The backing looks to be glued on and the joint is too straight.
I'd say it is not a combination stone.

It's definitely not a natural combination stone, but didn't the old coticules have the BBW glued as the backing instead of the slate they use now? I have a coticule with a BBW backing, but it's definitely glued like in the pictures above.

Yes. I have one myself.

That is correct. Ardennes Coticules started backing to natural slate tiles, because it is more cost-effective. In the old days, when labor hours weren't that big of an issue, it was cheaper to back with something that was very common and plenty: The blue schist that was mined together with the Coticule. It was only later discovered that the blue schist also has honing abilities. In the old literature about Coticules, I have found nothing so far about the Blue for honing purposes.

If sanding, soap and water do not completely clean it then use some oven cleaner on it. Works great on stones that have old oil, grease, dirt etc.

Would oven cleaner work well for other types of natural stones? i.e. thuringian stones?

Never had the need to try it myself but when Kees posted that he had gotten oil on an Escher by accident Howard stepped up and said he had used oven cleaner successfully on some of his.

sbrouwers , nice stone. Please post pix when he is cleaned up.

Ok I scrubbed the hell out of it with soap and water (a little cleaner but not much). I then went on to the oven cleaner, not much luck. I did lap it with sand paper from 320 to 1500 grit through 2 drawn grids it is now flat.

I do not think the back is a blue I ran a pocket knife over it a few times and it damn sure didn't feel like any sharpening was going on, unlike the other side. I posted a full pick of it as well. So I guess my final question is would anyone take a razor to it?

Oh around what year did they start using slate on the back?
