Don't buy dumb electronic kitchen gadgets. Get a good steel knife, learn how to sharpen it properly, and you're set for life.

Maybe it’s dumb. But the video seems convincing. Ultrasonic knives are also used in some industrial and medical settings. So the concept does work. And the inventor of this one worked at Sansaire, Anova, and other kitchen hardware places. So they have a lot of credibility producing real products.

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.

There must be a limit though. Surely a light saber is not more safe than a dull knife.

Not really. The dangerous aspect of a knife is when it moves unexpectedly. The sharper it is, the harder it is to create a scenario where it jumps on something particularly dense, like when a saw hits a knot in a tree.

If you’re pushing down with hard force, it basically doesn’t matter if the knife is sharp anymore, it’ll just chop your finger off. However, with an extremely fine cut, it will be much easier to reattach, as the edges will match up well. With a dull knife, you’re not slicing, you’re more tearing your way through something.

You say this from any special knowledge or is it just your opinion from the video? Looks to me like it will go through your flesh and bone like they're not there, in a way even a razor sharp knife won't. Also, while it's true that dull knives are in some ways more dangerous than properly maintained ones, that doesn't mean safety increases monotonically with sharpness. I sharpen my kitchen knives every weekend and I'm…

Medical bone cutting knives are ultrasonic. I assume this one has a duller edge than those though.

This is a QVC product with the name of a US tech city slapped on it.

Signed, a guy living nearby the home of QVC in a decidedly non-tech area of the US.

Ps. don’t buy future e-waste kitchen ware unless you have accessibility reasons. You can get a good-enough victoronix 8” chef knife for $65 (I paid $36 a long time ago) and a world class chef knife for less than $250.

It certainly would be nice to have three or four independent reviews from people with knife skills.

If it helps, the inventor worked at other kitchen product companies like Sansaire (founder) and Anova. And at other places in the cooking world. So they’re not entirely unknown either.

> when was the last time someone tried to re-invent something as basic as a knife? A year ago? This one is designed for woodworkers. https://www.bourbonmoth.com/shop/p/the-bourbon-blade-origina...

I thought I recognised the name - Bourbon Moth is the guy who faked a video of oily rags self-igniting to make a video to advertise fireproof bins for woodworking. This one: https://m.youtube.com/watch?v=3Gqi2cNCKQY Debunking: https://m.youtube.com/watch?v=GEtU3bYyCtA

It's interesting that AvE devoted multiple videos to debunking oily rags but believes 9/11 was an inside job.
