Hello I just ordered the dmt xxfine(8k equivalent 3 um) Besides breaking it in, any feedback on this. I have the 120, 325, 600 1200 and now this one. I like the speed and ease of use, no lapping. Then I can go to 1 um film to finish. Ive been making the jump from dmt 1200 to 3 um film with no issues. I only use Norton 4k if I get microchips. The other day I got a decent hht off the 1200! Maybe the stars were in alignment. I also see they have a 2200 grit ceramic, any info on this as well? A 4k equivalent would be perfect, maybe some day.

If you do a search on the subject, I think you will find that around 2008 or so, there was a small consensus on B&B that felt that a DMT progression would deliver a decent edge. So if it's working, all power to you! Since then, I fear that we may have become more finicky about things. Apparently, there is a DMT medium extra fine stone out there as well, at 4000 mesh, which would place things between the 1200 and 8000 mesh, should you so choose.
I use the 1200 grit for starting with bevels..anything under that would be to remove chips...the DMT1200 starts the edge...I use a combo coticule to final sharpen and polish

Thanks for the link! I was looking at dmt website and all over and couldnt find it. I just ordered it. Thanks again!
The DMT 8k is a very interesting tool. It can give you an edge that I have YET to see matched from a hone in full profile under a scope (400x, literally bullet straight 100% flawless edge in profile... very similar looking at the edge to extremely high grit pasted strop results) when used with no pressure, ironically this edge won't even pass arm hair test until you strop it (which will bring it to performance I'd expect from a 8k mesh edge. I assume it's a very even distribution of VERY low size variance diamonds with no slurrying that creates this look. I don't get the same effect off any of my other grit DMT's, though.
It actually works better or at least more like most 8k's with a touch of pressure. Now I'm not sure why exactly it creates this "false" edge under scope or why this effect makes the edge less effective and disappears with stropping or with any further honing (if you make it by mistake, one pass with slight pressure will remedy it). Could be some kind of foil edge effect, could be something else. I tried to figure it out for a bit, but eventually decided that I did not care since it really didn't have any effects on the honing. In sum, if you're having troubles with the edge not cutting well coming right off the EE, give it a pass or two with slight pressure to "fix" it. Once you're confident in your usage of the EE, you can skip this, since going to the film and honing on that will also remedy the issue... that said, I still like to use very slight pressure with the EE just as a general rule, it completely eliminates this issue and speeds up cutting.
The medium fine hone is interesting, and a few years ago, I'd have bought it in a heartbeat, but honestly, it's not necessary. The jump from EF to EE on DMT's is not hard to make at all. I can do it in a minute or two on hollow ground razors. Maybe if you hone a lot of wedges or kami's it's worthwhile, but I wouldn't be the person to ask about that.

Im looking forward to using it. The foil edge plays a roll in everything, I used to scratch my head sometimes when I couldnt pass hht , now I give it a few more laps on what I was using and there you go. I got a decent hht off a 1200 last week. Never had that before. No strop nothing. I usually look for hht after the 8k or 3um film. Regarding the jump, I sometimes work on some vintages that havent seen a flat hone in 50 years, I use the 4k to remove any microchips I might get. ANd some Gold Dollars seem to be a little prone to microchips(about half of them) coming off the 1200 dmt. I really find a 10 minute soaking to be a real pain. Especially when I dont know if I need to use it. If these dmts work out as i am expecting, I will sell off my 220/1k and 4/8 norton and a flattening stone I had and even my naniwa 12k. I got a decent amount of film, should last for years. Im thinking the edges off the 1 um film are the best overall if you consider sharp and durable. I use crox after and got some nano cloth with .1 cbn that IMO makes the edge that much more sharp and smooth.
I find it kind of interesting that the new DMT is a ltd edition - and only in 8x3" size.
Seems strange - maybe they're testing the market to see if there's interest?

Maybe they're just thinking about straight-razor sharpening for a change. ;-)
If we're talking the 4000/6 micron DMT here, where do you read that it's a limited edition stone?
The 8000 mesh DMT needs some learning, but can be a nice stone. Very very fast, 1200 to 8000 isn't a jump for that stone, maybe 30 strokes or so. I maybe rebought that stone two or three times, I am considering buying one again 
The speed just can't be beaten at how fast you can hone an absurdly hard razor with a DMT EF and EE, and you can finish with a fast finisher after that.

its on the DMT site - in the Diafine section.
You're right. I just checked. Probably did it for some big sellers like Sharpening Supplies. Good thing I don't have any DMTs, apart from a 220/325 duo-sharp for lapping.
I have a few, I hardly ever put a razor on one, when I do it's usually the 600x, then I go to an 800x Chosera to clean up the mess.
