Hi. I just bought a Naniwa japanese waterstone. On the box it's marked 4,000 grit with stand. When I compare it to a Norton 4000/8000 stone the japanese stone feels much more smooth. Is this an indication that the stone would be more than 8000 grit?? Actualy it feels like 3 time more smooth than the Norton. Could it be a print mistake.:shrug:
The stone is dark sand color on a burgandy stand.
Would this stone be good for the finishinf hone on razors.

Don't rely on the feel. If it is rated a 4K then thats what it is.
It will probably require a slurry stone. I doubt that it will cut as fast as a Norton....but thats not all bad.
Randy with all due respect, on what basis do you hold this opinion on it's cutting rate when you haven't tried it?
Have you tried any naniwa stones?
Am I guessing? Yes I am. It is based on the observations of myself and others that most Japanese waterstones are slower cutting than the Norton 4K. I am not trying to belittle that hone, if it is slower cutting than he will have more control and less of a chance of overhoning. What I don't like is if it requires a slurry stone.
Just my two cents,:)
Hmm, there are many different japanese waterstones, i wouldn't generalise so far myself. Cutting rate between my suehiro 1000 and king 1000 were vast, such that i disposed of the suehiro.
We wouldn't agree if a japanese person came and tried to tell us that all western waterstones were slow or fast or had another characteristic on the basis of trying a couple, would we, because we know there are great differences between different manufacturers products.
I understood that you weren't necessarily trying to say the norton is better than the naniwa, but a new member could certainly take it that way.
I think in general we should be very careful about speculating on products we haven't tried.
If we don't do the best we can and only speak when we are absolutely certain then this newbie and many others would get absolutely no help at all!
We cannot have perfect knowledge but at least we can try to be helpful.
I would go with the mark on the box
calling it a 4k. If I lap my Norton's with
the flattening stone it feels rough, but
if I lap it with a high grit sandpaper
it feels a lot smoother. In the end it
is still a 4k/8k.

Thanks all, I'll keep that in mind and use it as a 4k stone .Quote:

In one word: experience. But grit size isn't the whole story. The shape of the cutting particles does play a role as well when it comes to the final effect.Quote:

Slurries tend to change the shape of the bevel ever so little. If he uses a slurry on the 4k then it would require more time on the finer grits "IF!" they are not used with a slurry.Quote:

They certainly supply a nagura with their 10k super stone, but i don't think it's that common at lower grits. Also the naguras naniwa supply aren't rated that highly by people who have them. If there's not one with it then i would infer naniwa don't think you need one, which isn't to say you couldn't try it with one.Quote:

Jacques, the Naniwa #10000 stone makes a great polishing and finishing stone. It's a slower cutting hone that sharpens at a higher grit. I wouldn't recommend the #8000 stone to finish though. It's not sharp enough to be a finishing hone and there are plenty of better ones available anyway. Nonetheless, it depends on what you're going to use afterwards. If you're going to use green oxide paste or a comparable paste, then I don't think it's a problem. If you're going straight to the linen/leather after the #8000, then you'd have to make extra passes on your strop to compensate for the big jump. I hope that helps. Regards.Quote:

Just my two cents,:)
I've never used the Naniwa #8000 so thank you for the knowledge.Quote:
