Aero Knife: Does it work?

Anyone who does a lot of cooking knows a good, sharp knife is a must for all the chopping and slicing. So when a celebrity chef tells you about a great new knife, you tend to pay attention. The Aero Knife is billed as a knife that cuts twice as smooth, twice as fast and never needs sharpening. But is it worth your money?

Part of the hype with Aero Knife is that it has 60% less surface area, which is supposed to keep food from sticking to the knife as it slices. Promoters also tout the serrated blade. They call it a "new Micro Edge".

For my test, I grabbed some tomatoes, a chilled, cooked turkey breast, and a variety of kitchen knives to see how they compare to Aero. I started with a high-end, straight-edge knife that's more than 12 years old and has never been professionally sharpened. It sliced the tomato just fine, with no sticking.

Next, I used a slicing knife with a serrated edge. Again the knife produced nice, smooth slices with no sticking and no problem. I got the same positive results with a $10 red pairing knife that has a carbon steel blade and a non-stick coating. The popular brand is known for its variety of colors and sharp, long-lasting blades. The red pairing knife also sliced right through tomato with ease. Just for grins, I tried one more heavily-used, small stainless paring knife and again -- more smooth slicing and no sticking.

In the Aero Knife commercial, the celebrity TV chef slices with much more rapidly than most of us. Is it because of the knife? I don't think so. Unless you're a pro, high speed with a sharp knife is a hazard. However, I found the Aero Knife did perform well. It was good at cutting thin tomato slices and the slicing did seem to be smoother and therefore somewhat faster. With the chilled turkey breast, however, while slicing with Aero Knife was smooth, the turkey slices came apart during slicing compared to the straight edge kitchen knife, which produced more solid turkey slices. But, as a general purpose utility knife, the Aero Knife does work.

On a scale of 1 to 4, promotional hype aside, I'd give Aero Knife 3 stars. That said, I did not find it to be superior enough over the other knives I tried to warrant adding another knife to my collection. However, if your kitchen knives are shot and you really need a utility knife, the Aero Knife is worth adding to the list of knives to consider. It sells for around $10 at many Rite Aid, Fred Meyer, Bed Bath and Beyond, Walmart, and other stores that carry "As Seen On TV" products.
