The hardness of Oozuku stones varies a lot. Some are of medium hardness (3 of 5), some are semi-hard, some are very hard...
The structure and friability of grain of Nakaya stones usually are better for achieving finest edge of the razor.

The best of Oozuku stones are Oozuku from KARASU strata, not from Tomae (Awasedo type, like on photo above).
