Should I buy the diamond rods for this?

Pablo, the only time you need the Diamons rods is if your planning on changing the angle of the bevel. Lets say you are trying to sharpen at 20 degrees per side, but when you use the other stones, you notice your stones are not touching the apex of the blade. Then you would need the diamond stones to set a new bevel to match the proper degree required. The diamond stones does this job fairly fast and incredibly well. Hope this helped, if you have any more questions. Post and Ill try to help!

Will this sharpen ceramic blades?

No, this would destroy a ceramic blade. These are very rough and are designed to take off a lot of metal when reprofiling a blade. Ceramic is too delicate.

What is the Micron of these stones and grid if you have any information? Thank You Have a great day!

i dont know the micron for the diamond stones the grid is 400 microns for the medium stone is 20 fine 9 ultra fine7 hope it helps you

Are these poly-diamond infused of mono-diamond infused?

The spyderco catalog for this product (204D) doesn’t specify, you may check the the bladeforums site for extensive discussion. I’ve found them effective on my harder steels like S35VN and S90V. My Benchmade 940-1 in S90V came dull as a butter knife and forty or so swipes on these diamond rods got it pretty well on its way to shaving.
