Concerns about safety aren't moralising, and this isn't just a "sharper kitchen knife". First, on sharpness, it takes me about 15 minutes once a week to sharpen my cleaver, two chef's knives, paring knife and breadknife. I could spend another half an hour or so and get them to razor sharpness, but I don't because I don't need or want that level of sharpness for kitchen work. Therefore, while something that eliminates that 15 minute task could be of value to me (though personally I rather enjoy the process), something that provides a sharper edge is not. Secondly, even if I were to use razor-sharp knives, there's a limit to the damage they will do to my hands in a typical accident. In particular, even a razor sharp knife will usually stop at the bone. I don't know if this knife will because this advert didn't address safety at all, but given ultrasonic knives are used for cleanly cutting through bones in surgery [1] it's reasonable to suspect it might not. Adding to my chef's knives the ability to smoothly pass all the way through my finger would not be an upgrade in my view [2]. Lastly, to raise questions about a product's safety is not "moralising". If I were to say that you shouldn't use this knife because of safety concerns, that could be viewed as a moral position, but I don't care about that at all. You can use chainsaws and flamethrowers in your kitchen for all I care. When I say I would be unlikely to buy this thing without some information on what it will do to my hand in the event of a kitchen accident, that's just a choice I am free to make as a consumer.

[2] As it is, I have what seems to be permanent scarring and some loss of sensation on my left thumb from cutting it to the bone with my breadknife a year ago, and my mind replays the trauma every time I pick that knife up. (No, the knife was not blunt. It was brand new at the time, and I've since maintained it to the same level of sharpness it had then, using a ceramic sharpening rod and a whetstone for the tip. The accident was due to me being distracted and positioning my hand incorrectly. And yes, better technique would have prevented it, but I'm not and never will be a trained chef. Had I used this ultrasonic knife I expect I would have taken the end of my thumb off.)
