Recently Imanishi-San has started selling these Ozuku stones. Slurry will develop but a nagura stone is recommended to aid in creating some slurry. This stone is great for razors and tools. These stones are mined in Kyoto Japan. Natural whetstones wear much slower then synthetic stones. This stone will last years if not tens of years.
This Type 30 Nashiji Ozuku is a great stone, wonderful nashiji pattern, with almost enough yellow and green to be called Kita, with any minimal inclusions. It will cut fast. A Nagura will help but slurry can be made with out especially when sharpening anything single bevel.
