I started out with a set of Naniwa SS.
I initially bought the 2-5-8-12K stones.
I was a bit afraid the 1K would be a bit to risky for me. I didn't wanna ruin anything.
I found lots of info, spent many hours reading about how to use these stones, and eventually I learned to keep my razors good, and even hone my new acquisitions.
I like these stones a lot. They don't see much use anymore, but that has nothing to do with their abilities as hones. They are great!!
