Intersting concept flossing your saws teeth. I've never seen a need for it. The teeth on any saw I've ever run were clean and shiny for the most part. Maybe a little dirt or dust here and there but nothing the file couldn't handle. After every tooth I wipe the file across my pants leg to knock off the filings. That's why my Carhart Arctic bibs have a fuzzy appearance on the right leg and my old pair has a hole wore in them.
