Looking for diamond/ceramic bench stones for that won't become obsolete too quickly.

I've used the brown (medium) Spyderco bench stone to touch up edge imperfections on a Maxamet folder I purchased from a friend here on the forums a year or two back. Certainly wouldn't try to do any serious sharpening or reprofiling, but it is remarkably versatile for those occasions where I don't opt for diamond (plated or bonded)...or, occasionally, a water stone.

I have way more hones than I need...but I've grown attached to them all and find I (seem to) enjoy owning them as much as the knives they service.
 
I recommend Atoma Diamond Plates over DMT. I prefer the feedback from the Atoma, it's more consistent, absolutely flat, and they scream at you if you're holding the angle wrong.

For bench stones/plates DMT has their DuoSharp and DiaSharp.

DuoSharp are the plasticky polka dot pattern. DiaSharp use the same abrasive but give a continuous metal surface. Both get the job done, I prefer a continuous surface.

I have a DiaSharp 600. After purchasing an Atoma 600, and comparing them, I also got the Atoma 400 and 1200.

Atoma does not offer a higher grit, so I also got the DMT Extra Extra Fine.

If Atoma were to make a higher grit, I would buy it immediately, if the price was reasonable.

Going higher in price, there are various Bonded Diamond stones on the market. My problem with these is that they're using a formaldehyde based resin. I make a point to not purchase formaldehyde products when possible. I will say that some people prefer these above everything.

Beyond that, I also got a Spyderco Ultra Fine and modified it. I made it absolutely flat and converted it to a dual stone. I ran a progression on each side and finished one more coarse than the other.

I have a lot of diamond strops and highly recommend these.

I also have a small Shapton Glass progression and simply use my Atoma plates to lap my Shapton stones.

Thanks for the input on the Atoma 140 vs DMT XC and XXC plates. It looks like I can get the DMT XC for around $55 and the Atoma for $80. Not too much of a difference if I am going to keep these for years. Do you feel that extra $25 is worth the cost of admission?

as far as the diamond loss on DMT plates goes, I actually noticed that on the DMT Diafold I picked up when I first opened it. It was mainly on the corners where the plastic case rubs when closing it, and it’s just a field sharpener so it didn't bother me that much. I supposed it would be a bigger annoyance if it was on a plate I used often. Would you suggest the Ultra Sharp plates over the DMT interrupted plates? If so, I noticed the Ultra Sharp plates are available in several grit combinations. Which would you suggest? I was thinking maybe the 300/1200?

I really like the idea of giving lapping films a try over a strop. Once I get a good glaze going on a strop, sometimes it seems like nothing gets it back to normal no matter how much I clean it.

So... I actually just picked up a Spyderco 8" x 2" Ultra Fine, lol (it was for sale here on the forums for a good price). Can you think of a place for it within the stones I have, and plates I plan to get, or should I probably just be passing it along? Maybe after the Arkansas Translucent for maintaining an already sharp edge? I was pretty impressed with the finish the Fine side of the DoubleStuff and DoubleStuff 2 left on soft stainless steel (ie tru-sharp and sandvik 12c27) and the fine and ultrafine SharpMaker rods seem to do well on most my knives.

The Spyderco Ultrafine is a classic and has a place in every sharpener's arsenal. As popularized by YouTuber Michael Christy it is a great finisher for diamond plate progressions. The Spyderco UF gave me my first hair whittling edges, and I still use it to help pop off a burr a good amount of the time. There is something to be said for an ultra hard ultra flat stones ability to align and refine your final edge.

Is this for environmental reasons? An allergy? In any case D Diemaker does not use phenolic in the Diamond Matrix stones; his resin might be formaldehyde free?
 

I was looking at those Venev plates in particular, but after reading up on them it sounds like maybe they are still working out some of the kinks with the bond, feedback, and whatnot?

To me, yes, the Atoma 140 is worth the extra $. I have the Ultrasharp 300/1200 and both sides have held up very well. In fact it was somewhat used and gifted to me from another forum member, so at first I thought of it as a "backup" plate. But now its the first one I grab - have a done hours of work with both sides and with a bit of Barkeepers Friend it it is still "like new".

A DMT Coarse/EF duosharp would be a strong contender but cost a lot more.

Ceramics will work great on a lot of steels, but for high carbide or even very high Rockwell I'm not a fan. I don't think I'd sell it though. On a lot of steels they work great.

It looks like that Atoma 140 is going to be the winner for reprofiling. It's name keeps popping up and it looks to have absolutely glowing reviews.

As far as the Ultra Sharp goes... It looks like I have two options for 300/1200 grit plates. I can either go with a dual sided plate, or two separate plates. The two separate plates are only about $8 more. Any advantages to the separate plates other than less chance of abrasive pullout? Also... It looks like my local, mom and pop outdoors shop (one of the best in the state!) has the DMT Coarse/Extra-Fine Duo Sharp interrupted plates and the Ultra Sharp plates for basically the same price. With the price being equal, would either stand out above the other?

I'm a HUGE fan of simple carbon steels as well as traditional knives, so I think I will keep that Spyderco extra fine around. It might be fun to have some stones that provide different sorts of feedback. And after watching some videos of Jdavis882, maybe I can use it to refine different freehand techniques without doing too much damage to my blade.

On the note of having different stones... I have the opportunity to purchase a brand new 10" x 2" hard arkansas and 6" x 2" surgical black arkansas stone for under $60 and I'm having a hard time resisting, even though I already have a 8" x 2" soft and 8" x 2" translucent. Talk me out of it, tell me I'm crazy!

Yea... I think I'm starting to realize that one can never have too many stones! This could end up being an expensive (but fun) endeavor, lol.

It's good to know that ceramics can have some use even on the hardest of steels. :) I like my DoubleStuffs and SharpMaker so much, I doubt I would have been able to get rid of the Spyderco Ultra Fine benchstone anyway. My wife calls me a pack rat, but I do at least occasionally get the last laugh when the doodad from five years ago that I put in storage comes in handy.

Another vote for Atoma. I'm going to pick up their 120 at the very least. The finer grit stones are a bit more than double the price of the DMT and Ultra Sharp plates, so I'll have to think on that. They definitely sound super high quality though!

Do you avoid the formaldehyde resin based stones because of the chances of inhalation or another reason (if you don't mind me asking)? I think I've read somewhere that the majority of the formaldehyde based resin stones are water soluble... Which sounds like a bit of a negative to me.

I completely forgot that the Spyderco Fine and Ultra Fine were the same stones just finished differently! I wonder how easily an amateur like me could refinish one side to make it slightly coarser...

I was actually JUST watching a video by him (and Jdavis) and came to that same conclusion. The UF isn't going anywhere, lol.

You have the soft and translucent, I wouldn't invest in any more Aransas stones.

Between DMT and Ultrasharp at same price I'd go with the larger size. All else equal, flip a coin.
 
If the $60 doesn't affect your other purchases, then I'd personally have a hard time saying no. But I have a soft spot for Arkansas stones so it would be much more "me wants" than practical. The 10x2 would probably put me over the top. :)

The bonded diamond stones that I came across when I was in the market, all used Phenol-formaldehyde resin to bond the diamonds.

With some adhesives, formaldehyde makes everything better in terms of performance.

I avoid ALL products with formaldehyde, whenever possible, because its known to be a carcinogen.

I work in an industry that in recent years has largely been forced to remove formaldehyde from their products.
 
Dmt for sharpening
Atoma for lapping

I can kill an Atoma plate in 6 months of sharpening.

I've had my DMT plates since 2008...

Good to know about the differences in longevity you've experienced between plates. Do you think the different plates require a different technique to get the most life out of them or do you think it has more to do with the bond?

I just had my local shop put in an order for an Atoma 140 and a Coarse/Extra Fine DMT. :)

Still struggling with holding off on the Arkansas stones... They're so pretty, lol.

I think that's where I'm at too... Just a want. I can't imagine the Hard Arkansas would give me anything over the Soft Arkansas I already have, but the extra length sounds nice. And with the Surgical Black... I know it's the same as my Translucent, but they're so damn gorgeous.

Fair enough!

I can't believe you are seriously discussing water soluble Venev diamonds.

I don't know that I would say it's being seriously discussed... I don't even know if it's true or not. I just remember reading somewhere (I thought it was here, but I can't find the thread), that urea-formaldehyde resin bonded stones were water soluble and you couldn't soak them. I could be completely wrong though. It wasn't meant to come off as accusation or anything, sorry if it came across that way.
 
The venev stones still aren't perfect, but much of their issues have been straightened out. The biggest issue initially was with their finer grits, the F1200 and F2000. They would leave scratches larger than the size of abrasive in the stones. They figured out this was caused by particles in the stones binder. This was solved when the released their new OCB stones, at least in the 1200. The 2000 still has the same issue to some degree. However I know in my and few other respected sharpeners opinions, the F800/F1200 OCB stone is one the best options on the market for bonded diamond stones. The lower grit non OCB stones are good to go. The only other issues are with flatness out of box. Just give them a good lapping or two and they are fine.
 
D Diemaker are you willing to disclose if the resin you use contains formaldehyde?
I looked at the MSDS for my resin and it does not state formaldehyde as one of the ingredients. When I was prototyping the first Matrix stones I called them up to make sure this resin was safe for this application and was told there would be no reason the cured resin would not be considered food safe by the FDA. Granted this was one call to their technical department so don't bet the farm on it. I do know this stuff is pretty safe to work with as long as you don't try eating it before it is cured.

Baron Mind, how do you lap the Venev stones? I tried loose abrasive and it didn't do anything noticeable, either in thickness or how it worked. The stone I tried lapping was out .008" over it's length.
