Thread: Has anyone tried the glass stones made by Chocera

I have been after some info on some Chocera made glass stones that Bob Kramer has his name on. Has anybody used them. I don't want to buy them if they are only a much slimmer version of their full sized stones. Thanks.

i found some j.a. henckels kramer glass stones. is that what you are referring to?



they don't look like the same color as the shapton glass stones (haven't heard of chocera or naninwa chosera glass) .. but i doubt that means much…

Honestly your reference to them the other day was the first I ever heard of them at all, let alone them being used on Razors,, I question the word Ceramic in conjuction with the Chosera if Chocera is even the same, and if both made by Naniwa..

Being as the other Zwilling set of stones is made by Naniwa and are actually just a different color Super Stone the chances are high that these might be Choseras.

BUT

I would really nail them down on the Ceramic term before I bought them for razor use, haven't seen many positive reviews when it comes to Ceramics and SR's with out the use of a slurry Paste or Powder also on the stones...

I hope that answers your questions

Yes, that's the ones I am referring to.

There is a video on YouTube, with, Bob Kramer, where he is saying that he got them made specifically by Chocera. I have never used Naniwa stones of any kind, but to me the stones looked pretty hard. He may have had these made to give a somewhat toothy finish to an edge for knife usage, otherwise why do it, when there is already a great product already made. Maybe he just wanted a unique stone with his name on it, I don't know.

I am a bit dubious about getting good data off someone who has a vested interest in a product though, that's why I asked here.

To gssixgun.

Sorry, I don't really get what you mean when you say Ceramics not having good reviews, aren't the Chocera stones you just bought, Ceramics?

I think I will just forget about these stones until I hear a few reviews.

I have a few Shapton Pro's, so I think I will just fill out the gaps in that line with Shaptons.

Thanks for your answers.

I know nothing about the stones in question, but some bits of information.

Chosera (Chocera) is the first three characters from the product name 超セラミックス砥石. Cho 超 means "super" or "ultra" depending on your marketing tastes, and seramikku is pretty obviously ceramic.

The product is a single product line made by the company Naniwa. Saying a stone was made by Chosera is akin to saying an Apple product was made by iPad.

I'm guessing that the "famous" guy who had the stones special made was doing so in case of any cracking or crazing mentioned in another thread on these, and other stones. In googling that cracking/crazing business I found stuff on knife forums. Some of the guys glued their choseras onto glass, wood, whatever. So as a stop gap and maybe a marketing gizmo the kitchen knife guy has brought out a line of these for sale to those who don't do it themselves. Just IMHO ....... BTW, the shapton pro line is a good one for razors IME. If you already have those they ain't too shabby at all.

There's probably not enough info on them in the razor community yet. I know several people who use the Shapton GS series stones including me, and really like them. Lynn has a video on youtube as well. I know Max out in Vegas uses them. I like the ceramics, they're fast. When you get up to the 16k level, the edge may feel a bit harsh on your face. Sometimes a few laps on crox will take care of this.

As far as regular Chosera go, they're great stones, magnesia bonded, as opposed to resin bonded. This is supposed to give them greater speed when honing. Most guys that hone on a regular basis, use the Chosera 1k as their main bevel setter. I wouldn't mind having a full set of Chosera's. I only have the 1k, and I'm happy with it. I don't like the jump from 5k to 10k with Chosera, and the 10k is about $270.00

If your thinking about them, I'd wait a bit for some feedback from the community.

Spyderco for one makes Ceramic sharpening Hones....

There is no need for Water or Oil nor is there any breakdown of any Binder and Grit into slurry...
Waterstones work one way to cut steel Ceramic Hones work another..

Ceramic Hones have a very good reputation in the Knife community because they mesh well with some of the Super Steels... (Google Ceramic vs Japanese Waterstone it will give you some great info over at Bladeforums)

If the Hones in question are simply Naniwa Chosera cut in half and mounted then they are most certainly a viable option.. I myself have not found the trick to getting the 10K Chosera to work as a smooth finisher, I heard they can be coaxed , but honestly I didn't buy them for that reason..

The Japanese name Chosera is an abbreviation of "Super Ceramic". That's the reason the OP referred to them as ceramic, I think.
