Can anyone tell me about the Spyderco ceramic bench stones? I have a Sharpmaker and the triangular rod flats are not really.flat, the wear marks seem to show they have crown to them. Not the end of the world on the Sharpmaker, but not something I want on a bench stone. Are there any other makers of ceramic bench stones that I should consider?
 
I have both the brown and white Spyderco ceramic stones. At some point I got the bright idea to try and flatten them on my diamond bench stones. Yes they were a bit "not flat", both slightly dished and crowned in places, but flattening them was not a good idea. They both now cut much slower, although they are now flat...

I did the same with one of my Spyderco DoubleStuff hones. It was slightly dished (from the factory). Flattened both sides of it on a coarse diamond hone (DMT DuoSharp). Sort of a mixed bag, in terms of results. It is clearly 'smoother' (less abrasive) than before. However, I'm finding that I like it. I've been doing most of my 'cutting' on diamond hones lately (up through EF or EEF). By the time I'm ready for the ceramic, I don't need that much cutting power anyways. The ceramics really excel at straightening & cleaning up burrs, and mine is fine for that. Being smoother & flatter now, it seems to enhance that a bit. Edges come away a little more refined & polished, when compared to my results before I lapped it.

The raised edges of the hone were the biggest issue before, as it was a little too easy to drag the blade's edge across 'em. Too much pressure at all, and that slightly raised, hard edge of the dished hone creates more problems than it solves.

Even with my little DoubleStuff hone, it took a LONG time to flatten it, even on coarse diamond. I'd hate to think about trying that with a large ceramic bench stone.
