anyone using the DMT double sided diafolds?

I have a coarse/fine diafold. Use it mostly for reprofiling, but also for getting a toothier edge with CPM S60V and just getting S90V sharp (I know Sal Glesser says you can get S90V hair-poppin' with a Sharpmaker, but I can't).

Likes? Narrow enough to be useful with a recurved blade.

Dislikes? Double freehand sharpening, since you have to hold the diafold in one hand and your knife in the other. While there are times when this is okay (plus, it's what I'm used to from the old days with my tiny 1" x 3" hard Arkansas stone), it makes keeping a consistent angle difficult.
 
I have the red (fine)/green(ultrafine) one, great for maintaining an edge in the field. With a thick piece of strop leather under the hone to keep it level with the handle, it can be laid on a flat surface and used for two-handed sharpening like a bench stone.
 
I use the coarse/fine. Just seemed to be the logical choice. And it turns out it was the right choice for me.
It allows me to take out little nicks and put a razor edge back on the knife in one neat little foldable package.
Doesn't work really great on re-curved blades but for standard type blades it is outstanding.
I should clarify that last statement.
The Diafold will work on re-curves, just not to the degree I want. If I'm taking a re-curved blade with me, I take the model "M" diamond rod from Eze-Lap instead.
 
I use a fine/extra fine DMT diafold. I don't let the edges on my knives get dull, but if it does happen, I use this DMT on my 204 (to maintain a correct angle) to reprofile the edge. Unfortunately, once I get the diamond triangles for my Sharpmaker, the diafold will be used only when I need a convenient, easily portable system.
 
I use the coarse/fine one. I mainly use it on the tougher steels that don't respond as well to a Norton fine India or the Sharpmaker.

It also is faster for reprofiling even simple carbon steel blades quickly, or for repairing badly damaged edges.

It is the sharpener that goes on extended hunting trips with me. I sure like mine.
 
I think it depends on user’s liking and preferences. For someone who likes to keep his/her knife shaving sharp continuously makes sense to get fine/u-fine one to touchup the edge with u-fine and to sharpen it with fine. This is also my choice.
However if someone tends to get the knife decently blunt first and just then to sharpen it - coarse/fine would be better choice.

Basically coarse DMT sharpening surfaces work the best way for edge reprofiling but the Diafold is not right tool for this operation exactly because of doubly freehand sharpening as Dave very aptly noticed.

Pluses: very portable – light, compact and not brittle unlike ceramics or arkansas stones, ideal field sharpener.
Minuses: mentioned doubly freehand sharpening, not the best performance on recurved blades.
However I can’t consider these like real minuses, just right tool should be used for each work.
 
I use the fine/x-fine version together with Razor Edge Systems clamps. It gives me a razor sharp edge for my knives.
 
I've got the coarse/fine combo. The coarse is so aggresive that I find it a little rough to use. I picked this combination so that I can sharpen friends very dull knives in the field as well as maintain my own. For my knives I only use the fine side.
 
I use the course/fine combo. I find the course great for stock removal and a fast edge on an axe blade, but gives a hopeless edge!

The fine does not give an edge I would be happy with for daily tasks, it is a little course for me even using water as a lube.

However with high Vanadium steels that I use, diamond hones are a must to break them in so I can finish with the Sharpmaker.

It does its job and is tough, no breaking of the diamonds as far as I can tell.:)
