Amakusa medium fine natural stones
The medium fine grit of natural stone!
Amakusa is a medium fine grit stone of natural stone from Amakusa, Kumamoto. There are 3 kinds of sharpening stones which was mined in Amakusa. They are Aka (Torato), Shiro and Johaku (Binsui). Ordinary Binsui is harder and finer grain than Torato.
Good for practical uses sharpness. Good shaping power to produce a precise edge and to make good mud for even blade road polish. It also will produce nice contrast with Jigane and Hagane. Good medium fine stone.
Torato: I prefer harder one. Softer one fits your blade quickly, but you often have to flatten. You may use AI#220 as the flattening stone. Very easy to get good haze even for beginner.
These stones are very reasonable price. Because a big distributor finished their business of selling natural stones. I could get their all old stocks at less than wholesale price of about 30 years ago.
