I read somewhere that a sharpmaker's grit size is 15 microns for medium, 6 for fine, and 3 for ultra fine. How do these sizes translate to the number on wet/dry sandpaper? Thanks.

I see. thanks.
PS: which one gives the finest polish?
Ceramics are odd in that respect, you can't really compare them that way. A 8k water stone, UF ceramic, DMT EEF, and 2k sandpaper are all very close but because of the abrasive shape and hardness they all yield a different finish.
Do not underestimate ceramics...I have seen Spyderco UF ceramics produce hair whittling edges.
All the items I listed can produce the same results but the finishes and feel of the edge will all be different, the steel being sharpened is also a factor.
plus 1 on the steel. At the moment all I have is my SM with medium and fine rods(UF rods and DMT aligner still on the way). However, I can get a really fine polish on my vg-10 E4's edge but I can't get even close to a fine polish on my S30v on my military. Am I right in assuming that this is due to the different steels? or is this also in large part technique related? thanks.
Thank you obssessed. I have a loupe but I think the magnification is not high enough because I can only see the sides of the bevel, I can't really see with it if the edges have met. How much does a good loupe cost? and what magnification is ideal? the one I got from ebay says 30X21 but it's from China.
this is actually very similar to what I've got.

Maybe this is just 3x magnification since I can't really see the edges
