Sorry about that. There are little flat cards (that could be glued to something with contact cement for grip), and I think they (DMT) have little stick style hones that are thicker, too.

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.
