When shopping for kitchen knife sets, more professionals are turning to ceramic knives. Although a relatively new concept to some, they are a great alternative to stainless steel knives. Ceramic knives' blades stay sharper longer than steel -- some don't require sharpening for years. They will not rust or give a metallic taste to the food you're slicing or cutting.
Be sure to keep ceramic blades out of the dishwasher, though, as they can chip. Hand wash instead and wipe dry.
