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

    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.

    Does the handle part vibrate too? Asking for a friend.

    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.

    Between the knife and expensive laptop I think whoever took the pic should invest in some common sense classes instead.

    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

    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.

    if(payment == false) {
        blade.sharpness = 0;

        reflection.displayAdd();

        blade.sharpness = 4;
        handle.confort = 3;
    } else {

    It sends data to Google about how many onions you slice. Also about your political views and your family...

    This is one of those situations in which I want to talk some sense into people but then realize mid sentence that it's a lost cause.

    A fool and their money are soon parted. No doubt the worst $400 knife you can buy.

    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...
