#KnifeSharpenerSystem2 Stage (Diamond & Ceramic) SYSTEM Knife Sharpener for Extra Sharp Kitchen Kn... This a great sharpener and it is easy to use. The color is pretty and will fit into anyone's kitchen or desk. If you want quick and right that works perfect, then is a great product. It's to use and safe for old people, to keep around and don't have to worry about them cutting them selves. It will stay where you put it and snap button to move. My dad likes it said it for the young people who don't know what a wet rock is or how to use it. Then he said to give it to my grandmother for Christmas. I received this product at a heavy discount or for free for a honest review.
