I am obviously a newbie. I have searched for hours for info on a couple stones I have. I do not know if they are usable to me or not...
My first stone is Grey in color, measures 12" X 3" X 1". It is marked on the end "A600LVG2". It appears to have very little use.
The second is a Norton Hard Arkansas Stone Jewelers Stone HB 26. The stone appears to be used only a couple times, if that.
