A monocrystalline diamond surface electroplated to a perforated steel plate. The perforations collect swarf so the surface does not clog, and the plate stays flat indefinitely, which is why this doubles as the lapping plate for your waterstones.

Diamond will cut abrasion-resistant steels that a natural or ceramic stone struggles with. Use it wet or dry; water keeps the surface clear.

Every waterstone dishes, and a dished stone rounds over the bevel you are trying to flatten. If you own waterstones you need one of these or an equivalent.
