Thread: Read this if you own a SHAPTON!

Maybe cutting with a laser? Can you score tempered glass and snap it?

It would be nice to have narrow shapton ceramic stones. It's a bummer that I feel I can't use them for screwed up blades that need a narrow hone. Just last night I started honing a new TI Super Gnome that surprise, needed a narrow hone (2nd Super Gnome that won't respond to a wide hone). I set a passable bevel on the 1&2k Shaptons and went for the edge of a Tam and very narrow Coticule with hundreds of passes on each. The edge is still not where I want it.

So.....narrow Shaptons? I'd like them. Even if only for coarse grits to finish on narrow natural stones.

Here's an alternate idea for you, Alex:

The 1K is about $43 + shipping. If you spring for the cost and your idea works and....you think you'd be fine with offering to sell ripped Shaptons, I think it would work in your favor. I could see myself buying a ripped 1K Shapton for let's say $40 shipped and I bet some others would as well.

I was considering calling Howard to see if he could get me a Shapton Pro and cut it to 1" for me. As apparently the pros are getting discontinued, and the glass stones can't be cut, I'd have to get a pro stone soon in order to have any chance of owning a narrow shapton.
I also don't hold out much hope of this project bearing fruit, as apparently once the outer layer of tempered glass is penetrated, the glass will shatter. That said, I would be willing to donate $10 to buy a suitable hone to experiment on, as you seem to have plenty of ideas. I just gave up when I heard it couldn't be done!
I REALLY hope this works.

I have never seen a shapton IRL, but can you seperate the glass and the abrasive without ruining it?
If so, good! Then you might have a shot at it.

No... it's already annealed after the heating process to harden it, it doesn't work the other way.

Good luck.

If you try to score tempered glass it will explode into little pieces. Save your money.

I could sell a 5mm+ thick 1000pro, you could slice it a adhere to the substrate of choice. Or better yet will trade for 1000sglass or 1000 sigma

This is perhaps a silly question -- but I have no experience with warped blades. Why not use a ceramic sharpening rod, for freshening knives? I have one that's rated around 10k, but you can get them at different grits.

Personally, I want a wider Shapton. Could I glue a couple together?





I guess some of us are just never satisfied with what we think is merely minimal.

I disagree here:

"Finally, it should be noted that the effects of the tempering or the heat strengthening process can be reversed by re-annealing (stress relieving) the glass. "


Anyway, I just hope Howard says that Harrelson said that Shapton will be making them narrower! Before I try anything though, I'd call Shapton and ask for details about the specific glass used and how the ceramic is held to it in hopes of finding how to un-do it.

I have tried something similar in the past in an attempt to force some razors so warped they may as well have been pigtails into submission (Ok, only a slight exaggeration). I used PSA honing film in various grits adhered to wood dowels. It solves the problem of honing the entire blade from heel to toe beautifully since only one line is making contact with the bevels and spine (the narrowest hone in the world). However, it seemed to me that Randy Tuttle's theory on the process held true: For ultra thin edges like full and extra hollow razors, the force applied to the edge is magnified. I could not hone a razor to shaving sharp that way.

It would be cool to see someone make it work.

I am just thinking of this because I personally want a narrow 1k that doesn't need to soak like a Norton (did I mention that?). If nothing pans out I may have to try a DMT 4"x7/8" or 6"x2" in 1200 grit.
