Naniwa Diamond waterstone hybrid?

[DeadboxHero]

Where can I find more information on these.

How do they compare to Shapton Glass, Chosera, etc.

Do they load up? Glaze?Dish? Tear out? Cutting speed?longevity?

$130 a pop is pretty spendy.

Interesting! I have a diamond oil jointing stone that HeavyHanded introduced to me but have not used it much, it was quite a fine grit - it worked very well though but I could not tell you anymore what "best practice" was. HeavyHanded may be able to chime in here, certainly he has used them more intensively. I have not heard about those Naniwa diamond waterstones though.

The Naniwa Diamond waterstone is not any faster than a regular waterstone, the difference comes in its ability to cut high alloy metals. They are very dense and very slow wearing but there is not much advantage in having them unless you simply don't like the feel of a diamond plate. I have used the 1000 grit and personally, I didn't like it all that much... much happier with my Shaptons, or in the Naniwa line the Chosera/Pro stones.

They look pretty cool, but I cannot imagine needing them at the low to medium grit range. At the polishing level on HSS and high Vanadium steels they'd probably be very nice to have.

Let me know how they work

I do have a diamond jointering stone that works pretty well, believe it is about 3 micron abrasive. Abrasive density is somewhat low and it loads up quickly, but it does do a great job.

Even at bulk prices diamonds are pricey compared to SiC or AlOx, so I'd expect those stone to not have the highest concentration of abrasives to binder.

Yeah, sounds cool right?

Haha dude, your like the Zknives of Sharpening stones.

I need a Jason B quick reference guide!

Is there any advantage for high volume sharpening? Less dishing?

It also looks like it only has 1mm of abrasives.

What's it made out of? Magnesia bonded diamond matrix?

Does it load up?

Hey Martin, you got a link or pic of that diamond stone?

228mm x 60mm x 17mm - 1200 - 600 grit / DARK BROWN
Part # JS-0701 - NCD 1200/600 Diamond Stone - For CARBIDE ONLY.

I initially used it with oil, but found it worked great with water after a nice long boil with a dishwasher slug.

Not sure where the rating numbers come from either, I broke some of it down and the abrasive particles looked to be right around 3 micron. It loads up rapidly and does not grind very quickly, works best for cosmetic polishing with a bunch of mud, or as more of a hard strop block.

It can make a very bright finish - have to dig mine out and try it again. Most recently I've been working dust off of one edge with a carbide saw blade and using it for a diamond stropping compound (block on the left).

Haha, I have used a few stones for sure.

I think they are a great idea on paper but in use I don't see much advantage to them. They might stay flat for a long time but they are also very difficult to lap. I do not know how they are made.
