Hello, everyone.

I've been experimenting with my new Nakayama Asagi (Thanks, Aaron!) and collecting a few extra nagura stones.

I've read several times that you can use EITHER the Tenjyou OR the Mejiro stone between the Botan and Koma/Tomo stages, and that using BOTH is unnecessary. Can this statement be fairly compared to the idea that you can use EITHER the Naniwa 3K OR the Naniwa 5K between the Naniwa 1K and the Naniwa 8K stages, and that using BOTH is unnecessary? (From my own experience with Naniwa Super Stones, I find that the 1K > 3K > 8K progression is more than sufficient for a great shaving edge.) Or is there more to it then that? (All things being equal, that is. I'm aware that not all Tenjyou are the same, and that some Tenjyou may be even finer than some Mejiro.)

While my main question is about the interchangeability of Tenjyou and Mejiro nagura, please feel free to comment on the interchangeability of Mejiro and Koma too.

Thanks in advance.

Regards,
Chris
