Strongest loop knot is which?

Strongest loop knot is which?

• A. Alpine butterfly knot
• B. Bowline
• C. Figure 8 on a bight
• D. Clove hitch

Answer: (C)

In rope systems, a fixed loop that resists slipping and distributes the load evenly is key. The figure-eight on a bight creates a strong, secure fixed loop because the knot’s shape locks the loop in place as soon as load is applied. The load is spread along the rope fibers through the figure-eight configuration, and the knot tightens rather than slipping or deforming, which helps prevent failure under heavy or multi-directional loading. It also tends to untie more reliably after being loaded. Other loop knots either risk looseness or movement under load (like a bowline that can back out without backup), or aren’t fixed loops and can slip or shift (like a clove hitch). The alpine butterfly is very solid and versatile, but for a guaranteed strongest fixed loop under the common loading scenarios, the figure-eight on a bight is the preferred choice.
