All you guy's that never tried an electric knife are still in the stone age. The only reason to use a regular knife is if there is no power. I have used a black & decker slim grip from wal-mart for 6 years and never had to do anything to the blades. There isn't a point on them to poke yourself if your not paying attention and the only time they cut is when you have the trigger pulled in which is a big plus if you have a 3yr old sitting on the counter beside you learning.
