Thread: ID for this one please?

It's two grades of arkansas rock. the dark one is medium and the white one is fine. they're sold commercially now, pre-glued. As in, this last decade for sure.

use dishwashing liquid and water for lube, and forget the oil. it's smarter, cleaner, and wears both stones and knives less. what you have is suitable for pocket knives and small kitchen knives, but sub-optimal. What it will do better than other rocks is garden tools and machetes and such, things you'ld not waste a better stone on. Might use it for a broadaxe..

I probably own 50+ Arkansas rocks, a dozen bench hones, some Lily Whites, burnishing stones in translucent and surgical white and black.. I'm somewhat over-informed for no very good reason, and might be wrong but don't bet the rent on it.
