I have seen charts listing this stone. Where can I buy one?
if it exists (which I doubt, but there is a 20.000 grit shapton)
you can probably get it from Tom Blodgett at jendeindustries.
A 200.000 (200,000?) grit Shapton?
I never saw one.
The highest grit of shapton (of all synth. hones I know)
is 30.000 in the Mesh System (wich is 0.5µm) from Shapton,
availiable in Glass and Pro.
Both have been reviewed and talked about in this forum, I think
Ah, I know what he is referring to:
this grit comparson sheet:
http://straightrazorpalace.com/advan...son-sheet.html
lists indeed shapton 60, 120, 200k
BUT I think those are fictional for comparson sake
If there is a 200,000 be prepared to go to the bank and ask for a barbers loan lol.:)
There is no such thing. I just calculated the yellow figures for comparisonQuote:

You also see people selling diamond powder up to 100,000 or 200,000 mesh and the micron sizes on those doesn't quite match up with Shapton's version of JIS grits either.
Anyway, you can buy the purple, green and pink stones but the yellow numbers do not exist and are just there for comparison.
where can you get the lowest grit diamond or whatever else powder?
there are several high-tech polishing compounds.
The question is, do you really want to go there?
Those compounds have been invented to polish parabol mirrors
for astronomic telescopes.
An example would be Baikalox,
an aluminiumoxide compound with uniform grit size around 50nm,
that would be 0.05µm
But I can assure you with standart 0.5µm diamond or chromium oxide,
you can get perfectly fine results.
If not, nano-powder will not help
I got some .25 micron diamond spray from www.deltaonelapidary.com
I also got a small amount of .25 micron diamond dust from a company in Australia. I've lost the invoice so you will have to search for it. Both are marked 100,000 grit. I hope that's fine enough for you.....
It has certainly done wonders for my meat cleavers, hatchets, axes and adzes not to mention my hari-kari knives ( used only once )!!!!
.5 micron is plenty fine enough. Save your money. I didn't.

I think it has been said before that some of the grain size grading systems lack the ability to rate anything smaller than #10,000 grit is what determined the 100,000 grit status.Quote:

What about making my own 200,000 grit waterstone? I can get 0.1 micron diamond powder, mix it into a soft clay base, and heat-harden it in the oven. Anyone ever tried?
If you find success, put me on the list!:) It might be a little pricey, though...
Now there is an interesting thought, but then you run into the problem of the particles of binder being larger than the particles of abrasive.
I did try something like that once though.... I took a thick copper sheet and glued it to a walnut base, lapped the surface and scraped with a machinist's scraper, then rubbed in a mix of slow set epoxy and .25 micron diamond dust, tapped it to get the bubbles out and level the surface and let it harden. At first it was rather rough and knives tended to bind on the epoxy (I was pretty sparing with the diamond content), but it eventually smoothed out and seemed to act like a polishing cloth (this was before I had any fine grit waterstones so it didn't make a whole lot of difference to the edge coming from a fine DMT plate, but it did polish. Gave it to a friend's father about 20 years ago so don't have it to experiment with anymore.
I wouldn't be surprised if R&D at Shapton, Naniwa and maybe even Norton might have took a stab at it. :shrug:Quote:

That´s why a synthetic post 30k hone is highly unlikely.
I have been making efforts to make my own hone as well.
What I did was mixing abrasive particles with resin,
that comes with an extra hardening liquid.
You just mix the three compounds and stirr...
It didn´t work for me. The mix of abrasive, hardener and resin wasn´t right.
This takes a lot of effort and try and error, wich we can usually not afford.
If you want a super high hone, just go for a Nakayama natural hone
or experiment with pastes. Some apply superhigh pastes to a hone,
like the Chinese.
Or just, as we always did, make a strop :)
200,000? 200,000? Where would it live? It can't be for real. What are you trying to do here?

You *also* left out the #3,000 grit stone:(Quote:

What you guys don't believe me?????
Muhahahahahaha
Naniwa already makes diamond waterstones (as in, diamond particles in clay binder much like a traditional Japanese waterstone) but they only go up to 6000 grit and are rather expensive:Quote:

yuzuha, that's some great info! I want to try something like that, I imagine one would use 1/3 part or less of epoxy or it would be sticky.
