Chef’sChoiceG203 Hybrid Knife Sharpeners uses Diamond Abrasives and Combines Electric and Manual Sharpening for 20-Degree Straight and Serrated Knives, 3-Stage, White (SHG203GY11)

My wife love it

What can I say, I've only used this once. That's all it took to get my knifes really sharp. They probably aren't as sharp as if they had been professionally sharpened, but they are very sharp. Certainly sharp enough for the average home cook.

There were no instructions included in the package. Do not know how many times to slide each knife. Do not know how to use the slot I suppose is for the serrated knives. It seems to do nothing. Dead.
