Naniwa P-310 Professional (Chosera) #1000 Stone has been one of the standards by which many other #1000 grit whetstones are compared. It is highly refined, and gives your knives a very clean edge. This whetstone is pleasurable to sharpen on, and feedback is immediate. The wear speed is just right, and does not load up very easily. Ryky considers it a fairly hard whetstone, but not as hard as a ceramic based whetstone.
Comparing it to Ryky's favorite Naniwa Pro 800:
The 800 is faster, more aggressive, and gives more immediate feedback. Those who are looking for absolute speed will enjoy the 800 more than this #1000.
This #1000 stone is more refined, slightly more forgiving, and easier to use and learn on, especially for beginners. Those who want to enjoy the sharpening process more, will likely prefer this #1000 over the 800.
