Pros: Effectiveness, Ease of Use
Charlie's Wheel of Fortune Magic
I have collected hunting and kitchen knives for many years, and long ago learned how to sharpen a knife properly. Charlies saves a lot of time on knives that are hard to sharpen or that are near sharp, but not quite smooth shavers. I would not use it on a knife that needs coarse sharpening or re-shaping, but for final edge and honing it is amazing.
