Greetings.

I, too, have recently come into one of these C-Mon barber hones. Mine does have the two grits, one side is something of a dark rusty red (best way I can describe it), while the other is grey/black.

Is it a safe presumption that the black grit is finer than the brown? I'm guessing it's similar to the colors of sandpaper, the darker it is, the finer the grit.

Also, when I received it (from my barber), I was told an oil would be needed when using it to sharpen. This makes sense, however is there one type of oil that folks prefer over another for this type of application?

Appreciate the time.
