This is nonsense and your cynicism is unwarranted. I personally know Scott. He's worked on food tech in Seattle for decades, and developed the product and fundraised for Seattle Ultrasonics locally.

Ultrasonic knives are historically large footprint devices used in commercial/industrial food prep. The innovation here is making ultrasonic hardware compact enough to fit in the knife handle.

Sadly Howard Schultz moved the Ultrasonics to Oklahoma City a while back.

Are you arguing that what’s good for the belt-loop is good for the hand?
