It won't.

I've seen people try to sharpen dog tags back to high school. None of them worked worth beans. What edge it would take, on the ones I've seen at least, were more of a scraper/butter knife level. Some people claim to have gotten better, but I want to know how well the edge held up to even the normal usage.
