Ultrasonic knife is the coolest tech you will see all day

I was not sure what to think when this video crossed my Facebook feed. My first thought when seeing a knife that requires an external power source to operate was that it was a solution in search of a problem. I know electric carving-knives are a thing, but they are fairly crappy in my opinion.

This thing on the other hand is incredible.

A little digging and I discovered that there were practical applications after all. Who knew?


Ramp the technology up another level and you get this industrial foodservice application as well. I could watch this for hours.


I think I will go make a sandwich the old fashioned way now. Maybe even cut it with my Carter.

    Electric knives are great to cut the foam in your gun case

    Where would one purchase this, and for how much? There is no product info in the vid.

    I always wondered how they did that. Thanks
