Hi,
Interesting youtube video on file dragging here (21 minutes):

I'll keep on filing the same as I always have. And yeah, most of the
time I'm a light dragger ;-)

Fireball Tool
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!
