I' ve used a few electric sharpeners before, but I really don' t like them. They seem to grind an edge that doesn' t always match the blade. I have been using a " lansky sharpener" for the last 3 or so years. It has a metal clip that you secure to the blade and then put the stone onto a metal peice that fits into the clip so that you will always keep the same angle on the blade. The one that I bought is the cheaper model with 3 different stones (course, med. fine) but they sell them with 5 stones in them, but 3 certainly works good for me. I' m pretty sure that I got mine for about $20 or so.

Normally I will just sit down infront of the TV and sharpen my knives and it really doesn' t take that long to get a really good edge on them.
