Naniwa 12_000 for razor
I found the Naniwa 12_000 to noticeably improve a razor's edge. It has served as a finishing stone before moving to a CrOx hanging linen strop. Alternatively, it has served as the last synthetic before moving to a natural stone. I'm jumping from an 8k Rockstar to the Naniwa. It seems to be a reasonable leap with no issues thus far. However, since it is a soft stone, I tend to a lap it a fair bit before/during/after use.
Glad I made the decision to pickup the Naniwa 12_000, i. e. The Honda Civic of finishing stones for razors. For this stone, Knifewear provided very competitive pricing. Furthermore, their staff were very helpful.
