30,000 Vibrations Per Second: How Seattle Ultrasonics C-200 Redefines Cooking at CES 2026

It looks like a high-end chef's knife, but it buzzes like a piece of future tech. At CES 2026, Seattle Ultrasonics unveiled the C-200 UltraSonic Chef's Knife, a tool that brings industrial cutting precision to the home kitchen. While it handles like a standard blade, its hidden technology promises an effortless slicing experience that traditional steel simply can't match.

The Tech Behind Seattle Ultrasonics C-200 at CES 2026

The C-200 features an 8-inch Japanese steel blade that vibrates 30,000 times per second. According to company representatives, the blade only moves a distance of 10 to 20 microns—roughly a quarter the width of a grain of salt. This high-frequency vibration allows the knife to glide through delicate foods like tomatoes without crushing them and prevents crumbs from sticking to the surface.

• Durability: IP65-rated for water resistance, suitable for hand-washing.
• Battery: Removable and rechargeable via USB-C.
• Engineering: A folded circuit board design keeps the handle compact.

Pricing and Market Availability

Six years in the making, the C-200 is the first ultrasonic knife designed specifically for home use. It retails for $399 alone, or $499 when bundled with a wireless mahogany charging tile. With the first production run already sold out, the second batch is slated for a March 2026 release, targeting serious home chefs willing to invest in premium tools.
