Nakayama Kiita Koppa Lv 3,5 (a220)

I have seen one time before stone like that, it was also Nakayama.

feels very soft but very very fine. Make green mud/slurry.

And feels super nice ! On everything knives razors and tools  

Very light yellow color, what they call in Japan lime yellow. Most sought after Nakayamas out there ! 

Quite big and thick koppa.

But still much cheaper then same full size Nakayama Kiita, that will go for 5, 6 times more . 

Collector Grade !
