Inventor of $399 Vibrating Chef’s Knife Says It Requires ‘50% Less Force to Cut’

If you’ve ever looked down at a humble chef’s knife and wondered why there wasn’t more vibration, the tide is turning. Seattle Ultrasonics just dropped the C-200 and says it’s the world’s first ultrasonic chef’s knife made for the average at-home cook

With the push of a button, the $399 rechargeable knife buzzes more than 40,000 times per second, which, according to the brand, results in less friction, smoother cuts and 50% less force needed to make them.
