I sharpened a couple of knives (A Victorinox Paring knife and a Shun Shimi) with the Wicked Edge. I used the diamond "stones," all of the ceramics, and strops. The final one, balsa, ends with .5 micron diamond paste. Those are probably the sharpest I have ever done. They easily passed a horizontal, one-handed, tomato slicing test (thin slices) and are probably sharp enough to shave comfortably. I will sharpen one with the Edge Pro with the full set of Choseras this week to compare.
