If I were to get an EdgePro, it would definitely be with the GlassStones.
I found the unit easy to learn, but as with all sharpening you will forever be chasing the dragon's tail. Even with an EdgePro, there is always improvement to be found...it's a fun chase too.
I like the Tojiro honesuki a lot.....but I like carbon for that particular knife style for some reason. A protein specific knife harks carbon in my tiny brain.
You've already got the itch for a carbon core, stainless clad. Get it!!
