00 Chef'sChoice 15XV EdgeSelect Professional Electric Knife Sharpener
The Chef’sChoice 15XV is my top electric pick for fast, consistent results, converting a standard 20° edge into a higher-performance 15° edge. It uses 100% diamond abrasives plus an advanced stropping stage, and the flexible spring guides help maintain the correct angle automatically. Initial sharpening takes about a minute, and touch-ups are around 10 seconds.
