Overhand safety is not required on which knot?

• A. Bowline
• B. Clove Hitch
• C. Figure-Eight Knot
• D. Figure-Eight on a Bight

Answer: (D)

Overhand safety is used to prevent knots from slipping or capsizing under load. The figure-eight on a bight forms a secure loop whose geometry locks in place when loaded, making it unlikely for the tail to pull back through or for the knot to undo itself. That built-in stability means an extra overhand backup isn’t needed. By contrast, other common knots can loosen or slip under certain loads or movements, so they’re often tied with an additional stopper knot for security.
