I put files to the test to see if back-dragging dulls a file like many claim. I test coarse, medium, and fine files after I built a large testing rig to stroke tens of thousands of times. I also test if back-dragging unclogs files. I use the slow-motion camera to analyze the results and use a microscope to observe all the files!
