Thread: New hone Naniwa Diamond Whetstone #3000 grit

How does the flatness appear? Very interested if you can go straight to using it without running some steel to "dull" the high spots....

Good point. The stone comes with a #400 conditioning stone. I wet the surface down and let water pool on it. I then gave the conditioning stone a good run over the entirety of it's surface. Now, you can see the colour of this stone, and the conditioning stone did abrade some of the surface, causing a slight colouration in what could very loosely be called a 'slurry'.
I used this stone last night, and it does not feel anything like a diamond lapping plate as far as feedback goes. In fact it doesn't feel like a superstone 3k either. It feels quite fine and seems to be on the high side of 3k. I tested it against the superstone with and without slurry, and the slurried superstone was far more abrasive than this hone. To be honest I need more time on this hone to work out where it sits in my progression, if anywhere. I haven't used it like an Atoma, for lapping/dressing, and I doubt it would take a a lot of material off a jnat, so fine it is. Jury is still out on this one. I am going to dress the surface of my Wakasa with it, and just look at how fine it makes its surface appear. If it were really reflective or shiny, then it may be a surface you could use at the death, ie dress it with this stone and do half a dozen super light laps to end with.

PS, it's very flat, perfectly flat.
