different function handled by other knots. So the figure-eight on a bight is best used to produce a stable, non-slipping fixed loop for anchoring.
