Hello Sharpeners, So, the massive marketing machine is grinding on me and I've found myself intrigued by these knives with the row of elliptical grinds that supposedly help food like potatoes not stick to the blade. I've always chalked them up to gimmicks but like I said, I'm curious. But, one thing I really do wonder is if and/or when, these "circles" will or would interfere with sharpening? They seem so close to the edge... Your thoughts welcomed.
