Hi, all! Haven't asked any questions in a while, so I'll let loose with a few of them. :D
My Pike barber's hone has rough spots on, as though it has been etched by an acidic substance (does mold cause this?). Has anyone tried to sand a hone in this condition? If so, what grits should I use? Is there a better way to repair the hone? Is it even worth bothering?
