I’ve seen this knife on YouTube. It vibrate at ultrasound frequency that makes it sharper than the blade really is and the ingredients don’t stick to it, or so they claim. If it really does perform as demonstrated, it’s pretty cool, but still overpriced.

we’ve engineered the bolster connection to withstand up to 50 lbs. of pushing force, so you can chop without worry. (Our human arms could only muster 30 lbs. This is why we’re nice to the robot.)
Noodle-armed motherfuckers could only manage 30 lbs of force with their arms?
synapse1278@lemmy.world 5 days ago
Hummm ackchuly, lbs is a unit of mass, it is not used to measure force, they ackchuly mean 136N 🤓
midribbon_action@lemmy.blahaj.zone 4 days ago
Pounds is force, newtons is also force. You even converted it correctly; you wouldn’t be able to do that with like grams or any other mass unit. The only reason we use pounds and mass interchangeably is that we all experience pretty similar gravity all over the world, so a certain mass will generally exert the same amount of force regardless where it is on the Earth’s surface or what it’s made of.

Well, up to 50% less effort for that low price? Sign me the fuck up!

This is good as an accessibility device for people who have trouble doing the proper circular knife cutting motion, but if you can use the proper technique without trouble, it is not really much better or worth the cost.
WoodScientist@lemmy.world 5 days ago
I don’t see accessibility as the main benefit. I see reduced need for sharpening. Yes, you can always sharpen a knife, but it’s not as easy as people pretend. And it’s another chore you have to do.
ALoafOfBread@lemmy.ml 5 days ago
I doubt the vibrations would do anything to make it cut better, but to make thi gs not stick you could also just put little dimples on the side like tose of a santoku knife. So goofy.
NuXCOM_90Percent@lemmy.zip 5 days ago
People freak out over the dimples because it means that some day they won’t be able to sharpen the knife anymore.
Which ignores that once you are even two millimeters worn down it is probably time to get a new knife regardless due to ergonomics and the like.
And yeah. Vibrations only make sense if you are sawing through food. That is why those electric carvers are genuinely amazing and worth grabbing if you are hosting a big roasted meat party (e.g. American and probably also Canadian Thanksgiving). Non-serrated blades don’t do that. If you need to saw through your food with a chef’s knife then you should have sharpened that years ago. And if you actually CAN saw through your food with the chef’s knife, odds are the blade is so fucked up that it is not salvageable to begin with.

I got a knife my grandfather used, that has been sharpened so much it looks like a fillet knife. Ergonomics? It cuts, I don’t care. It’s a good reserve.
Good point about dimples though. But thinking about it why wouldnt I be able to sharpen it? A knife’s like 2mm thick while a dimple is idk I don’t have one such knife, but it’s probably less then 0.3mm and the edge obviously tapers.
HeyThisIsntTheYMCA@lemmy.world 5 days ago

It’s a good reserve.knife is knifeFTFY buddy
gens@programming.dev 5 days ago
Stuff sticks to knives because they are flat. They need to have dimples for stuff not to stick. Even with ultrasonic vibrations things will stick because things are elastic and sucktion.
I doubt this knife has the power for its vibrations to make a meaningfull difference in cutting.
That’s my opinion at least.
herrvogel@lemmy.world 5 days ago
Ultrasonic vibrations have been successfully used to make cutting tools more effective for a long time. It doesn’t make the cutting edge sharper or amplify the force, it just moves it back and forth slightly, in microscopic imitations of a cutting motion. That does work. Though at the end of the day it won’t magically make a dull knife sharp.
Ultrasonic vibrations have also been successfully used to get shit off of surfaces for a long time too. It is a common and effective method. Though it usually involves a bit more than just shaking the thing, but still…
Theoretically this knife could very well do both of those things. Probably not well enough to be worth 425 dollars, but probably entire useless either.
OwOarchist@pawb.social 5 days ago
Even with ultrasonic vibrations things will stick because things are elastic and sucktion.
Eh, perhaps not.
Ultrasonic vibration causes tiny cavitation bubbles to form at the interface between metal and liquid, and then those bubbles collapse a tiny second of a fraction later … quite violently. If it’s well designed, then it should clean stuff off of itself just like materials you put in an ultrasonic cleaner.
But these cavitation bubbles are strong enough to eat away at the metal itself as well. I expect this knife might not actually last very long if you use the vibration a lot.
Underwaterbob@sh.itjust.works 5 days ago
This test: www.youtube.com/shorts/PTd98UnJnnU looked fairly objective to me. It’s kinda cool, but not as impressive as most demonstrations (probably shills or “official”) make it out to be. It certainly didn’t pass through the crust of that baguette much cleaner with the vibration on.

nah. oversharpening will wear your knife to nothing in no time.
takeda@lemmy.dbzer0.com 4 days ago
Still, why does it need Bluetooth and firmware? Sounds like all it needs is just a vibrating motor.
ColeSloth@discuss.tchncs.de 5 days ago
It does work and it is super cool from any videos or info I watched on it. Because metal is flexible, the size, length, thickness, and weight of the blade all gave to be taken into account in order to get a vibrating frequency that works. If you ever watch videos of this or ones like it (this is the only good working home use kitchen knife I know if) it’s pretty bad ass, if for nothing else than just for how anti stick it is. I’m still not willing to pay like $400 for it. I’m a big knife sharpening and cooking guy, but I don’t think I’ve paid over about $50 for any of my kitchen knives or over $230 for a pocket knife. Now if I ever wound up seeing one of the Seattle ultrasonics somewhere new or used and still looking good for under $200 I’d probably break down and buy it. Blade stick is pretty annoying when you want to cut something very consistently and not spend a bunch of time to do it.
porous_grey_matter@lemmy.ml 5 days ago
if you want to cut something very consistently and not spend much time to do it you use a mandoline
ColeSloth@discuss.tchncs.de 5 days ago
Those seem fast if you don’t know how to use a knife very well. Plus then you got to clean the thing. Plus you’d be using it a long time if you were trying to make something like fries. Plus they don’t work with things like tomatoes. Then let’s see how a mandolin does with cilantro or green onions.
A mandolin is generally a tool for a novice.
porous_grey_matter@lemmy.ml 5 days ago
Disagree, I’ve worked in plenty of commercial kitchens with them and am fine at using a knife.

disorderly@lemmy.world 5 days ago
The incredibly silly true answer is that the software industry’s love for “deploy early, deploy often” has led to all embedded devices shipping with over-the-air (OTA) update support even when it barely makes sense. The earliest units of a given product run will ship with a minimally viable product build that has lots of bugs, but solid OTA.
Fun anecdote: I had a TV backlight die after about 3 years, and the root cause was a shitty embedded app that incorrectly regulated the voltage for the LED strips.
Brkdncr@lemmy.world 5 days ago
How would it vibrate without wpa3 support?
mycodesucks@lemmy.world 5 days ago
It doesn’t…
But the kind of people who are impressed by a vibrating knife are also likely to be impressed by the ability to update firmware. They don’t know what firmware DOES, they just know it’s modern.
