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:

.25um Kangaroo Strops - 2000x

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:

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.

Dam learning curve!! :blink: Still very cool!

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?

That is a question... Interesting?
I have always wondered if we could quantify the differences...
Still do!
Have yet to see anything quantifiable, other than "discussions" on the topic.
Perhaps something that Clay might want to explore ... during his "leisure" time...

:evil:
Have you documented any differences Mark??

No I haven't. But I can see that the stuff Clay used works very effectively. Do you notice any differences?

No I don't. But my measurement tools are crude. I have not done any controlled testing either, such as number of strokes required to get the same results based on the ability to test that I do have.
I still keep thinking about building one of those sharpness testers.
I really like to "see" what is going on, but I guess the real criteria for sharpness is in the cutting ability of a blade.

BTW, thanks Clay for doing this!
