Adam, I've sharpened rasps and files in white vinegar. My initial impression was that it works, but that the new sharp teeth don't hold up very long. I experienced chipping of the teeth after one or two uses (probably 2 hours worth of work) in walnut and cherry. So, it does work for short time but it is not a long term substitute for a professional sharpening or new files.
Your endgrain is like your bellybutton. Yes, I know you have it. No, I don't want to see it.
