I was wondering what stones do you guys find cut the fastest,I have some knives with M390 steel and ZDP-189 and I find that my Chosera's for the KME will work not bad but my Shapton's do cut a bit faster.

I was thinking of trying Nubatama's but not sure if they are any better.
 
With those steels, Diamonds will be the fastest. Shapton Glass will be your next fastest on hard steels and your Chosera stones I wouldn't even use on such steels. In my experience Chosera stones work best on average carbon and stainless cutlery, no PM steels.
 
With those steels nubatama won't do much, you need diamond plates or ceramic stones. Some Shapton Pro stones work well, Shapton Glass will work, and Suehiro Rika/Cerax surprised me but they worked well. These were the stones that cut CPM 3V and Elmax the best for me. Another option is Sigma Power stones since some have been formulated to cut PM steels. However there isn't much info online about them I've used a few but ultimately sold most of them. My pick would be diamond plate for coarse work and Shapton glass for the rest of the progression. Maybe throw in a strop loaded with diamond paste just for a little extra sharpness.
 
I just did a spydie in ZDP189. I used 140 then 400 diamond plates for putting the edge on and one micron diamond paste on a strop to polish it up.
 
I find for Elmax and S35VN the Chosera stones work alright but it's the other steels that are a real pain with them,I'll look into the Sigma Power stones and I'll see how they work for me,I also have diamond hone for my KME and I find the Gold Series for the KME last longer then the DMT stuff for sure.

Thanks for the help guys.

kme has a 50 grit diamond stone called the beast.

its by far the fastest stone I have ever used to remove material especially on those higher end super steel.

I prefer the venev bonded diamond stones for refining the edge as I really like the scratch pattern and the end results. i got them from gritomatic a vendor on this forum. they also have boat loads of other kme stones.

I'd love to try Shapton Glass stones at some point.

Might give the American Mutt a look as well. :)

this is also a great and affordable stone for removing material if you do freehand.

That sounds like a really good, durable toothy edge in some of the steels I have. Not familiar with ZDP189, how does it hold up?

+1, the Atoma 140 cuts like a belt sander...even on my ZDP-189 blades.

I like it toothy on that particular blade, it's a dragonfly. It's very very stubborn! Once you get a good edge on it though it stays for a long time.

Shapton vs chosera on pm steels, is it the feedback or the finished results that you like better?

Curious because all I use is choseras, I've tried Shapton glass, I must say the 2000 mesh glass stone is definitely a Sharpening stone but that leaves alot of precision, yet the 2000 grit Naniwa is definitely more of a finishing stone in disguise, not as much bite to the edge and much more difficult to crisp up a rounded Apex on the 2000 chosera

I know for me I use the KME system and I could care less about feedback and only the end result plus the faster the stone cut's the better.

I'm thinking I'm going to get a set of the Diamond Bonded and Silicon Carbide stones for the KME use them for doing all the hard work then use my Chosera's and Shapton stones and my really fine Suehiro stones,I find with the Chosera's they just take to long on a lot of harder steels and Shapton's do cut faster but not that much in my opinion but I could be wrong.

I also find that if I do not soak my Chosera stones for 5 minutes they do not hold water very well and your splashing water on them all the time and I have heard of people having them glaze and not do anything at all until you lap them on a fine diamond plate.

The Chosera stones simply lack cutting power due to abrasive type. IMO, they are only slightly better than King stones on high wear PM steels.
 
DMT diafolds are the most convenient and inexpensive for me the extra fine or extra extra fine will take care of any super steel
 
I find that KME stones are better than DMT. I think he used to use DMT as the diamond stone that he sent to you with his sharpener. His stones are better. A word of caution, If you use his 50 grit do not try to get a burr with it because it will rip the edge to pieces. One the profile looks good move on to the next stone which is 100. You can get to your apex with that. You also need to be careful with the diamond dust it will scratch your blade badly. When you want to remove the dust spray Windex on it till it's clean and then wipe it down. This is a word of caution when you use any diamond stones and just be patient. All the super steels are a pain to sharpen. Sometimes when I really don't feel like dealing with it you can send it back to the manufacturer And they do it for free, you just have to pay for shipping. Hopefully you have another knife to carry If not maybe it's time to get a second EDC knife.

I agree with you 100% emjay4248 about the KME Gold Series Diamond hones being better then the DMT,the Gold Series outlast the DMT by around 2 or 3 to 1 if not more providing you do not push really hard when using them.

The KME Gold Series and Atoma Diamond Plates are more then just leap's and bounds better then the DMT's,the KME Gold Series and Atoma Plates seem to use a much better electroplating process to hold the Diamonds onto.

I don't know about the KME stones but the Atoma plates I have experience with. I also have lots of experience with DMT and I'm not sure how you are wearing out stones. I have had my set of DMT Diasharps for almost 10 years and they are still going strong.

The Atoma plates are very good, no denying that, but I do not find their longevity to be that good. I'm on my second Atoma 140 in about a years time and its already worn to the same cutting speed as my decade old DMT XXC... which has been used for sharpening and stone flattening in a professional setting.

Not saying you can't wear out a diamond plate but if you are wearing them out sharpening your own knives then you are doing it wrong.
 
DMT are the stones I use for EVERY steel I have. I have not met a knife that I could not sharpen to a razor-like finish with my DMT stones. I don't see how anyone can wear out a DMT stone either. They may get finer in grit over years of sharpening, but never worn out for me. I have a set of DMT stones close to 20 years old now and I still use them daily for touch ups.

Ok, but the Gold series stones are only offered in 1"X4" size. Double this size and I would be interested. Of course then the price would be doubled as well. DM
