First Ultrasonic Chef's Knife Vibrates 40,000X/Second for Easy Cutting

Hm usually ultrasonic cutting tools have small, disposable blades, which are tuned so that they vibrate right. Also they can produce an intense burning sensation in either the hand you're using (if you hold wrong / too tight) or in your off-hand (if you hit something hard, like a bone, which can pick up the vibrations).
I'm sure there's an ultrasonic transducer in there but I wonder how a 40w transducer (this is typical power for hand-held) can move such a giant blade around at 40khz. It does not seem physically plausible to me.

I have used this knife, I am an angel investor in Scott's company. The thing is legit amazing. He labored for years to bring this to market and it shows.

This is a really cool idea. I'm not sure I cook enough to need/afford it, but I SO want to try it out!

I wonder how well it works after the typical home user has blunted the edge, hacking at bones on tile or glass cutting boards.
