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 near perfect Karasu Ozuku #30 is near perfect in shape, without cracks, and has a beautiful grey pattern. This stone will provide a great mirror polish.
