Would a DMT monocrystalline stone (10in duosharp coarse?) last long
flattening a Shapton stone? (I realize the DRLP is itself a
diamond-bonded stone, but there still may be something special that
Shapton does to make it suitable for its stones.)

Thanks for your comments, Steve.

the problem is they wear everything else out pretty fast. When I first got them
I used drywall screen. I would get maybe at most two flattening out of a sheet.
if you can get a flat metal plate you can then just use the grit to do it. that
would be a cheap way.
