Bernard Zhang 5th July 2020, 06:36 PM Hi Guys,
My shapton 8000 Grit stone seems to have some metal swarf or shavings embedded into it.
Blades tend to skip/skate over this stone. Or cut very slowly with it.
They are shapton glass stones.
In the photo. They are freshly flattened and I've just put the back of a chisel on the stones to compare the the differences between the stone.
Each time i flatten the 8000 grit stone, it still looks grey
I have the 1000/3000/8000/16000 glass stones. I dont do anything different to each of the stones and I dont have any issues with the other stones.
I am trying to get in contact with the Shapton folks in Japan. But their 'contact' section on their website does not work. There is not a shapton representative in Aus and I can't find one in Usa.
If anyone knows what up, could you let me know. Or have come across something like this before.
thanks in advance.
Regards,
Bernard
Tech Data:
I use hone-rite in the water mixture.
I sharpen Lie Nielsen A2, PMV11, O1 and Vintage metal with these stones
I flatten them with the 300 grit side of my trend diamond stone.
I've checked with a straight edge that the stones are all flat to 0.0015".

markharrison 5th July 2020, 08:37 PM I bought my Shapton stones from Lie-Nielsen Australia. Don't know if they still sell them.
I have this exact stone and don't have the issues you are having. I flatten my stones with a DMT flattening plate. I just use plain old water sprayed on with a garden mister. I'd never even heard of Honerite until just now.
Maybe try doing a little more flattening and taking off more than you usually would?
I don't know that this was very informative, but...
justonething 5th July 2020, 08:37 PM I think you could use a Nagura stone to rub against your water stones (with water of course) to form a slurry to clear the small iron filings from the surface of your stones. There should be plenty of videos showing you how to do it.

Bernard Zhang 5th July 2020, 08:46 PM Hey Mark
Thanks for your comment.
Hone-rite is just used for rust prevention. Nothing too special about it.
I think I've flattened the stones like 10 times thru general use and the 8000g still looks grey
I'll try flatten it like a few more time, when I'm in the shed next
thank you
Bernard
Bernard Zhang 5th July 2020, 08:55 PM Hey Justonething,
Thanks for your message
I am not too sure about a Nagura stone. The shapton website states that the glass stones don't need a nagura stone.
I also do not think a Nagura stone would be too effective in my case. Because the stone still looks grey after i have flattened it with a 300g diamond stone.
Regards,
Bernard

Dakotapix 5th July 2020, 11:36 PM I’m still new with Shapton Glass stones but I learned about a gadget called “Sabitoru Rust Eraser” on a knife forum. I bought the Medium from Amazon and it seems to work very well for cleaning steel particles from the stone. If you search around Burrfection.com you might be able to find a video that describes the use of this product. He also sells the Rust Eraser but you might be better off dealing with Amazon.
Edit: Here’s a link to a Q & A to Burrfection.com in which Ryky, the owner, answers questions from his subscribers. Along the way he does mention the Rust Erasers. While the product’s name is what its design was for, it is in the ability to clean sharpening stones that he likes It.

Fluddman 6th July 2020, 09:21 AM How old are the stones. Is it possible you have cut through the thin top layer of glass stone?
Simplicity 6th July 2020, 12:19 PM Try these guys,
They may be able to answer your questions.

This works on my Shapton Glass stones but so did an Atoma 400 diamond plate. Use running water when cleaning the stone.
Bernard Zhang 6th July 2020, 06:19 PM Hey Fluddman,
They're 3 weeks old.

Hey Matt,
That is where I got my stones from and he told me to ask on forums + contact Shapton Japan.

Bugger. That does sound a bit odd. Watching with interest as I am planning to upgrade to a set of Shaptons soon. Hope you find a solution soon.

Hi Bernard.
They said , go back to the supplier an ask them,
Despite them being a distributor, that’s very odd?
Cheers Matt.
justonething 6th July 2020, 09:39 PM Bernard, Does the discolouring affect the performance of the stone? My Tormek Japanese water stone changed from the pristine light blue when new to a now greyish blue. As long as it works, all I do is to remove as many embedded steel particles as I can and just live with it.
markharrison 6th July 2020, 10:11 PM My 8000 Shapton glass stone is not grey...
Mind you mine is a lot older than three weeks.
Bernard Zhang 7th July 2020, 12:15 PM Hey Fluddman,
Yeah little weird. Other than that, I would still highly recommend the Shapton glass stones.
Sharpening is so fast and so fun!
Cheers,
Bernard
Bernard Zhang 7th July 2020, 12:18 PM Noted, I will try and do some more research!
Bernard Zhang 7th July 2020, 12:19 PM Hey Justonething,
I feel like it does. And I feel that the 16000 stone cuts faster and more than the 8000 stone. Which in theory should not make sense.
Cheers,
Bernard
Bernard Zhang 7th July 2020, 12:21 PM Hey Matt,
Yeah no idea. I'll give them a friendly call soon haha
Regards,
Bernard
Bernard Zhang 7th July 2020, 08:55 PM MYSTERY SOLVED
The stone set that I got includes :
1000 HR, 3000 HR, 8000 HC
The 16000 glass stone is also a HR series stone. I've attached the difference between HR and HC below.
All makes sense now! I will buy the 8000grit HR stone and piff the current one I have.
Thank you so much guys!!!
Shapton Glass Stones HR vs HCThere are two different series of the Shapton Glass Stones. There’s the HC series and the HR series. The HC series is a bit softer than the HR. Because of this the HR series is better suited for harder steel types and powder steels. Obviously, the HR series sharpens a bit more aggressive than the HC series. Shapton indicates that the HC-stone can be used for carbon steel blades, but our experience is the HR series will do fine as well.

Where do you get your Honerite?
Fluddman 9th July 2020, 06:23 PM And where did you buy your glass stones? Beard and Blade?
Was just looking at the Shapton lapping stone - only $489 (I was tempted until I saw the price).
Thanks Bernard
Bernard Zhang 9th July 2020, 07:29 PM Hey Justonething
From these blokes
woodworksupplies.com.au (https://www.woodworksupplies.com.au/)
Last i spoke to them, they had 10 bottles left and I picked up two because they dont know when the next shipment is coming in
Bernard Zhang 9th July 2020, 07:33 PM Hey Fluddman,
Yep i got my stones from beard and blade. They've got a 10% off with new account, so I just use a new email each purchase.
I just use my trend diamond stone to flatten. I have not have a problem with that. All my stuff is too new to view noticeable wear.
I think the main difference between a shapton lapping stone and a normal diamond stone, is that the shaptons will last longer. But i am not sure how much longer given the 2x price tag.
With my basic googling, beard and blade seems to be the cheapest, with their 10% off too. (unless anyone can point me to somewhere cheaper)
Let me know if you get the lapping stone. Keen to hear how they go!!
Regards,
Bernard
