Hi,
Anyone own a 600 Ultra sharp diamond stone? If so how have they held up long time use? I read that Ultra sharps are coarser than say DMT. Dmts do finish nice but the newer production (only the fine plates, above 600) seem to have patchy diamond displacement. The coarser Dmts are better and more consistent.
 
while I have the Ultra Sharp plates in 300, 600, and 1200, along with the 300/1200 combo plate, the 600 Ultra Sharp is my favorite. Its coarse enough for (minor) repair work, and leaves a nice, aggressive edge. I typically use that one plate to bring my mother-in-law’s kitchen knives back to life.

I have had these for a while, and they are still working great.

I agree that the DMT’s are pretty much crap these days. The Ultra Sharp‘s are a great value, and seem to have proven themselves over time for me, as well as a bunch of other people.

Yeah I agree, the finer stones aren't what they used to be.. The DMT do finish nicely. The xxc Dmt is very durable I use it to lap water stones and it has held up well.

So would you say the 600 is coarser than '600' grit compared to other stones? If so that good, for me..
 
Sad to hear of the DMT line not being what it was. I haven't bought a new one in some years now.

If you mean comparing the Ultra Sharp 600 plate to a stone like a Shapton Glass 500, the 500 will cut quicker and finish better.

If you are asking if the Ultra Sharp 600 feels/works like a DMT coarse (I believe that's the 600 grit), then they are basically the same, but the Ultra Sharp will be higher quality and have a much more even look to it.

The Ultra Sharp diamond plates are what I take when we go over to my Mother-in-law's for holidays, or family gathering dinners. I like them for the fact that they are quick enough, but less messy than water stones. Plus I can pack them up in my little travel case easier.

The DMT Fine is 600 grit. The Coarse is 325 grit as I recall.
 
Diamond stones of this type - basically grit stuck on top of a metal plate - start out coarse than their strict grit rating, simply because of how they are constructed. As opposed to resin stones or grit on strops.
Since diamonds are friable, they wear in to the stated rating.

I believe HeavyHanded - a sharpener of great experience - has had good things to say about Ultrasharps.

So the ultra sharp 600 when new it finishes like a brand new DMT/325?

No, I meant to say that the Fine (600 grit) DMT and the 600 grit Ultra Sharp were pretty much the same at the start from what I remember.
 
Anyone had a chance to compare the Ultra Sharp plates to Atoma? I've recently started using Atoma plates, and am quite impressed, compared to some very old memories of those DMT plates with holes and red/blue plastic.
 
I've had the full set of ultrasharp plates for a while, all the plates are extremely aggressive when new especially the 300 and 600. My 300 ultrasharp plate, I have used it from leveling many of my water stones and even harder novaculite stones as well as a few ceramic stones. Have used it with lubricant and even dry on wood working tools, knives as well as leather working tools and still not fully broken in yet. I thought spending a couple hours straight on my 302f would basically destroy it especially with the amount of force I was using to level the ceramic stone however barely phased it, really quite impressive. IMO if you want work horse plates these are hard to beat, if you want plates that will produce a better edge the DMT's are probably a better bet. The ultrasharp are taking so long to get truly broken in for me I can't say for sure if once broken in they're as good as DMT's. As far as diamond I tend to get the best edges off my interrupted diamond DMT's plates/stones. Just my two cents.

The Atoma are IMHO the best diamond plates you can get. I'm not sure about longevity because I haven't pounded heck out of em yet, but for quality, speed, feedback, they work very well. That said I have been using my 3k Ultrasharp as a finisher since the Atoma line only goes up to 1200, and its a somewhat coarse 1200 at that.

Overall for price, the Ultrasharps are a great value and hold up to abuse better than any of my other plates, my only complaint is that they don't make a 120 grit or similar.
