What you're trying to do with them is just scuff the soft side of a combination arkansas stone to activate its cutting ability. You can rub hardened steel over the same stone to do the opposite. It doesn't have to be something fantastic, but I'd avoid the square diamond hone thing at harbor freight, etc, as I've had trouble with that one shedding diamonds into a stone.
