I know of a professional place that sharpens knives in MSP, and I've heard they do a good job. Haven't checked into the prices, etc. However, I saw a sign in Lunds/Byerly's (grocery store) meat counter that they sharpen 3 knives in about 24 hours. Free. Does anyone have knowledge if the freebie knife sharpening is done well? or should I go with the professional?
