What is the purpose of a figure-eight on a bight?

• A. To create a secure fixed loop at the rope end for attaching a load or connecting to a device.
• B. To shorten rope length.
• C. To stop rope end from fraying.
• D. To tie two ropes together.

Answer: (A)

The main idea is that this knot creates a fixed loop at the end of the rope. By tying a figure-eight around a bight, you form an eye that stays the same size under load, giving you a dependable attachment point. That stability makes it ideal for attaching a load or clipping to a device like a carabiner, harness, or anchor. It’s not about shortening rope length, preventing fraying, or joining two ropes, which is why those other purposes don’t fit.
