I go from an extra fine diamond "stone" to the 0.3 chrome on horsebutt, glued down to a piece of plywood, and pull the bevel across it about 6 times. Usually, I also lay the back of the blade flat on the strop and pull it across a couple of times. Sometimes, when sharpeninig a blade that requires a slip stone, I go directly from a translucent Arkansas stone to the chrome strop.

I never set up any experiments. I don't even have a microscope to analyze scratch patterns or count carbide chipouts. Someone had recommended chrome on this forum a few years ago, and after I figured out that Crayola has replaced the chrome in their green crayons with some sort of dye, the green powder in the above link is what I found. It just seemed to make sense to mix it with mineral oil before wiping it on the strop. I tried it for a while and was satisfied with the results, so I didn't search any further. I was never expecting anyone to ask me to publish a peer reviewed scientific paper on my results. ;^) I just wanted to get back to work with sharp tools.
