Review: this is maintenace for sharpening stone. - This product is intended for the maintenance of sharpening stones, so it may not be necessary for everyone. However, if you have purchased a Japanese whetstone, we highly recommend getting this as well. It is used to keep the surface of the whetstone flat and properly maintained.
Review: Easy to use for flattening water stones - I have used a full sheet of 120 or 220 grit waterproof silicone carbide sandpaper on a piece of 12”x12” 1/2 inch plexiglass to flatten my water stones for 40+ years. Over all those years I’ve probably spent 50 times the cost of this Naniwa stone on silicone carbide sand paper. The sandpaper method works OK but it’s annoying for a bunch of reasons so I finally broke down and bought this Naniwa flattening stone. The Naniwa is faster than my old method, easier to use and store and the Naniwa leaves a nice finish on all my stones. The Atoma 140 diamond plate is the best tool for flattening but it’s expensive. My only “con” is that I wish it was about 25 % larger. Naniwa makes a bigger flattening stone but it’s about $70. If I need a stone that big, I’ll revert to my full sheet of silicone carbide sand paper and plexiglas. Attached is a photo of the Naniwa stone (black) next to my tan 50 year old King 6000 grit water stone. Hope that helps!

## Questions & Answers

**Q: My Japanese is a bit rusty; What does the instruction in the back say to sprinkle something?**
A: I rub the flattening stone against the sharpening stone using running water.

**Q: Can you use the flat side to sharpen/flattening single bevel knives? would be useful to have this as a dual function stone**
A: I wouldn’t use this stone to sharpen.

The flat side can be used for major repairs and possibly for thinning but will negatively impact the life of the flattening stone more so than if you just used it for flattening.

**Q: How does this flattening stone compare to the Norton flattening stone?**
A: Being that I haven't used the Norton flattening stone I can't give an honest opinion. The Naniwa stone has worked fine for me for leveling my stones.

**Q: will this fix a king 1000 and king 6000 watering stones**
A: Unfortunately my stone arrived broke.

### ⭐⭐⭐⭐⭐ Works Great!
*by A***L on May 11, 2025*

Leveled out my 5+ year old synthetic stone with this in a matter of minutes. Suddenly, my knives keep their edge about 4x longer than before! I'm a professional line cook, so those knives and that stone see a lot of action. I was also able to use the rough backside of this stone to put an edge on a hopelessly dull old pocket knife!
