CES 2026: This knife secretly vibrates whenever you minimize with it

I spent a part of my Sunday evening at CES 2026 chopping greens on the showroom flooring of the Unveiled media occasion. However this wasn’t your common cooking demo: My knife vibrated at any time when I minimize right into a tomato.

This would possibly sound like some form of twisted Cutthroat Kitchen problem, however belief me — it is extra sensible than it sounds. Launching this month from the cutlery startup Seattle Ultrasonics, the C-200 UltraSonic Chef’s Knife has an orange button on its deal with that makes its eight-inch Japanese metal blade vibrate about 30,000 occasions per second. This enables it to slice by meals extra easily than a daily knife, in addition to prevents crumbs from clinging to the blade. It additionally should not have to be sharpened as ceaselessly.

Impressively, the C-200 solely wiggles a distance of 10 to twenty microns when it vibrates — 1 / 4 of the width of a grain of salt, per a PR rep — so you do not see or really feel it transfer in any respect. It seems and handles like a normal chef’s knife, albeit one on the heftier aspect. The one purpose I am assured that Seattle Ultrasonics wasn’t punking me with a daily knife is as a result of it sometimes made a pointy pinging noise if it was used whereas moist. It is the identical high-pitched sound {that a} wine glass makes in the event you run a moist finger round its rim.

I would not say the C-200 labored dramatically higher than the great new chef’s knife I simply received for Christmas, however it definitely sliced like a dream. I had no bother getting it to chop paper-thin items of tomato with a lightweight contact. Seattle Ultrasonics’ rep likened it to using a motorbike versus pedaling an e-bike in that it makes your expertise extra easy.

The C-200 has been six years within the making, and the corporate claims it is the primary ultrasonic knife available on the market that is meant for house use. Industrial choices are costly and ponderous; the smallest various is the dimensions of a shoebox. To maintain the C-200 small, its circuit board needed to be folded on itself throughout the deal with.

The C-200 is IP65-rated for water resistance, that means you’ll be able to hand-wash it like some other chef’s knife. Its detachable battery is rechargeable through USB-C.

The C-200’s first sold-out manufacturing run begins delivery later this month, and its second batch of reservations is now reside on the Seattle Ultrasonics web site forward of a March launch. It retails for $399 by itself and $499 with its wi-fi mahogany charging tile, so it is decidedly a splurge for severe house cooks. In its protection, different premium Japanese chef’s knives value that a lot and do not vibrate.
