Thread: Anyone have experience with the Shapton 200,000 grit stone?

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 comparison
http://members.cox.net/~yuzuha/jisgrit1.html and other people have been copying my figures without the color coding. Linde A is alumina stop powder and is 0.3 micron. There is also a Linde B polish that is 0.05 microns (it is used for polishing optics and soft gem stones). 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.
