Naniwa Chosera 1000 vs Shapton Kuromaku 1000, the result will surprise you.

Have you ever wondered this:" what is the meaning of the number 1000 on a stone?", "are all the stones with the same number printed on the sufrace perform the same?".
Well, I did a sharpening comparison between two of the most highly regarded stones out there, the Naniwa Chosera 1000 and the Shapton Kuromaku (Professional) 1000, and also threw the Suehiro Cerax 1010, King Deluxe 1000 and even the Chosera 400 into the mix.
I am sure the result will surprise you!

I have been getting more and more into waterstones over the last couple years. Your conclusions relative to the grit numbers are exactly what I'm finding also between different stone manufacturers. I now have about 25 different stones from 5 or 6 different manufacturers (yep, went down the rabbit hole there), and some of the differences are quite large. I'm beginning to understand the meaning of "feel", "feedback", and other factors involving the different stones. In the beginning, they all seemed the same to me, but I've evolved. :-) Mostly what I've found is that I still have a LOT to learn, but it's a fun journey.

[@Iby00]

so if i was to get 3 stones which 3 would i get? arata 400/800/3k or 3k is probably more of an enthusiasm thing and wont really affect daily cooking. so maybe go for 2k or stick to just a 400 and 800 or 400 and 1000?

This is great! I like the actual scientific data rather than KZbinrs keep saying "oh this feels great! Hmm I think it's even better than the other one, even sounds nicer". That doesn't tell me anything. Numbers and pictures with microscope is much better in terms of show the difference. You should collect more data from different grits and brand and make your own chart like the one on wiki. If someone ( yep...someone) happens to buy different brands, they can have a better idea on how they can slowly convert to one brand, like brand A, X grit is actually more equivalent to brand B, Y grit rather than same (x) grit.

Well, if I was doing this test, I would use 4 different marking knives, all the same brand. I would start them on the 400 grit stone, then go to the 1000 grit stones. I would count strokes till the 400 grit scratches were gone. Final test would be to get one of those sharpness testers where you cut through a fiber and it measures the grams of pressure needed to sever the thread. I would also be curious to see how the diamond lapping plates compare. DMT and Atoma. Maybe even the 300/1000 grit stone from Rob Cosman, not the Trend stone because they sold and the replacements were concave rather than dead flat.

[@davidtatro7457]

Fantastic video, and it confirms my own experiences and those of others l talk to, especially concerning the Shapton. I find the Shapton pro line fascinating because they engineered each stone in the series to work well in a progression from the last. The 1000 grit does a fine job of erasing scratches from the 320, but you will really need to go from there to the 1500 or 2000 before getting into serious polishing. I think their 1500 functions more like a typical 1000 grit than their 1000.

[@trappenweisseguy27]

About new stones ; it seems that they often have a ‘skin’ on the outside that performs differently/inferior to the rest of the stone. The 1,000 is a lower intermediate stone for me so I’m using a 1,200 grit stone from a company (not King, but similar) for 25 years now. It’s certainly a lot smaller than it used to be lol. I bought a Bester ceramic 700 grit stone a couple of years ago for taking material off quickly. I don’t really find a need for something coarser. I can always use wet/dry paper on my granite surface plate.

[@gunterbecker8528]

Great information ❤

[@NiclasGudmundsson]

Great video, it's been known for years that the shapton is waaaay muc coarser than any of the known brands actually, but this video points it out.

[@KnivesandStones]

exactly! sometimes for information like this i cant just claim it, so finally sit down and did some 'science' 😁

[@D00MTR33]

There's a chart showing all the different makers an their micron rating. 1K Shapton is about 14 micron while Naniwa 1k is 10 micron(naniwa follows the Jis standard pretty close while shapton has their own rating). There's lots of different standards and a 1k diamond is coarser than a 1k shapton which is coarser than a 1 k naniwa which is coarser than a 1k edge pro or venev stone. That's why I prefer to go of micron rating, 10 micron is 10 micron(sure diamond vs AlOx feels different) and you know about what the finish will be. While a 1000 grit diamond mesh will have coarser finish than 1000 grit diamond waterstone.

[@NickMun]

Thanks for making this video James and the use of the microscopes. The images really answered the questions I had about the edges one gets from sharpening stones. But where would you place the Suehiro Cerax? Is it more like the Naniwa (as opposed to the Shapton that’s likely lower that #1000)?

[@krishnancom]

The Suehiro is probably comparable to the Chosera 800.

[@MrVaeron]

Essentially this means, you either go Naniwa 400 ->Naniwa 1.000 - >any 3K/5K & Strop or you go 400 -> 2000 Shapton and then a 5K Strop. On the other side, the 1K Shapton in Combination with a 3K/5K of any other brand would make a perfect 2 Stone Setup, cause it is still "coarse" enough to take away material in an aceptable amount of time. You would even be able to just live with the Shapton 1.000k

Overall a very well done video, and your evidence is very excellent. I now understand when a guy saids this stone cuts a little faster for the same grit mark classification! The type of stone, who makes it, the actual grit size, how it's manufactured! cost and how frieable it is and what steel is being sharpened? Are there any more variables that need to be understood! It's finally making some sense as I watch the videos, I'm starting to understand all the variables to get an outcome! All I wanted to do was sharpen a chisle! Good job, but you made a statement that the grit had to do with the amount of grit in the stone vs the type or size. I'm not sure that fully correct statement. Over all very good video and I fully understand your closing statement which is fully true I also have found and great conclusion, and data link!

I think the 1000 to 5000 gap is too big. Stick with 2x or 3x progression, so switching from 5000 to 3000 is much better. Maybe 1000, 3000, 8000

Neat comparisons! You didn’t mention it in the sound test, but it seems that the lower grit (bigger particle size) results in a lower pitched sharpening sound. I can’t think why that would be the case - perhaps it’s a fluke - but was an interesting phenomenon.

Hi, I've had a Kai shun pro damascus chef's knife for 15 years. A few years ago, when I first tried to sharpen it, I made the angle too small and I slightly damaged (scratched) the blade. I got a lot of help from your sharpening videos and now I feel comfortable with it (Shapton Pro). However, I'd really like to remove these scratches. I've just tried to remove the scratches by polishing with wool fibre, a very fine polishing pad and a small dremel on some knives of lesser quality and not damask, it worked really well, they're better than new. I'm ready to try it on my Kai but I'm a bit worried about removing the damask. Is there a risk? If so, could I "re-reveal an iron perchloride for example?" Or would you have another idea? In any case, thank you for your videos which have helped me enormously! I'm planning to buy a Kato Santoku SG2 from you, as soon as I feel really ready to maintain a knife of this quality.

if it is only about 1000 grit, the Cerax is softer and slower but does create a slightly better contrast to my eye, however since we need to move to a higher grit stone, I'd choose the Chosera.

[@WormyLeWorm]

If the chosera 400 and shapton 1000 seem so close together in their actual performance, is there a reason to use both? It seems like the shapton 1k could follow up the chosera 400 in place of the chosera 800, based on the chart.

the only real reason to buy both is to actually taste their difference. They are both great stones, but sharpening is a journey that you have to expreience the different to tell.

Having just watched your video and just wanted to point out that while imaging the knife edges after using different wet stones, I just want to say that would an analysis of the surfaces of the wet stones themselves be more useful. This can be done quite easily using an Atomic Force Microscope or Scanning Probe Microscope. Using these tools you can easily map size of grinding particles, their distribution, as well as hardness of the grinding particles and the matrix they are embedded in. If you contact some Physics or Science departments at a couple of universities, they should be able to help you out.

[@carlinlentz6849]

You would be looking at $2000 for an 8 hour day for most scanning electron microscopes (SEM) or electron microprobe (EMP). Kind of costly

[@shaunbulcock7814]

@@carlinlentz6849 While you are correct about the cost of running an SEM or EMP, those are not the family of machines that I am talking about. SEM using secondary electron detector is great for imaging surfaces, but does require a plasma metal sputter coatings to be applied as the specimen is non conducting. Also an EMP is not really suitable as you are not trying to analyze composition distribution, also EMP relies on surfaces being highly polished. AFM & SPM rely on a styles running across the surface and then measuring the deflection of its cantilever using a laser. They don't need the vacuum systems, or level of specimen preparations, that SEM & EMP require. They just require the specimen to be small and light weight, about 1cm x 1cm in size should be fine as the weight would not strain the piezoelectric mount for the specimen. For these reasons the costs of running one are usually a lot less. And yes, for those to do recognize the name, I did work in microscopy at Sydney University for about 15 years

What I see on the Shapton pictures that I don't see on the others is several scratches that are much deeper than the rest of the scratches on the blade. They are especially evident in the higher magnifications. That tells me that the grit in the Shapton isn't nearly as uniform as it is in the other whetstones and that the larger individual grits are making the deeper scratches. The results in this video match the results under equally high magnification in a different video regarding sharpening a straight razor with another Shapton whetstone with much, much finer grit, either 15,000 or 16,000 as I recall. That in turn suggests that the entire Shapton line has this fault.

Thanks for making this video... very interesting, I have 3 of those 4 stones ( missing the babies) and though I've never done a side by side comparison the way you did....I had exactly the same impressions you did...the microscope photos definitely confirmed it. Only place I have a different opinion is after a shapton 1k I find you can definitely skip up to 3k+...you just have to spend a bit longer on that stone. I can understand where you're coming from though. I imagine at the store you want to have constantly repeatable results when sharpening and sticking to a specific stone brand progression definitely helps streamline the process. I personally, and it could be a bit of a downfall for me I know, jump around throughout my stone collection. I try out different combinations almost every time I sharpen. The end results are always very good and often very different in terms of end results. Personally, I find that interesting, and I sometimes do that as well for some of the knives I sharpen for others...(most others, who I know won't notice or appreciate it,I keep it to a more or less same 3 stone progression)...but for those 2 or 3 whom I know will get into the minutiae of it...it can be a lot of fun Take care

At K&S, we often do 1K to 8K jump, so I do agree that you can jump from Shapton 1K to a 3K stone. As long as the higher grit stone is fast enough, you can do the jump and leaving a toothy but refined finish.
