If this were made in a way you could attach to any knife, I think it'd be cool. Sharpen your knife and add this module. I'm certain it's instead made to not detach, and you can only get the blade from them. If you sharpen it, you'll have to buy a new one from them at full price eventually. If they stop existing, it's just a dead product.
Unfortunately because of how ultrasonic transducers work you need an extremely rigid connection between it and the blade - otherwise it's like having a spring between the two and it completely negates the benefits of being ultrasonic. The easiest way to get that connection is just to weld the blade directly to the transducer. In a consumer application like this, where you're compromising on basically every aspect in order to fit the form-factor, the losses from a swappable blade would almost entirely negate the benefits of the system.
In short, to have even the moderately functional product they've got, there's no way for them to have swappable blades. The system just won't be powerful enough to compensate for the losses.
If you're applying force downward, you're not using the knife right anyway.
I mean there are some situations where you want to chop, but for that you want a knife with a different shape than this. A straight, flat edge that's full length can be in full contact with the board at one time.
The shape of knife in the picture is for slicing. Light downward pressure while pulling smoothly backwards. If you do it right, you should be able to slice a tomato without smashing it.
I get that this thing has electronics in it to allow ultrasonic vibration, but WHY does that need firmware updates?
Oh look my knife got an update, now it vibrates 5.2% faster!
The vibrator knife combo is such a stupid fucking idea, just buy a really nice knife that doesn’t let food stick and sharpen it often. It would be cheaper and far easier than this garbage
Sure, but then how would I get my "personalised experience" while dicing onions? What about the assistant using cutting edge AI technology to tell me how to chop the carrots?
A battery-powered electric knife (itself not a bad evolution of an existing technology) that provides the manufacturers with the options of remote bricking, subscription and forced obsolescence. The future suuuuucks.
Frequent users don't have to worry though, we'll also offer subscription based plans. Just chose the plan that suits you the most. Even the free plan might cover your needs. It includes on stab and one cut.
This is the most common handheld style, there's all kinds of different blade shapes depending on application (god this company has poisoned the search results. SEO is a plague...)

Okay? Kinda hostile take for a stupid consumer product. It's literally just a transducer with a base station instead of a battery, that's the only difference besides a flashy case.
So it is doubling down when you're proven wrong that gives you a pants tent or is it moving the goalposts that gets you going? Can't really tell between your two replies
not interested in arguing like that other person but I'm guessing they're saying it's the first ultrasonic knife in the form factor of a chef's knife. same results sure but I don't think there's a home cook in the world (okay maybe one or two...) who would decide that whole contraption is worth their counter space, whereas all contained like that there are probably some people who want it

It vibrates at an ultrasonic resonance so you can cut a whopping 50% lighter.
I bought one to keep in my Tesla Truck full of Ouya consoles.
Ya know what else helps? Sharpening the blade
Seriously, just get a decent quality chef knife and stones to sharpen with.
But, imagine if that knife also vibrated at an ultrasonic resonance!

What anouy a vibrating sharpener? Then you can have mamy easily sharpened blades?
Does the handle part vibrate too? Asking for a friend.
Your friend should just buy a vibrator. Or 50 at the price of this knife.
Your friend is a pervert. I like them.
Anything's more fun with a knife involved.
Instructions unclear. Oh no.
It doesn't :(
Help, I can't figure out what this is meant to say
50% less Newtons of force applied downwards as you cut through your food

Whoa, deep cut
Like the knife
wow for $400 you can buy 4-5 really good knives, the kind that will easily cut your hand if you are not careful when cleaning it.
* compared to a hammer
Can you feel it in your bones as you use it?
I will never know
Between the knife and expensive laptop I think whoever took the pic should invest in some common sense classes instead.
That guy is a tech reviewer on YouTube, it probably makes for good content, and he may not have even bought it.
So he's not only got no sense he's a douche too. Thanks for the community notes on that one.
When a hater essentially self burns.

It could brick when you cut cheddar.

Yeah but then you wouldn't be using technology from Star Wars spinoffs
feel like that’s a bit different since one’s a weapon in a space opera fantasy series and this is an irl cooking cutting knife x)

Heheheh cutting edge 🥁🥁💥

You can't reason someone out of a position they didn't reason themselves into.
It sends data to Google about how many onions you slice. Also about your political views and your family...

A fool and their money are soon parted. No doubt the worst $400 knife you can buy.
Not even close.

I see serrations/combo blades on a knife and I just want to vomit.
I meant chef's knife but didn't specify. When you include mall ninja shit all bets are off.
Doing a very quick search on this and it looks like the firmware updater uses webbluetooth. This knife has bluetooth hardware in it.
Ultrasonic knives have been a thing in commercial kitchens for decades, I wonder where they get off claiming to be the worlds first US chef's knife...
Gotta link?
Quinn isn't particularly smart but my search engine nor is Wikipedia proving him wrong
This is the most common handheld style, there's all kinds of different blade shapes depending on application (god this company has poisoned the search results. SEO is a plague...) https://www.knmsonic.com/handheld-ultrasonic-food-cutter/
OK that's an ultrsonic knife, I'll trust that's it's two decades old but I'll argue that it's not even in the same ballpark as Quinn's knife
Okay? Kinda hostile take for a stupid consumer product. It's literally just a transducer with a base station instead of a battery, that's the only difference besides a flashy case.
They're all unnessary/stupid consumer products, if they give you a pants tent I'm good.with either

Unauthorized Bread (knife)
I don't think anyone has called Quinn smart
I hope he paid the subscription fee for the knife as well.
Vibroblades?! In this economy?!
Metal gear is closer each day.
