I found some good diamond PSA films that I can get directly from 3M. I’ve been pleased with the samples.[/quote]
Does that mean that you are at least seriously considering having some for resale?[/quote]
Yes, I’d like to offer them. I think they have their place for sure in the scheme of things and provide a good way to keep bevels very flat down to a very fine grit.
The 3 micron diamond plate would be similar in grit to the 1600 ceramics but works in a very different way. The Micro-Fine fine stone is much finer, especially if lapped. The combo should be a great finishing and maintaining step.

Ah ok, so the Micro-Fine fine that you refer to is that the same ceramic stone as the one on the MicroFine ceramic paddle that you already offer?

Yes. I’m just thinking of a new combination for the fine stone w/ the 3um diamonds as a very fast, effective finishing tool for everyday type edges.

Clay I’m back to confused? Lapp a diamond plate? Can you please just give me a very brief explanation?
The Micro-fine fine stone is a ceramic stone… that’s the one he’s talking about lapping.

II definitely like the idea but since I already have the microfine paddle my wishful thinking would be a diamond paddle (with both coarse and fine sides) that would fit right in after the current 800/1000 diamonds (because that’s where I have the biggest problem getting the scratches away). (maybe it’s just me that needs more time/practice with the superfine and microfine ceramics…)
That issue will probably go away on its own as your stones are broken in, especially your 400/600 and 800/1000 stones.

Clay, Just curious if any progress was made with the new stone combo? I guess I’m kinda excited to see the new combo and what you decided on, if anything yet? :unsure:

The new 3 micron stones should be shipping to us today or tomorrow. Once we have them in I’ll do some sharpening progressions and see how the combo works. I’m thinking it will be great.

Thank you very much sir! Very excited!
We got the new 3 micron stones in yesterday. I mounted up a pair and started some testing. At first they were pretty coarse and needed breaking in so I gently rubbed them together a few times. Next I sharpened my EDC, just touched it up really, to see how it would change the finish and the cutting ability. I’d had it pretty well polished already from the Micro-Fine stones and a little stropping. After using the fairly new 3 micron stones, the edge was till shiny but not as polished as it was before I started. It cut very aggressively though didn’t shave impressively.
Today I started a progression from 800# diamond to 3um diamond and then strops from 3.5um> 1um> .5um on cow leather and then .25um on kangaroo. Under the microscope, there was an obvious difference between the 800# and the 3um diamond plates - just about exactly what you’d expect in terms of scratch size. I wish now that I’d taken an image of the junction between the 800# and 3um bevels to illustrate the difference. I did take photos of the rest of the phases though. Here is the blade after the first sharpening with the 3um plates:
[color color=#0000ff]3um Diamond Stone - 2000x[/color]
I measured a fair sample of the scratches under the scope. The largest were just under 3 microns and the average was approximately 1.5 microns which makes sense - you’re almost never getting the full diameter of the particle in contact with blade at any given time, usually just a corner or facet.
[color color=#0000ff]3.5um Diamond and Cow Leather Strops - 2000x. 20 Strokes per side.[/color]
[color color=#0000ff]3.5um Diamond and Cow Leather Strops - 2000x. 70 Strokes per side.[/color]
I lowered the angle by two degrees prior to stropping.
I went on through 1um and .5um and then finished at .25um:
[color color=#0000ff].25um Diamond and Kangaroo Leather Strops - 2000x[/color]
I then went back and restored the micro-bevel that the strops had erased with the 3um diamond stone:
[color color=#0000ff]3um Diamond Plate - 2000x[/color]
Here you see the junction between the 18 degree shoulder at .25um and the 20 degree micro-bevel at 3um.
[color color=#0000ff]3um Diamond Plate - 2000x[/color]
In this last image you see the edge after the 3um stones. The difference between the edge in this image and the first is fairly pronounced. I think there are two factors contributing to what we’re seeing:
In the first image, I used the 3um stones on an edge that had been sharpened with the 800# diamond plates so the edge was already a little ragged
The 3um stones continued to break in as I was using them and gave a much cleaner edge the second time around.
Next I used the fine side of my Micro-Fine stones:
[color color=#0000ff]Micro-Fine Fine - 2000x[/color]
[color color=#0000ff]Micro-Fine Fine - 2000x[/color]
In the image above, you can see the junction between the bevels made by the Micro-Fine fine stones and the .25um diamond strops.
I lowered the angle again to 18 degrees and used the .25um kangaroo strops. I wanted to see if it was viable to go from 3um diamonds to the fine Micro-Fines and then to the .25 kangaroo strops:
[color color=#0000ff].25um Kangaroo Strops - 2000x[/color]
Overall I think it was very successful though I’ll probably add a .5um kangaroo step in between the Micro-Fines and the .25 roo strops. I think a great progression would go as follows:
1000# diamond> 3um diamond> .6um micro-fine> .5um diamond on roo> .25um diamond on roo
I went ahead and dropped back to .5um diamond strops to test the theory. I did 50 strokes with the .5um strops and then another 50 with the .25um strops. Here are the results:
[color color=#0000ff].25um Diamond on Kangaroo Strops - 2000x[/color]
VERY COOL!! :woohoo: This is the first time I have seen a pic that high of magnification and on the end of the blade. I can see the “V” angle very clearly. Would you say that it is “super imposed”?
I just can’t believe how much I learn on this forum! :woohoo: B) 
Thank you Clay!

I’m pretty sure that what you’re seeing there is a reflection of the edge caught in the immersion oil that I use with the 2000x lens. The angle of the entire blade is only 20 degrees from horizontal making the bevel close to perpendicular to the lens.

Looks very impressive! The results you obtained and, as always, the pictures.
Seeing this now I’d definitely go for a 3mu diamond/.6mu ceramic paddle combi.
Which diamond sprays do you use, by the way? Poly or mono diamond?
