Thread: PSA, Shapton Glass 1k

Hey buddy - that tray looks very familiar!

I am debating on getting a grunt work stone. Either a Chosera 600 or a shapton Glass 500. Which is superior?

Thanks,
Mike

Depends on how you define grunt work ie how bad the edge is. When I did a lot of restores I used the Shapton Kuromaku 320 grit. By comparison the GS 500 is "gentle" & slow.

I have them all, Shapton Pro 320, Shapton double thick 500, and Chosera 600.

In the 320 range, I’ve been using a mellow 325 DMT. Then either 600 Chosera or 500 Shapton HR, not a huge amount of difference in the performance of these two, they’re both good. The Shapton Glass 500 is cleaner, no blue mud like the 600C, and swarf is a lot easier to see on white vs dark blue. Get the double thick if you go that way, about 50% more $ for 2x as much stone.

I haven’t really compared the 320 Shapton Pro to the 325 DMT, but the stone is consistent while the diamond plate mellows with use over time.

Is the glass 500 a hard stone? I was also curious if it release huge amount of slurry. I read that some courser stones release lots of grit and can micro chip edges. What is a HR glass stone?

The Shapton Glass 500 doesn’t slurry much if any on its own. All these are top tier stones, none have any issues with razors. The 600 Chosera slurries a little as does its green sibling the 1k (so I’m told, a forum member calls it ‘ol’ sloppy).

I think I may go ahead and take the plunge! I need to see if they are any Christmas sells going on now. DO I get he or hc? What is the difference?

Here’s a couple of links that talk about the Shapton stones.

If you have Shapton Pros, there’s no real advantage to the Glass HR series except speed, and the ability to cut hard or wear resistant steel. The HR series was designed to cut wear resistant semi-stainless Lie Nielson A2 plane steel. They’re great with the modern powder steel kitchen knives. It’s nice to step up a notch in fineness with these, for example using a 2k instead of a 1k. I use the 4k HR a lot for light bevel work on full hollow razors, the speed is an asset when you can’t push very hard.

The Shapton Glass HC is designed for laminated carbon steels. They’re slower and polish more than the HR series. There isn’t a whole series of these available at least in the west. If you’re a fan of 8k razor finishers, the 8k HC is your stone.

Nice breakdown in those links on the shaps. Reinforces my experience with them, ie the Pros keep their shape better & cut fast but the trade off is that they cut deep. Not as harsh as diamonds but I've always said they're the next closest thing.
