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

Yeah but then you wouldn't be using technology from Star Wars spinoffs

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.

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

[–] Hupf@feddit.org 2 points 1 hour ago

Instructions unclear. Oh no.

[–] BigBrownDog@lemmy.world 2 points 2 hours ago (1 children)

Your friend skills just but a vibrator. Or 50 at the price of this knife.

Your friend is a pervert. I like them.

[–] luciferofastora@feddit.org 1 points 24 minutes ago

Anything's more fun with a knife involved.

[–] dance_ninja@lemmy.world 5 points 3 hours ago

Ouya

Whoa, deep cut

[–] usualsuspect191@lemmy.ca 6 points 3 hours ago (1 children)

so you can cut a whopping 50% lighter

Help, I can't figure out what this is meant to say

[–] BigBrownDog@lemmy.world 5 points 3 hours ago (1 children)

50% less Newtons of force applied downwards as you cut through your food

[–] wonderingwanderer@sopuli.xyz 2 points 1 hour ago

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.

Can you feel it in your bones as you use it?

[–] BigBrownDog@lemmy.world 2 points 3 hours ago

I will never know

Ya know what else helps? Sharpening the blade

[–] Cethin@lemmy.zip 2 points 2 hours ago* (last edited 2 hours ago) (1 children)

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.

[–] Warl0k3@lemmy.world 4 points 1 hour ago* (last edited 1 hour ago)

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.

[–] FartMaster69@lemmy.dbzer0.com 14 points 6 hours ago (1 children)

Seriously, just get a decent quality chef knife and stones to sharpen with.

[–] DarrinBrunner@lemmy.world 10 points 6 hours ago

But, imagine if that knife also vibrated at an ultrasonic resonance!

[–] RamenJunkie@midwest.social 1 points 5 hours ago

What anouy a vibrating sharpener? Then you can have mamy easily sharpened blades?

50% lighter

* compared to a hammer

[–] roofuskit@lemmy.world 10 points 5 hours ago

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

[–] db2@lemmy.world 36 points 7 hours ago (1 children)

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

[–] SteveTech@aussie.zone 13 points 5 hours ago (1 children)

That guy is a tech reviewer on YouTube, it probably makes for good content, and he may not have even bought it.

[–] db2@lemmy.world 1 points 5 hours ago

So he's not only got no sense he's a douche too. Thanks for the community notes on that one.

[–] tacosanonymous@mander.xyz 6 points 5 hours ago

Vibroblades?! In this economy?!

[–] einkorn@feddit.org 15 points 7 hours ago* (last edited 7 hours ago) (1 children)

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.

[–] roofuskit@lemmy.world 5 points 5 hours ago

You can't reason someone out of a position they didn't reason themselves into.

[–] Warl0k3@lemmy.world 7 points 6 hours ago (1 children)

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...

[–] Eat_Your_Paisley@lemmy.world 4 points 6 hours ago (1 children)

Gotta link?

Quinn isn't particularly smart but my search engine nor is Wikipedia proving him wrong

[–] Warl0k3@lemmy.world 3 points 3 hours ago (1 children)

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/

[–] Eat_Your_Paisley@lemmy.world 0 points 3 hours ago (1 children)

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

[–] Warl0k3@lemmy.world 1 points 3 hours ago* (last edited 3 hours ago) (1 children)

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.

[–] Eat_Your_Paisley@lemmy.world 1 points 2 hours ago

They're all unnessary/stupid consumer products, if they give you a pants tent I'm good.with either

[–] TootSweet@lemmy.world 7 points 7 hours ago
[–] Eat_Your_Paisley@lemmy.world 4 points 7 hours ago

I don't think anyone has called Quinn smart

[–] ArgentRaven@lemmy.world 2 points 7 hours ago

I hope he paid the subscription fee for the knife as well.
