Shoubudani is mine super close to Nakayama and produced similar stones as Nakayama usually super fine and hard
Sometimes in Japan shoubudani stones have been sold as Nakayamas
Perfect for knives and tools
This one is crazy fine makes super nice Simi mirror contrast finish
But still very easy to use and makes black swarf very fast , can also be used with Nagura
Super beautiful red and orange colours
Make perfect kasumi finish very easily !
