My new stone

I got hold of a very rare Atagoyama Kiita for my self usually Atagoyama is softer stones like Hakka
But this one is very very fine and medium hardness very even in structure because it is not suita it is very smooth on the knifes and razors, incredible fast too.
I am very proud to add this stone to my collection :)
size is 210 mm 85mm 67mm
Fines Lv 4,5
Hardness Lv 3,5

I cud not resist to make a video :)  There is a peak too how i flatten my stones !
