A rasp is a sort of a file. It generally has sort of projections which rip away at stuff: like hoofs, metal pipe, wood. Just about anything to get ready for being made smooth by something a person wants something to be smooth, when it is rough or uneven, or just too much to deal with using a file. A file more or less goes for smoothing, not roughing up before smoothing. It is much finer than a rasp.. One can think of a rasp as a really rough file. Also, a rasp is the sound that the singer who sang "Maggie Mae" has in his voice all the time. Short story: he was in a hospital for a while because he was diagnosed as having a raspy voice. Lots of people including me asked the question, "How do you tell its raspy?" One gets a raspy voice when his throat is scratchy. It seems you are talking about a very rough file.
