Ban Nagura ( バン名倉) (~2500)

I purchased a few Ban Nagura to test where they would fit in a polishing progression.
By feel alone, they are easily my coarsest Mikawa Nagura and I give them around a
2500 grit rating because they feel in between my Binsui and Aizu or Kaisei. I'll most
probably only use them for eliminating remnant scratches after using the Binsui that
are a bit troublesome for Aizu or Kaisei to remove as to avoid going back to Binsui
again.
