See if there is a folding sharpener with a grit more coarse than the Diafold Coarse (325 grit) but not as coarse as the extra
Coarse model. Will be using for some light repair and reprofiling. Any ideas are appreciated.
 
Eze-Lap makes a folding diamond sharpener with an extra course plate (150 grit), but note that it is only available in a one-sided configuration. They do make dual sided folding sharpeners, but their site doesn't list any with an extra course grit.

DMT apparently also sells a dual folding sharpener with a extra coarse plate, but they describe it as having a 220 grit (60 micron / 220 mesh <-- whatever that means).

Idk how accurate or comparable the grits are, just something to keep in mind.

If you look at the The Grand Unified Grit Chart, you will see that the DMT course is 45 microns and the extra course is 60 microns. That isn't a very big spread, and I think it unlikely that you will find something that falls in between. But look at the chart yourself, you might find something I missed. Gritomatic has a version of the chart linked to many of their stone pages.

O.B.
 
You can find some Chinese plates on AliExpress that work very well, is great value for money and will last a long time. The only drawback is it will take some time for delivery.
 
Might also consider using the Extra Coarse DMT anyway, to set the edge bevels. Then use something like a Fine or EF diamond, or even a medium or fine ceramic, to put a finer and very minimal microbevel atop the coarser apex in just 2 or 3 passes per side. Such a combination can produce some very aggressive-slicing edges that will cut to a finer degree than the XC-finished edge alone, but still more aggressive-slicing than an edge produced solely on one of the finer hones.

And as mentioned, sometimes a similarly rated 'Coarse' hone from another brand will perform to a slightly coarser finish than the same-rated DMT. One of the hallmarks of DMT's hones, in my opinion, is their tendency to produce a more consistent and refined scratch pattern relative to their rated grit. I view that as a good thing, myself.
