We looked for over a year for a GOOD knife sharpener and this is it!!! It takes me about five minutes to do my Wife's knives every two weeks.
This knoife sharpener does an excellent job on knives and scissors. It is very easy to use. It is expensive but it does a professional job and I won't have to take my knives and scissors to someone else to sharpen.
My electric sharpener from Smith's works great. It sharpens both sides of the knife at the same time, so the edge is centered correctly. Also, the circular sharpening wheels create a "hollow ground" edge that's extra sharp - it's like the edge put on knives at the factories of top knife companies. I could not be more pleased.
