Diamond spray on paper wheel?

Has anyone ever tried this - spraying a slotted paper wheel with diamond spray instead of rouge?

I made up some balsa strops for my Edge Pro. This past weekend I stropped my EDC blade (in 3V) - it turned out real nice. I used a non-slip mat with my EP stones upside down on a table. I started at around 300 and worked through the 600 and 1000 grit stones (maintaining a convex grind) before I hit the diamond spray/balsa strop. I'm thinking that it would be nice to speed up the process. Maybe a belt sander with a diamond loaded strop would work better, but I don't have a belt sander to try it. I could get another wheel for the grinder :D
 
I use diamond compound on both the non-slotted (15 micron) & the slotted (6 micron) Paper Wheels, mainly for use on ceramic knives, but lately also on various high wear stainless steels.

Could you elaborate on the diamond compound your using and its longevity on the paper wheels? I'm having trouble visualizing how the compound would stay on the wheel. I'm very interested in giving this a try.
 
I use my modified Paper Wheels with a mixture of 3M diamond compound and a specialty oil with tackyfier additives to help keep the compound on the Wheels.
The oil also aids in cooling the edge during the sharpening process, and my bench grinder only runs at 1400-1700 rpm, which is slower than most.
After several applications of compound & oil and subsequent sharpenings with this cocktail the surface of the Wheel develops a dark & tacky layer that holds the diamond particles quite well.

The idea behind this method is to combine relatively fine diamond particles with speed, in an effort to improve the cleaner cutting of hard carbides (especially vanadium carbides) in high wear steels on a microscopic scale.
The sharpening process thus far produces only very fine burrs (less plastic deformation), seemingly polished edges (to the naked eye only, as with a jewellers loupe you can see fine scratching clearly) that nevertheless are very sharp (hairwhittling as well as slicing single layer toiletpaper) and have quite a lot of bite.
I'm currently in the process of testing these kind of edges on various media, as well as on longevity.

Thanks for the info! I'll be researching what is available around these parts for some experimentation.
 
Here is an example of the edges i get with diamond compound on Paper Wheels, and the knife is a user Spyderco S90V Military from a Dutch forum member.
It's not a true mirror edge, as with the magnifying glass in my Victorinox SwissChamp i can still see fine scratching, but with the naked eye it's close.
Sharpness is hairwhittling (both to and from the root) and it can also slice single layer toiletpaper with ease.
