Thread: what grit?

ok, i'm new
i have nothing here except a strop and one side is pasted. by the time i get a single stone to maintain an edge for minor repair the cost might dictate that i go ahead and get a combo stone. probably a 4000/8000 norton? my questions is: will 8000 grit be fine enough or should i get a kit, say from lynn, that features 3 (japanese?) stones in 5/8/12k? thanks ps. is it possible to get away with one stone? say a 12k? or would that not be course enough?
