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.

Made in Japan

Spec:

  • Origin: Osaka, Japan
  • Grit No.: #600 WA
  • Type: Splash & Go
  • Dimension: 210 x 70 x 20mm (8.2 x 2.7 x 0.7")
  • Weight: 794g (28oz)
  • Abrasivewhite aluminium oxide 
  • Cohesive agent: magnesium-bound

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.

poli glow shine
its works great .when applying more coats the shinier it gets i used on several old boats because the florida sun bakes the jell coat right off and no wax made can withstand salty seas , so why not ,, when you apply use the mit and don't gob it on .. nice and easy and recoat in five minutes when you get to about five coats you will be amazed.looks like new .. just a tip also after about a year or so and you want to re apply,, go to your local hardware store and get a gallon of high strength or non diluted floor stripper and put in spray bottle and use to remove old poli-glow also great for cleaning stubborn stains [ i use full strength ] just spray on and brush with a scrub brush and rinse ..and let dry and re apply ,, its also works on car faded bumpers ,, also never use harsh cleaners it will cause streaking the best thing i have found for cleaning the boat after poli glow was put on is car wash from auto store with wax or not it seems not to hurt the shine . it reminds me of mop an glow,,.

Poli Glow used on bottom portion of the picture
Just put it on 21 foot RV, was impressed with the shine. Key is to make sure the applicator is moist. I periodically dampen with water. Realizing it wasn't going to revive the stickers. Question is How long it will last? What will it look like after it rains? Pictures attached, bottom portion was done with poli glow on June 7,2026 and I have just under a half of bottle left. Maybe I will update once it rains or how long the shine last.
