They are cheap. They don't take up much room, or make a mess. Mine weighs little so it is easy to shove out of the way or move. They are multitaskers. Since my new buffer has taken up residence on the bench it has done chisels, several kinds of knives, and I am about to try it for polishing the sides of a scraper. Had I know how handy it is to put tomato slicing sharpness on a knife I would have bough it years ago just for this task.

Winston uses a drill. Is there anyone on the planet that does not own a cordless drill?
