Can someone tell me what the standard Nagura that ships with say a Shuobudani Type 100 from JNS? There is a box to click if you want to add Nagura. I assumed this is a very fine finishing stone beyond Meijiro but less than Koma. Is this correct? I am getting the exact same edge on all my razors, and there is another level I am not hitting. I never get HHT off of the stone. I have to strop first. I realize that HHT is not the end all, but it is a gauge I use to see where the edge is. My edge is great WTG, but ATG needs work. Ultimately I want to get a 4 piece Asano Nagura from Botan to Koma but, if the tan Nagura I have is less than Meijiro then I will start with Meijiro. My progression has been Naniwa 3/8 then Coticule from mud to light slurry, then Shuobudani mud finishing on light slurry.

Thanks in advance for your guidance.
