Like a saw, the file should always cut on the return stroke.

• A. Yes
• B. No
• C. Sometimes
• D. It depends

Answer: (B)

In hand filing, the cutting action happens when you push the file forward into the work; the teeth bite and shear metal on that forward stroke. On the return stroke, you lift or lightly guide the file so it doesn’t cut, keeping the surface smooth and preserving the teeth. So the idea that a file should always cut on the return stroke isn’t correct. Focus on applying steady pressure during the forward stroke and easing off on the back stroke to avoid gouging and dulling the teeth.
