          They haven’t had the option until now so that’s trivially true. This is among the first times this tech has been put into a hand-held knife. Until now it’s been limited to industrial food processing where you’re cutting something sticky. Turns out you can prevent sticking just by vibrating the blade at a few khz. No chemical coatings required.

          I don’t expect wide adoption among chefs and this won’t at any point replace a substantial proportion of normal knives. And this implementation of the tech is silly and bears all the flaws of modern product design. But it is cool tech.

      I’m convinced that much of, if not most of, society sees technology in our personal lives as a way to (ideally) not have to learn anything or put in one bit of extra effort.

      I’ve been getting my hands dirty and doing more things myself over the past few years, and ya know sometimes the journey is more impactful on you as a person than the destination is. Learning things and interacting with the world around you is good.

      This knife is expensive, but actually pretty badass. It’s an ultrasonic frequency knife and the only non commercial use chefs knife I know of that does it and works. It cuts with no effort, but really the biggest perk is that absolute fuck all will even try and stick to the side of the blade. Still to richy rich for the benefits, but it is cool tech.

    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.

        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.

            I’m just guessing here, but it’s probably for battery management and wireless charging, which are tricky problems you’re not gonna solve with a 555. I generally trust EEs to not put MCUs where they aren’t needed, so this must have been the cheapest/easiest option.

              As i said in my original post, “A dumb circuit without even a single chip in it could do that.” Vibration units can literally just respond to voltage. It’s how electrical devices worked before chips, like old pinball machines and old radios. It works just like how a standing fan works - there’s a mechanical motor, and you literally just need to attach plain copper wires onto the motor’s contact points and stick the other ends of the wire into the slots of a wall power outlet.

              You don’t need a chip in a vibration circuit. Hell a potentiometer is more than sufficient to give you different levels of vibration

                I don’t know why I’m replying this deep to play devils advocate for some stupid knife, but I could see a situation where you haven’t completed the research on optimal frequency and ship it out while that’s ongoing. Maybe the window of optimal frequency is narrow enough, or unknown enough, that it’d be difficult to calibrate a potentiometer such that the end user could find that ideal point.

        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.)

      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 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.

      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.

          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.

      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.

        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.

        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.

      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.
