World's first ultrasonic knife vibrates 40,000 times per second

"However, at the press of a button, the blade begins to vibrate rapidly - more than 40,000 times per second - using ultrasonic energy. This reduces friction, allowing for a smoother chopping experience that requires 50 per cent less force. 'The C-200 does things no other knife can,' said Scott Heimendinger, founder of Seattle Ultrasonics. Unsuprisingly, the high-tech knife comes with an eye-watering price tag - with budding chefs facing a $399/£292 bill to up their chopping game!"

"Mr Heimendinger, who has a background in software development, spent six years crafting the C-200. 'I've seen firsthand how industrial ultrasonic technology makes clean, effortless cuts,' he explained. 'I asked myself, "Could I fit that technology into a chef's knife?' 'After years of research, development, and more than a few setbacks, the answer is yes.' The knife's blade oscillates microscopically (about 10-20-micron stroke length) at over 40,000 times per second."

"The blade itself is eight inches (200mm) long, and made from high-quality Japanese AUS-10 san mai steel stainless steel. According to Seattle Ultrasonics, the blade is 'durable, corrosion-resistant, and easy to maintain,' and can be re-sharpened just like a traditional knife. The knife has a removable battery pack, and enough power for around 20 minutes of non-stop use - plenty of time to chop up the veggies for your dinner. Footage shared by the company shows the ultrasonic blade being used to slice through tomatoes"

The C-200 is an ultrasonic chef's knife whose blade oscillates microscopically (about 10–20 micron stroke) at over 40,000 times per second to reduce friction and require roughly 50% less chopping force. The eight-inch blade uses high-quality Japanese AUS-10 san mai stainless steel and can be re-sharpened like a traditional knife. Vibrations are isolated to the blade so the handle remains steady. The knife includes a removable battery providing about 20 minutes of continuous use. Development took six years by an inventor with a software background, and the knife retails for $399/£292.
