For what it is worth, I currently have 3 "different" honing setups:

-DMT 1200 followed by coticule(s)
-DMT 1200 followed by an oil stone, followed by a CrOx strop
-local slate with varying levels of slurry

The first two setups give me consistent results on most razor blades and the local slate is hit or miss... it works better with old silver steel, India steel or old tools. The local slate slurry excels at removing rust, so I am using it a lot on my hand tools or as a first stone on rusty razors. It also successfully put a bevel on a razor that had been baffling me for years.
