Round waterstone

Dieter Schmid used to sell them as well as few other vendors - I haven't seen any for sale in a while.
 
Looking on the web, there seems to be a European-based online vendor called 'KnivesandTools' (.com) indicating they have them in stock (1000, 3000 grit, with a 320 stone showing some availability delay). 220 mm (8.66 inch) diameter. All the pricing on their site is shown in Euros. No idea whether they ship overseas, but you might look them up. I found the listing in searching 'Naniwa Chosera round stone' on Google.

Thank you that is exactly what I was looking for and they do ship to the us so thanks very much
 
As far as I know they have been discontinued, I would make sure the vendor has them in stock before making a purchase.
 
Why have they at the very least stopped making these? I would think that many people would love them.
 
I'd love a set of them. Currently I'm using the inside face of the wheel that came with my Triton wet grinder for my big stone work.

I had to cut a HD bucket down to soak it in as it doesn't hold its water well. Being a blend of diamond and AlumOx - looks just like a dark India stone - this thing does a great job of resetting bevels without making deep scratches. My other stones feel small now...

That's awesome. I was actually starting to consider looking at the tormek japanese waterstone wheel laid on its side.

Where'd you hear that it has diamond in it? I'd think they'd be touting that on their website and I'm not seeing anything of the sort?

High-grade diamond grindstone sharpens steel edges superbly.

and from Rockler:

Large diamond-impregnated stone works with the integral water bath to hone your tools to amazing sharpness, with no loss of temper.

Disclaimer: I've had mine for a couple years, at the time I bought it the replacement wheels were over $200, now they are closer to $100 - still not cheap. Individual wheels may or may not be made with the diamond formulation, or the drop in price might be from increased availability/production, read the fine print...

Edit to add:
The unit itself is maybe a step up from some of the other budget wet wheels, but after using it a bunch I'm not sure I'd recommend it anymore unless one is into truing hardware. It work well enough on knives but is somewhat slow. Works well enough on woodworking tools but is tough to index reliably. There's a reason the Tormek costs so much.

The Triton stone is really nice though.
 
I am looking at getting a tormek actually. My only hesitation is the fact that I would want to get every jig and wheel for it lol. The whole kit cost a little over $2000 if you get the black wheel and the waterstone wheel with all the jigs
 
That's why I went with the Triton. I didn't want to spend the $ on the Tormek and then have to buy another wheel for tougher steels. I picked up a bunch of jigs for the Triton and it all came in under $450.

I simply couldn't afford the Tormek. I have since picked up the bench grinder adapter for Tormek that also works with the Triton jigs, the difference in tolerances is glaring. But, the Triton does what it needs to do as long as I am paying attention. I don't use it enough to justify the cost of an upgrade.
 
I've written Triton to see if they can shed any light on the wheel composition. It'd be odd for the wheel to be so inexpensive, even at $200, for it to have much (if any) diamond in it, and I'd expect their own site to be rather loud about it if it did since it'd be a unique offering. Most wheels of that size are just aluminum oxide, including the Tormeks.

As far as using wheels on their side as a manual stone, I have a small worn out wheel for my Grizzly wet grinder that I sometimes use similarly.

There are a few alternatives that might be cheaper.... the smaller "T-4" model is for the "home user"... can't get the SB (black) wheel, but save almost $300 on the Japanese wheel, plus the machine itself is cheaper (although you don't get all the accessories that come with the larger machine). All the jigs fit it. (There's also a "T-4 Bushcraft Edition" right now, that has the knife jig, ax jig, and even a Mora knife included... for under $20 above the normal cost).

If you want the large machine, sharpeningmadeeasy has a "wheel substitution" option (only place I've seen it), where you can replace the regular grindstone with the SB version for a small fee... but saves you well over $100 (probably don't need both wheels anyway). They also have packages with the various jig bundled together.

And of course there's used (which I initially got)... the machines are pretty durable, so even a used one is usually in pretty good shape... just make sure it has some decent stone left, or is priced accordingly.
 
Interesting--Triton says that from their technical records, the wheels are silicon carbide. Never seen brown silicon carbide wheels...I think their info is wrong and they're brown aluminum oxide, but at least they were able to confirm that they don't contain diamond.

Who did you speak to that provided that info?

Keep in mind they are based out of Australia, all the text describe a diamond blend. Not sure I'd trust a single response from a US outlet. They do make a smaller version that uses AlumOx - is listed on the label. I've attempted to contact their HQ about other accessories but never got a response.

20 seconds in, this video is put out by the co.
 
Thanks for the video link, as I couldn't find anything from the company themselves making the claim. I submitted the inquiry direct through the website but received a response from their US branch. I've asked them if they could ask someone at HQ about it and included a link to the video. Quite the mystery!
 
Well, here's what I've got, a pic of the box, the label on the stone, and the stone itself (part DW for diamond wheel) - which sparkles very much like a diamond plate tho not with the same density. I'd guesstimate about 10% diamond with the rest AlumOX but is hard to say just looking at it. There's definitely something in the mix that has different reflective/refractive properties that is not silica left over from vitrification. There are some blue bits that look like they might be left over donor material.

Pic of the surface was taken right up near the label where it has never been used to grind, so the shineys are not glazing from steel. If there is no diamond they are begging for a lawsuit.

Based on how it cuts I'm very confident it is indeed a diamond blend though. In fact I am very surprised many waterstone manufacturers and other benchstone makers are not releasing stones with relatively small amounts of diamond added - the whole thing doesn't need to be diamond to cut high VC steel. This would keep the cost down and the stone wouldn't be overkill for lower RC steels.

The ones made for sharpening carbide jointer blades seem to have a reasonably high diamond content and are pretty inexpensive - $35 for a stone about the size of a King 4k. With a binder more conducive to hand work these would be a huge value - they load up too fast to be good for anything more than light finish work.

In my work on my diamond/SiC blend honing compound, I found relatively small amounts of diamond made a huge difference - 5-10% by weight is plenty, with amounts as low as 3% being the threshold for seeing a difference. In fact over 15% and there was no real improvement in performance when used as a stropping compound on high VC steels, and performance appeared to decline on carbon and low RC stainless at that percentage compared to SIC or AlumOx.

Diamond being less dense than SIC (esp the industrial grade), relatively low percentages by weight wind up being a respectable amount by volume.

Yeah--that's why I'm curious. I believe that the addition of small quantities of super-abrasive (diamond or CBN) to bonded abrasives has the potential to improve performance and yet the only bonded stones out there I usually see with diamond are those Venev ones, which are very thin because they're made with straight diamond.
