A friend just gave me a King S-3 Sharpening Stone (made in Japan). It is old but in good shape. I have just flattened it on 400 wet paper and it is very nice and smooth. It looks a bit soft.

Can you tell me, compared to a Norton 4000/8000 where it stands in the process of sharpening a razor or is it even adequate to sharpen razors.
