I would say the batch they have now is like that, I got it from Japanwoodworker for my knives, but its actually a very good stone.

Since getting the above tip, I've contacted Maxim at the address above, and he has been extremely helpful. Asano-stamped Botan, Mejiro, and Tenjyou are on their way and he's making an effort to find a Koma for me. He got a new shipment in yesterday, but these stones are rare and trickle in to him in small amounts, so anyone who is looking might want to contact him sooner rather than later. Not trying to promote anything here, just trying to help out members who have found obtaining these naguras as difficult as I did.
