Naniwa P-306 Professional Stone #600
Pickup currently unavailable
The Naniwa P-306 Professional (Chosera) #600 Stone is aggressive enough to do fine repairs but fine enough to transit to a 2K/3K stone.
Ryky decided to test the Naniwa Pro #600 because of how much he enjoyed the Naniwa Pro #800, which is still his favorite non-soaking sharpening whetstone. The #600 is a different beast than the #800 - it is more aggressive and faster cutting than other #500-700 grit whetstone he has tested.
Being such an aggressive whetstone, it can also serve as a fine repair whetstone for minor chips. Ryky did find that going directly from this whetstone to 6K takes longer to clean up the edge, so if this a whetstone you end up getting, consider a 2K or 3K whetstone.
Due to the wear speed, Ryky does not recommend this whetstone as a daily sharpener, and should be reserved for very dull knives, or knives with very minor chips on the cutting edge.

How to use:
This is a non-soaking whetstone, but can absorb a lot of water on the surface during the first use, so 1-2 minute soak will aid when first using the whetstone. Afterwards, simply apply water on the surface when ready to use. Rinse and wipe dry with a hand towel when done, and allow air dry at room temp. Do not leave in water.
How to clean:
If the stone’s performance is slowing down, or seems to be diminishing, you can clean using a rust eraser, nagura stone, dressing stone, or a flattening plate. Be sure to clean the entire surface of the whetstone when using any of these methods to ensure even wear of the whetstone’s surface.
Great rough stone, Its fairly aggressive while allowing your knife to smoothly glide across the surface.
