Thread: "Shapton Glass" In Search of the Perfect Edge

Thanks for clearing that up! I don't know where I got the idea that it was a diamond stone.

Something I picked up on these stones, yes they do need to be lapped, not nearly as often as other stones....
Once they settle in they should very rarely need lapping, from what I understand they swell slightly after the first few times they are used, then you lap, then years go by before you might lap again....
I plan on the exact setup you have there to replace my Norton's 1k/4k/8k then I guess sooner or later I am going to have to try the 30k although I can't see how it can be twice as good as the 16 k

One question??? after the 30k do you find any use for a pasted strop??? maybe a .25 ???

Thanks for the info....

The 30K isn't twice as good but I have the fever of trying to get the perfect edge. I like to use 20 strokes on the Chromium Oxide after the 30K. It gets the edge even smoother. I am not sure if the .25 diamond paste would improve the edge or not. I don't think it would hurt it. We could use the .25 diamond paste or wait until the 60K Shapton came out.

Well, BJ, you've convinced me to get the Shapton 30K. I know it's probably overkill, but I've got HAD, so there ya go. It will round out what I have so far:......


That would only leave the 6K for me. We may have to start a Shapton brotherhood!

I haven't had the time to really put most of these stones through the paces, but I've used the 16K quite a bit and all I have to say is:.....The Shapton 16K Ceramic on Glass Stone ROCKS! I have yet to overhone on it (as you mentioned, BJ, it sticks to the stone (in a good way) when it seems like the edge is ready. I've asked both Dr. Moss and Lynn and neither of them has said that they've overhoned on the Shapton 16K.

Great stone to work with. I'd say probably my favorite right now.

I've got a fair sized corral of stones both natural and manufactured. To date, the only stone that was amazingly flat right out of the box oddly enough (since it's a natural stone) was a Tam O' Shanter from Coully. The pencil grid disappeared across the entire surface of that stone in less than 5 passes on the Shapton GDLP! I thought I was seeing things and didn't believe it. The re-grid for good measure proved I wasn't crazy.

So, in my experience, virtually any stone needs lapping prior to use including the Shapton Ceramic on Glass stones.

BJ, I thought the same thing when I bought the Shaptons, but then while traveling for work yesterday I stopped off at an antique store and couldn't resist a vintage Thuringian sweet polishing stone in a wooden box. It has the same type of paper label the Eschers do, but it's not an Escher. Same color and absolutely silky smooth and soft. Can't wait to lap it and play. HAD is not cured for me!!! Oh, and I may be buying a rare red coticule or two as well, but I have to see pics first. Dang HAD I tell ya!
