How does this compare to the electric carving knives?
It's ultrasonic; the frequency is much higher while the amplitude is much smaller.

#12Hard to watch the tiny video. Cannot be made full screen. Rotating phone sideways the website header obscures the video.

#13What happens when you “oops”? All the way through the bone?
Same as a really sharp knife. In general though, dull knives are more dangerous. You have to cut with more pressure and they're more likely to slip.

#14Maybe I'm just a sci-fi nerd who loves innovation, but this is so cool!
Clearly, this product is not intended for the mass market, and may find purchase with people who have tennis elbow and who can afford it, etc. . But still, when was the last time someone tried to re-invent something as basic as a knife?

#15This is the best demo video ever! Congrats on reinventing the knife!

#16Super cool! I wonder if it would bother pets

Yeah, have to say the video is pretty good. I came in expecting the typical shopping channel pitch, but it did a very good job explaining the things the knife can and can't do. It really helps that it's presented by the inventor himself.
Still won't buy one but still.

Watch the video.
It's not obvious at first in the video, but they pre-cut a flat base into the plum to stabilize it on the table, and are cutting in at a slightdownward angle. I feel like you could make nearly the same shot with a regular knife. Tricks like this (and the deliberate filming angles to obscure those details) make the video seem disingenuous and come across akin to a snakeoil sales pitch, which detracts from my genuine interest in how the ultrasonic tech fares.
The shot of the scale showing force as they cut through a tomato was more compelling. I notice after the initial breach, when the knife is about halfway through, the forces are equal again. I assume that's due (at least in part) to friction between the inside of the tomato and the wide, side of the blade. Do they make a skinnier vibro-blade, or something like an ultrasonic cheese cutting wire?

#19That looks really cool. Especially loved the wall of prototypes with raspberry picos etc.
Way outside the price range I'd consider personally but I look forward to having one in 5 years at a hopefully lower price point

#20While I think this is neat, I doubt the added complexity of the device, extra space required for storage of charger and the chore of charging it are worth the benefit of a slightly better, easier slice. Might be nice for people with certain disabilities though.
A lot of the cool stuff we have now started off for accessibility.
