A burr file starts out as a regular flat file. It is placed flat on a stone then run back & forth to remove the sharp edges that would normally cut metal. The result is a file that will only catch small burrs that are on the surface of your work. To answer dlane's request for a photo, these things look exactly like a regular file. You'd have to know what it was, or figure it out when you notice it is a pretty crappy file
Never heard of a file being used this way. Draw filing, yes, stones to remove burrs, yes, but nothing like this. So, if you grind the teeth off then I assume the idea is that the sharp edges of the flats you create do the cutting instead of the original crests of the teeth, correct? Hunh, learn something new every day.
