I got a Wusthof Classic knife for my birthday. Would sharpening it with a relatively inexpensive sharpener cause any damage to the blade or just not give it the best edge. I have a little sharpener I got on Amazon.com that you draw the blade across a disk the size of a dime or smaller. It has two slots one for really dull and one for everyday sharpening. It a JA Henkels Twin sharp for about $20 and Wusthof makes one that appears similar for the same price. I am not fanatic about a super sharp edge, I just respect the makers of the knife and don't want to hurt it.
