I have not had much luck in the past with ceramic, diamond impregnated or steels.
I did catch a comment somewhere (maybe here) that if you could find and old "Sheffield" steel, they work.
I found one at a flea market for $2 and it seems to make a difference over the several others I have had a tried to use.
I have only been using it on the kitchen knives (some of which are variants of shop mistakes), and still have to work out the best process, but it has promise.
I was told by my mentor that if you use steels, you need smooth ones for softer blades and a textured surface for the harder hunting styles. You supposedly can freshen them up
with a 120 grit on a belt sander. Still working on that bit of info.
Some time we should keep records for a year on how many self inflicted cuts we get. Winner gets a box of bandaids.

Knives sharpened on the Edge Pro just get a couple licks on an impregnated leather strop and are back to work for a couple more iterations before back on the fixture.
