Seattle Ultrasonics C-200 review: This is the future of kitchen knives

There’s a type of knife tech often seen in science fiction that revolves around vibrating a blade to increase its sharpness. We’ve seen examples of this in franchises like Star Wars (vibroblades), Evangelion (the prog knife), Dune (pulse-swords) and the Marvel universe (vibranium), but what might surprise you is that the underlying science is sound. By vibrating a cutting tool at high frequencies, not only do you reduce friction, you essentially turn the blade into a saw, as tiny oscillations enhance the inherent sharpness of a blade.

However, up until recently, this tech largely only existed in fiction or for large companies that have the money to utilize the tech on an industrial scale. But that's changing in a big way for home cooks ...
