I did not want to hijack the other thread: http://straightrazorpalace.com/hones...-one-hone.html

I think I have decided on a Norton 4/8k stone. So here are my questions.

Will I see a big difference by adding in a 12k later or just never worry about it?

Is it ok to use the stones that you sharpen your razors with to sharpen other knives/tool?

Thanks for the help.
