Picked up a couple of these because my old ceramic was wearing out. They seem a little toothier than what I had. Anyone know what mesh or micron these are?
 
I have one of those rods. Hard to say for sure but I would think its somewhere in the 400 to 600 range. I'm basing that on the other ceramic rods I have that are finer.
 
Is that the brown ceramic sharpening steel? If so, I love mine. I use it almost every day. Just a couple of light passes on each side and the kitchen knives are back to shaving sharp. I think the slight toothiness is helpful.

Good sharpening,
Dave
 
Ceramics are very hard to pin down, in terms of actual 'grit' or particle size. And even when particle size is specified, the ceramics usually don't perform accordingly, because of the ceramic processes used to make the hones (different binder materials into which the particles are embedded, and how the stones are surface-finished).

For example, Spyderco's ceramics are all produced using the same size/grade of aluminum oxide; their 'Medium', 'Fine' and 'Ultra-Fine' stones are each made using particles that are ~15-25 microns or so (see quote below), which is much larger than almost any other 'Fine' or 'Ultra-Fine' abrasive (like diamond or silicon carbide). The way the hones are finished is what makes them perform to a given 'grit spec'. And even then, the 'spec' given by a manufacturer likely won't sync up with similar products by other manufacturers, so direct comparisons to others, based on published 'grit', are usually still meaningless.

From Sal Glesser (Spyderco's founder):
" All of the ceramics use the same micron size (15-25). the different grits are created by different carriers, different firing techniques and diamond surface grinding.
