The "7" is on sale up here north of the border, but unfortunately (or in my case fortunately!) not the full-size one.

You're doomed--

I ordered the 30K grit stone 7. The price was low enough that I thought “What the heck.”

The ‘7’ stands for 7mm, so the abrasive is thicker than the regular bench size line (5mm).

I beg to differ. The 0.44u that I bought works great on razors.

I had the 0.44 and unfortunately it was defective - it shed large particles. I returned it to the vendor, Mark at CKTG who returned it to Ishida San at Shapton. When asked about the replacement, Ishida San said that the 0.44 was not recommended for razors and I didn’t need it because I had the 0.85. Apparently, although the average grit size is 0.44, it has some larger grit in it than the 0.85.

This is apparently why some of the HR and HC series Glass stones are not recommended for razors. That chart from Jende showing this has been posted recently.

Having said all that, people are using Glass Stones that aren't recommended for razors with good results, including me, but what Mark told me was enlightening.

Ask him and see what he says.

Thanks. That's good info. I got lucky (for once) since mine does not shed. I use it the same as I did the 16K glass stone, no more than 10 laps after a translucent arkie. Polishes the edge and does take the keen-ness up a notch. I believe that I had heard the 16K was another one that was not recommended for razors but many straight razor users loved them.

Seems odd that they would use 'average' for their particle size rather than some sort of sieve apparatus. Maybe that's just too small of a particle to sort.

Apparently you can’t use a sieve for grit that’s anywhere close to fine enough for razors.

There is also a question of how makers ‘report’ their grit sizes, some use the average grit size and and others use the coarsest grit size. And maybe the grit is non-linear, IOW there’s more coarse grit than fine or visa versa. There’s a document in the SRP Shave Library about this, scroll down to the last few paragraphs, though it’s all interesting reading.

The 16k HR Glass Stone isn’t recommended for razors according to the Jende chart which allegedly came from Shapton. I need to ask Mark about which ones of the G7 series are recommended for razors, that info seems to be missing.
