I'm glad JG jumped in here. I generally don't like any powered devices to sharpen a knife. Besides the risk of seriously buggering up an edge, or blade finish, you have to be extremely cautious about over heating the edge apex. I believe it was Roman Landes who did a few experiments that showed any powered sharpening (if not cooled) will over temper the edge, resulting in a weak edge apex. The only way to correct that being non powered (or cooled) sharpening.
Maybe I am a bit over cautious about the whole powered sharpening thing, but I won't do it. I like to err on the side of caution. My luck I would be sharpening someone's knife at a show, the knife would catch in the wheel or belt, and send it into someone's belly. That would ruin the blade finish for sure!!!!
If I was at a show offering sharpening, probably would be a slow speed wet grinder like Grizzly or some of the others. The 320 grit stone on my grizzly cuts fast enough.
