I know this is a dumb question but..

Is a Barber's hone just a very fine hone like a Naniwa 10,000 or 12,000 grit?

I ask because when I google Barber's Hones to look for one, I only get back antiques like the Franz Swaty or something similar. I know they are generally made of ceramic, but that's about all I know.

I went to a barber shop supply site, and they have hard Arkansas stones for barbers, but I'm not sure that's the same thing.
