Which tool is primarily used for marking rather than measuring?

• A. Scriber
• B. Engineers square
• C. Steel rule
• D. Vernier caliper

Answer: (A)

Marking out lines on stock to guide cutting is the task being tested. A scriber is designed to leave a clear, fine scratch on the surface, creating a visible line to follow when cutting or drilling, and it doesn’t provide measurements. The engineer's square mainly checks and establishes right angles, so its primary role is to verify squareness rather than continuously marking lines. The steel rule is a measuring tool with graduations used to measure lengths, not to mark lines. The Vernier caliper gives precise measurements of external, internal, and depth dimensions, not marking. So, the tool used for marking rather than measuring is the scriber.
