I personally watched Scott spend years working on the project and obsessively iterating on the steel, the vibration pattern, the circuitry, the handle, and the form factor. Scott is a hacker, one of us for sure. I mean, the guy built a custom robot just to measure cutting efficiency...

The knife is amazing and exactly as shown in the video. Rand Fishkin has a nice short on LinkedIn trying out the knife too. I think he shows one his (sharp) kitchen knives slicing through a lemon, then the Ultrasonic. It's astounding.

Disclaimer: I am a (tiny) angel investor in Seattle Ultrasonics.

Does that video show him doing actual prep? I 100% believe he made a knife that can make a paper-thin slice of a lemon. But that's not what a chef's knife is for. As someone who thinks the world would be a better place if this product worked and was successful: for god's sake record someone processing an onion. That's what matters.

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.

Do you know if the knife still acts "sharp" when the physical blade is dull or does it still need regular sharpening like a normal knife?

Rank Fishkin from MOZ? Why is he testing knives on LinkedIn?
