3. Electric Knife
To create the largest possible mess in the smallest amount of time and completely butcher (not in the good way) a perfectly nice piece of meat, we recommend you buy an electric knife. Or a hedge trimmer. They're basically the same thing. Good luck with that.
2. Egg Rings
From personal experience, we can say that not once have these ever worked. The rings don't sit flat in the pan - any pan - and the eggs dribble out of the flimsy sides every time. Do not waste your money on these, despite any dreams of perfect eggs Benedict you have in mind.
1. Clam Knife
If you can tell us that you prepare and eat clams with enough regularity to merit owning a clam knife, you can have us over for dinner and prove it. We'd love to come over and rifle through your drawers, where we'd most assuredly find every other useless piece of crap on this list as well as things we didn't even get around to like melon ballers, avocado slicers and egg cups.
