I bought this stone at Home Depot a few years ago. It has two sides, a reddish brown side and a yellowish brown side. The sides are separated by a black plastic separator. It only says "Made in Japan". The original box had the grits listed but I have lost them. I do remember it was in the thousands. The yellowish side feels smoother. HD apparently doesnt sell them anymore so I can't find it there.
Thanks,
Dave
