Like what Barry said. The XX (DMT color coded black) is rated at 220
mesh.

I have a folding red/green Duosharp for knives, scissors and stuff and
I really like it for a quick job on my crappy kitchen knives and it
puts a very good edge on my garden bypass pruners using the green
side.

Diamond stones are great, but to me they're expensive for flattening
plane irons and chisels, but are good for flattening waterstones. If
you do get a diamond stone get one with monochrystaline diamonds as
opposed to polychrystaline. The diamonds are uniform on mono and they
wear longer.

I would assume that a lower grit diamond would be what you want for
flattening waterstones? What grit would you recommend?
