Anyone have the new 3 micron diamond stone platens? 3 micron diamond stone on one side, glass platen on the other.

Where does 3 micron diamond compare to 1600 grit ceramics

Would it be a huge jump to go from ceramics to 3 micron diamond ?

The W.E. 3 micron plate is made by DMT... and is the same as their EEF stone. While rated 3 micron, it actually finishes much more coarse, and has a long break in period before it will ever perform at the 3 micron level.... (it will perform coarser than the ceramics for quite a while).

Don't know, that's why I asked. I'm still learning the grit progression of different materials. As I have learned grit/micron size from different materials cut differently and leave different scratch patterns. We have diamond, ceramic, paste, spray, sand paper. Aluminum oxide, silicone, and diamond lapping films. Different types of stones and glass abrasives. And on top of that different grit grading systems from different parts of the world. Even the conversion charts don't all agree. I'm having best results with diamond stones, then sand paper, then lapping film, then leather strop with paste. This has become more confusing then the metric system, lol.
 
Metric system way easier to do engineering calculations than English

But I do second your opinion on all the different ways we struggle to take a piece of steel and put an edge on it

Yea, I know, metric system is very easy but when I was in 3rd grade my teacher swore up and down that metric was here to stay, lol. Learned it and it never became the standard here in the US, it's both, lol.
 
Just redid my 943(it still had a slight recurve) it came out as good as I can imagine possible, completely scratch free to the naked eye even in the sun and almost clear under the scope, a complete mirror. No ceramics, no lapping films. Went back to 1k diamond stone then sandpaper at 1200, 1500, 2000. Then leather strop at 5, 3.5, 1, 0.5. I did one hundred strokes per side in each direction per grit including the 1k(1k was edge leading both directions). Guess that's a total of 1600 strokes per side total. I'm afraid to use it now, lol. Pics look the same as before but I know.

Seems like you are figuring out what works best for you. As others mentioned, the scratches are not nearly as deep when the stones break in and that helps make mirrored edges easier. Most of the time I start at 600 diamond to 800 diamond to 1000 diamond, then sandpaper up through the about 2000 before strops. Works great for me. I have a Mini Grip that I sharpened like that and it still very sharp a couple months later.

I have the ceramics and use these occasionally. Thanks for starting the thread. Lots of good info here.
 
BM 490, no ceramics. 800-1000 diamond stones, 15m, 9m diamond film on aluminum blanks, 6m, 3m diamond film on glass blanks, 5m/3.5m leather strop, 1/0.5m leather strop. Might be able to skip the 15m diamond film when my stones break in a little more. Take your time with the xxx-1000 diamond stones to get get the heal, tip and bevel even and the previous scratches out and the rest is a breeze. This blade was s90v and the diamond stones and lapping films cut just like it was s30v. Same with a s110v Para 2, these stones and films cut great.
