An example of a single cut file is which?

• A. Warding file
• B. Bastard file
• C. Two-cut file
• D. Rasp

Answer: (A)

The concept being tested is the difference between single-cut and other file types. A single-cut file has one line of teeth running along its length, which cuts in one direction and leaves a smoother finish—great for finishing work and reaching into tight corners.

The warding file fits this pattern. It’s a narrow, flat file used for filing inside corners and narrow slots, and its teeth run in a single direction, making it a classic example of a single-cut file.

The other options don’t fit as examples of single-cut. A bastard file describes a coarse grade of cut rather than a specific tooth pattern. A two-cut file implies a double-cut pattern with teeth crossing, not a single row. A rasp uses large, rough teeth and is intended for rapid material removal in wood, not the metal-finishing, single-cut style.
