Which stitch finishes the end of the permanent whipping of a line?

• A. Overhand knot
• B. Lock stitch
• C. Square knot
• D. Running stitch

Answer: (B)

Finishing the end of a permanent whipping on a line needs a secure, interlocking finish that won’t loosen with use. A lock stitch serves this purpose because it threads through the whipping and then interlocks with the wrapped turns, pulling tight to create a stable, resistant end. This prevents the whipping from sliding or unraveling when the line flexes or bears load.

An overhand knot would add unnecessary bulk and can jam or slip under tension. A square knot isn’t reliable for securing the end of a rope whipping and can work loose. A running stitch alone doesn’t provide a true lock and can unwind with movement.
