I know there's not many people who use diamond hones for razors, but, I found this little tidbit in my lee valley catalogue and figured it'd be good to know. It's about monocrystaline vs. polycrystaline diamond hones.

The extra fine by DMT is only 9 micron. This is about equivalent to a black arkansas stone. Great for a knife but a little course for a razor.
Norton claims translucent and black arkansas stones are about 5-6 micron. Fine arkansas stones actually work fine for razors because they're so slow cutting, they produce a much better edge than you'd guess based on the grit diameter. I've got a razor I honed on pink translucent that shaves great, about like you'd get from a barber hone.
It says here (in the last paragraph)..

..that diamond stones are getting popular for reflatining medium to course waterstones, but diamonds stones will eat up 8000 grit stones like nothing.
Is there such thing as a verry fine diamond stone or hone (good enough for straight razors)?
Shapton makes diamond hones in a variety of grits, some are incredibly high grit. I don't know of anyone that uses them for razors, so, whether or not they work well with straights, I don't know.Quote:
