Phil, that has to be one of the best summaries I've read. Well done, sir! (I removed the content as I hate long quote posts)

Phil thank you so much for all of your hard work! There is so much here it is hard to take it all in and digest it all. I will however follow your lead and buy the choseras. I spoke with Bob at Oldawans again today and he is going to make up some customs stones for me. We decided on 1k/2k and a 3k/5k stones. I'm not a well to do sort of guy? But I am going to get the ball joint arms as well.
Hopefully this will hold me over for a little while? Thank you again!

I am sure you will be happy with the items that you ordered, and you will get great results. Please keep us posted on your progress.

Just my 2 cents to add to this (interesting!) topic.

My favorite progression for a mirror finish is 1200 ceramics - 1600 ceramics - 5K Chosera - 10K Chosera.

I started doing this after Tom's suggestion for a "horizontal move" on the grit progression chart - as you can see the 1600 ceramics have about the same grit size as the 5K Chosera's. It works perfectly!

As far as I know, the 1200 - 1600 grit ceramics are currently not available, but the currently available ceramic stones have similar (not the same) grit ratings.

Does anyone know the "grit rating" on the micro fine ceramics?

Mark, looking at a set of choseras. Currently have the micro fine ceramics, and was thinking I would progress from them to a set of 2k/3k choseras. Now you throw the 5k/10k and say that works well. Looking at one set for now and want the most bang for my buck progression wise.

5k/10k Choseras are going to give you a much higher degree of reflectivity than you'll get from the micro fines. I finish most of my working knives with the micro fines and they leave (visually) a light haze with distinct scratch marks under a loop. I don't think they work quite as low as their 1.4μ/.6m rating, but they leave a nice clean edge for most things.

I think you'll be happy going from the micro fines to 2k/3k Choseras, JMO. Then you can add the 5k/10k if you want it even more refined at some point.

Phil made an accurate remark on ceramic stones and grit rating. That said, I find the 1200/1600 stones fit in quite well according to their grit rating.

As to the microfine ceramics, I think the general opinion is that the coarse ones may be a little more coarse than the 1200 and the fine ones a little finer than the 1600 stones. But I find it hard to tell.

I think you can safely go from the microfine ceramics to the 5K Chosera's. But you can always first buy the 5K/10K Chosera's and if you're not satified, add more.

Hey, on a semi-related note, what kind of wear are you all seeing on the Chosera stones?

The best bang for your buck progression would be the 2K/3K stones.
They will give you most of the mirror for 30% less in cost...and make it much easier to remove the lower grit...including the ceramics...of any grit, scratches.

How is an answer to this possible.. really. What do you mean?

Without going back and looking for reciepts and knife sharpening logs.. I can't hardly give you an opinion, let alone a definitve answer.

I would guess that I have had my Chosera stones for over 1.5 years... BUT some came sooner than others..
I am jealous of those that order all of them at one time. I think it took me about 8 months. I started with the 400/600 and the 800/1K... was thrilled, but never happy knowing that there is MO -Bettah stuff out there (Mo-bettah is relative...think of an anal retentive guy that has to have 0.025 micron on nanocloth strops...Then figures out that it is pretty much useless for everday sharpening).
The last ones that I got were the most expensive ones.. the 5K/10K

:(

I have been using up to the 1000 grit diamonds for as long as I have had them. This takes a bunch of the work form the 400/600 Choseras... as well as the 800/1000. I could give a knife count, but I would be lying...I just don't know. It has been a bunch... but I have used the different stones a significantly different number of times over that undefined number of knives anyway.

Synopsis: The 400/600, after flattening three times are about 85% of the original thickness. The 800/1000 maybe 85/80...I use the 1K lots more. the 2K/3K one flattening, close to 90% the 5K/10K ...well damn, I kind of screwed up the 10K...and it hurt my feelings badly. I had some chipping, so I fixed them... too much diamond plate. I would say 85+% on th 5K... maybe 75% on the 10K..mostly from over agressive maintenance..
Now..what does that tell you...?? I didn't take actual measurements..just eyeball.. no actual numbers..;)
I think that , given proper use, and maintenance, the choseras should be around for several hundreds of sharpenings.. several.

Some of this also doesn't go with the conventional wisdom that the coarser grit will wear faster... this is given equivalent use...which I haven't done with mine.


I am sure it was not what you were looking for... But then, I am not even sure of that. A vague question can get no more than a vague answer.. sorry
:evil:

Why do you ask? Do you have what you consider to be excessive wear. better than expected longevity???
How are yours doing?
