Imagine a knife that doesn't just cut, but vibrates as it does! I experienced this firsthand at CES 2026, and it's more practical than you might think. During the Unveiled media event, I found myself slicing tomatoes with a knife that, quite literally, buzzed with every movement.
This isn't some futuristic gimmick; it's the C-200 UltraSonic Chef's Knife from Seattle Ultrasonics, launching this month. This innovative tool features an orange button on the handle that activates an eight-inch Japanese steel blade, causing it to vibrate at an astounding 30,000 times per second. The result? Food slices more smoothly, and crumbs are less likely to stick to the blade. Plus, it might even reduce the frequency of sharpening.
But here's where it gets interesting: the blade only moves a tiny amount, between 10 to 20 microns – that's about a quarter of the width of a grain of salt! You won't see or feel the vibration, making it feel like a regular chef's knife, albeit one with a bit more heft. The only giveaway? A faint, high-pitched pinging sound, similar to a wine glass being rubbed, if the blade gets wet.
While I wouldn't say it drastically outperformed my own high-quality chef's knife, the C-200 certainly made slicing a breeze. I effortlessly cut paper-thin tomato slices. The company's representative compared the experience to the difference between riding a bike and using an e-bike – it makes the task more effortless.
The C-200 is the culmination of six years of development, and Seattle Ultrasonics claims it's the first ultrasonic knife designed for home use. Commercial versions are typically bulky and expensive, sometimes the size of a shoebox. To keep the C-200 compact, its internal circuit board is cleverly folded within the handle.
It's also designed with practicality in mind. The C-200 is IP65-rated for water resistance, so you can wash it like any other chef's knife. It also features a removable, rechargeable battery that charges via USB-C.
The first production run of the C-200 has already sold out, and reservations are now open for the second batch, set for release in March. The knife retails for $399 on its own, or $499 with a wireless mahogany charging tile. This price point puts it in the luxury category, but consider that other premium Japanese chef's knives can cost just as much, and they don't vibrate!
