Which tool bends ends of cotter pins?

• A. Cotter Pin Extractor Flat End
• B. Long Nose Pliers
• C. Depth Gauge
• D. Tensimeter

Answer: (A)

Bending cotter pin ends is done with a tool that provides a flat, solid surface to form a clean, secure bend without slipping or mashing the pin. The flat end on a cotter pin extractor is specifically designed for this job, letting you press and bend the ends neatly so the pin locks in place. Other tools shown aren’t meant for this purpose: a depth gauge and a tensimeter are measurement devices, not for bending cotter pins, and while long-nose pliers could persuade a bend, they aren’t specialized for cotter-pin ends and don’t ensure a controlled, proper bend.
