I just received two norton two sided water stones I ordered, the 280-1000 grit, for restorations when I get to that point and the 4000-8000 for regular honing. I have also ordered a Naniwa 12000 grit super stone for finishing. I also received the norton flatening stone.

Are there any other grit types I should plan on getting or are these sufficient and are these good non natural stones?

Any thoughts would be greatly appreciated
