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!
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.
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 :(
Whoa, deep cut
Like the knife
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
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.
* compared to a hammer
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.
Can you feel it in your bones as you use it?
I will never know
