What did you get?

They’re sold out already on the two that I wanted. They sure didn’t last very long.

That means that there will be more, I hope.

If you want more control with these, I would recommend gluing them back to back on a custom built paddle. For travel, I've done this with the 1" x 6" version, minus the glass backing as offered from CKTG, and it works quite well choking up on the paddle grip with the forefinger and middle finger extended underneath the stones for support.

Wait. I think I moved the decimal point.

30K!

A 30k glass Shapton for $110? You can’t beat that if you don’t mind honing on a narrow stone. Honing on narrow and smaller stones opens up so many more possibilities as many want the bench stone size and prices reflect that. Reminds me of a 4/8” razor.

I bought the .44. The next one down in line was already sold out so I bought some more .25 diamond paste to get the order up to $60 to get the free shipping

Well, I ordered the 0.44 also - reviews are mixed on the 30k, but I was never curious enough to spend big bucks for a full size 30k to find out for myself how it hones. So I guess in a few days I might know!

Same here. I would never spend that kind of money on a razor hone.

30K + sounds like splitting atoms to me but I will try it for $55

There are multiple scales and methods for measuring grit sizes.

Shapton sells their 30K stones advertising a 0.44-0.49 micron level.

Suehiro sells their 20K stones as 0.5 micron. Suehiro, along with Naniwa, Norton, and King stones follow the JIS system which dates back to to 1998, at least according to what I have found.


Thus, a Shapton glass 30K and a Suihiro 20K are similar in grit.
A Shapton glass 16K and a Naniwa 12K are similar in grit.

Of course, it is improper to assign a grit rating to natural stones, but it is commonly done anyway. With so many different grit rating scales, even if you call a Chinese Guangxi hone a 12K, who knows which grit scale it being compared to.

So you’re saying that we can’t even assign a grit rating to synthetics? (<- /H)
