Thread: New Ozuku-yama Karasu from Morihei

I decided to enjoy a recent windfall and get a high-end finishing j-nat. I gave Michiko at Morihei some guidance about price and he sent me some options.

His top pick and the one I went for was this Ozuku-yama Karasu
(大突山合砥カラス). Dimensions are 205×73×27mm 1,080g



He has suggested using the stone with a Mejiro nagura and water (no tomonagura).

His other recommendations were (all comments from Morihei):

#89 Narutaki-yama (鳴滝山)
Approx. 207×75×25mm 1,000g
Hard
Very good quality
Most of Narutaki stones are yellow or light blue color.
But this stone is red brown color. So, this one is rare.



#107 Kitsu-yama (木津山)
Approx. 205×78×34mm 1,400g
Little Hard
Very good quality.



#32 Nakayama (中山)
Approx. 210×73×35(mm)1,270g
This stone is one of the hardest among Nakayama.
This stone will grind steel well and put a fine edge.



I will report back when I have received the stone.
