In your first thread, either set will do just fine and are all you will ever need… until you start chasing the extra 2 percent some of us chase.

I prefer the Norton in the middle stones over the Naniwa super stones as they don’t load up as much.

The bevel setter does not matter.

And the 12K super stone is bullet proof, all you will ever need to finish.

But really a 4/8K Norton is all you need to hone and will keep you shaving forever. The 4k can bevel set and the 8K can finish, all but probably 10 percent of us are capable of maxing the 8k performance from that stone. It is a testament of the stone, it is just that versatile of a stone with a very, very wide range.

I have well over 100 stones of all types, I use the 4/8k Norton to hone 95 percent of all razors almost daily.

You are on the right track and splitting hairs, trying them once will probably just confuse you more, but won’t matter, all the stones you listed are great stone, the differences are just nuances of how they feel, performance is the same.

Do go to a meet you, will learn a lot hands on, and will gain light years of insight. It really is the little details or tricks that make a big difference… anyone can rub a blade on a stone…
