Mwa...HAH?

I just want to polish some razors, man!

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.

At one point, though, in 2005, I thought Shapton was going to make a #60,000 grit stone (.25 micron) - it turned out to be the Glass Stones, a little disappointing, but they are nice, too.

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.

the *need* for a post 30k hone is almost zero.
The amount of effort to produce pure nano-grit abrasive particles
increases making the hone somewhat cost ineficient.
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

Awesome box, though - an all-in-one storage container.

Yeah I have one of these hones 5 backhone laps right after the 100k and the razor shaves like a laser.....Honest




What you guys don't believe me?????
