Query: Waste of money

I don't know if I just got a bad one or what but it does nothing to my knives. I decided to purchase it soley on the great reviews. I have several very nice Wusthof knives that were in need of sharpening. Ordered this sharpen tried it on everyone of of my knives then had two other people try to see if it was just me, the knives are soo dull you can literally run the blade across your hand and it does nothing. Very disappointed in this product.I give it one star for the fact the scissor sharpener worked well.
