The right size tubing squeezes / flattens to conform to the shape of the file and slips on and off easily.
I have a set (13) of very expensive hard-to-find miniature filing machine files (they cut on the pull - or downstroke - in the machine) and are very sharp. I use lengths of plastic drinking straws for those as they are small in size, something like needle files. I use them in my clock repair shop, saving me hours of laborious hand filing!
