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.
DarrinBrunner@lemmy.world · 21 pts · 103d
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.
