I have been using the Edge Pro Apex for several years and love it. Back in the day I used the John Juranitch, Razor Edge System based/born in Mn for years, but found it too limiting for my needs. I have made knives, both straight and folding/locking, reconditioned and collected knives in the past, and have always pursued that perfect edge and while not perfect, it brings it one step closer without needing a lot of skill. Our house does not own a "steel", but we use either highly polished SS rods, Razor Edge, or fine ceramic rods to keep the edge in line after each use.
I also have ceramic knives and wondered if you have used their system/stones to sharpen them, assuming you have ceramic knives?
