I've never been a fan of electric knives. I feel like they are mini chain saws, and if you need a chainsaw to slice it, then I don't want to eat it. LOL. know what i mean? (No offence to anyone who uses one.!)
I do most of my Slicing with an Electric Knife.
However don't pick on Chainsaws---I've done some of my Best cutting with Chainsaws too:
