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.
It's a good idea, but it's probably cheaper and, from an ecological standpoint better (than e-waste) to sharpen knives; a top-quality professional electric knife sharpener will set you back $170 and last you a lifetime; which is a third of the cost of the Ultrasonic's knife. Cool idea though.
@Scott How much faster will the cutting board (wood & plastic) degrade? Do you recommend one over the other for this knife? Will you be making one best suited for this knife?
