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.
So you’re saying it’s ideal for murder because it brings home less damning evidence?
vibrates
oh no. OH NO!
If all it does is vibrate why does it need a firmware update?
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.
I don't think that actually answers OP's question. If all it does is vibrate then it doesn't need any software. It presumably just has a single button that turns vibration on/off and maybe cycles through vibration levels. A dumb circuit without even a single chip in it could do that.
Ah, but what if you want it to vibrate to the beat of your favorite song? Did you think about that?
How would it vibrate without wpa3 support?
Don't you think it would vastly improve your stabbing experience if the knife could vibrate the Halloween theme while you're at it?
I’d want it to whistle a spooky tune like a theremin.
To show you ads, of course. Duh.
Microphone was a little muffled, fw update supposed to clear that up.
Different frequency and patterns provide different results.
And some of those frequencies need to be paywalled, for the customer's enjoyment.
Motor with an eccentric shaft?
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?
Vibrating blade that cuts better? Why do I hear Rules of Nature playing in the background
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.
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.
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.
I doubt the vibrations would do anything to make it cut better, but to make things not stick you could also just put little dimples on the side like those of a santoku knife. So goofy.
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 (cheap) 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 much less then 0.3mm and the edge obviously tapers.
I mean, it's always worth having a couple of weird Bluetooth devices hanging around to hide passwords on when crossing borders.
I thought it had peaked when I had to put a hacked firmware onto my soldering iron
Huh, my soldering iron doesn’t even have an on switch, just “plugged in” or “not plugged in”. I’m not saying everything needs to be that simple but we sure do overcomplicate things in our devices.
