I agree. A file works perfectly. The same file I use to coarse sharpen my ax or hatchet works perfectly for shovels. It only takes a minute or so to clean up the edge of the shovel blade. Most people go overboard and put too much of a fine edge on the shovel blade then wonder why the blade chips or the edge folds over or burred easily.
