We think not! Here's the thing: Separating an egg doesn't require any kind of gadget at all. Try one of our test kitchen's two recommended methods instead, and you'll be glad not to have another tool hogging precious drawer space.
For cooks with good hand-eye coordination:
Crack an egg in half, then slide the yolk back and forth between the halved shells, letting the whites drip into a bowl. A tip: Make sure to crack your egg with a firm tap on the rim of the bowl to avoid jagged edges that can piece the yolk.
For those who want an easier, if messier, way:
Crack the egg into your hand and let the white drain through your fingers into a bowl. You'll need a good hand-washing afterward, but what you won't have to wash is another tool!
BTW: If you're still gung ho about buying an egg separator, feel free to spend $5, not $15: Plastic models work as well as pricier stainless steal ones.
