Free idea: put this tech in a mandoline slicer.

Even the best tend to struggle with consistency and can only go so thin due to all the friction. An ultrasonic mandoline that can overcome all that would probably fly off the shelves and better match the original industrial intent.

On one hand I would buy that instantly. On the other hand, it’s already missing small pieces thanks to my current mandolin. Not sure I want to make my scariest utensil scarier.
