I want to see what happens when it cuts your finger. Actually, I don't want to see it. But I'm curious.
There are surgical scalpels that are ultrasonic, and they are incredibly sharp when activated. They can cut through skin and tissue like butter!

#172I work with some bigger ultrasonic cutters/welders and the thing I didn't see in the video was the horrible noise they make. He says the knife makes no noise but they also don't have the noise on for the shots of the bigger ones so I'm suspicious.
Sound is on for the tomato shot in the beginning of the video, FYI. It is extremely quiet.

#173Elsewhere on the thread I pointed out that I'd noticed the video doesn't show anybody doing actual prep; making an easy but deliberate thin slice of a tomato is one thing, quickly dicing an onion or a bell pepper is a very different thing. To that observation I'd add (h/t my Slack friends) this interesting site Seattle Ultrasonics stood up: https://seattleultrasonics.com/pages/knife-database One thing I notice here i…
A talented chef might cut vegetables at 25hz, while the blade is moving at 44khz. So whatever cutting improvement is conferred by the ultrasonic tech will certainly be applied towards fast cutting. It seems that the main benefit for fast cutting would be that food doesn't stick to the blade.
I'll cut bread with my chef's knife (amazon shun knockoff) when I want to make less of a mess. One interesting thing I noticed is that when Scott was cutting bread in the video he was cutting a croissant and no crumbs fell.
It will be interesting to see the knife in the hands of real chefs. Two things I'm curious about are whether the ergonomics of the button are good, and whether the ultrasonic action atomizes foods as they're being cut, changing the experience of cooking in some way.

They actually had an industrial design studio come up with the design. It isn’t white labeled “Alibaba junk” and to my eyes, it doesn’t resemble that either. > I've got knives that I've had for over 20 years that perform as well as this thing appears to (in the slick prepared advertisement). You have knives that can not have potatoes stick without scallops in the blade? Or that can atomize lemon drops? Or that can cu…
Why on earth would I care if a potato sticks to my blade, and why would I need to atomize lemon juice with my knife?
I worked in some of the best kitchens on the planet and for every hipster with a blue paper #2 carbon steel hand made japanese chefs knife there was an old gray beard with a row of old busted victorinoxes hanging on the wall. Both of these cooks would filet a halibut beautifully.
It isn't the knife.

#175This is a QVC product with the name of a US tech city slapped on it. Signed, a guy living nearby the home of QVC in a decidedly non-tech area of the US. Ps. don’t buy future e-waste kitchen ware unless you have accessibility reasons. You can get a good-enough victoronix 8” chef knife for $65 (I paid $36 a long time ago) and a world class chef knife for less than $250.
It is only eWaste if you think our future does not resemble the Fallout games. But if you do this will be excellent tech for melee weapons.
now I want to see ultrasonic fencing

This is a semantic argument. This product smacks of being a garbage kitchen gadget. Whether or not it's a QVC product, it certainly looks like cheap white-label alibaba junk. Just look at that handle. Did they just slap a knifeblade into an electric nosehair trimmer? I'd try one out of professional/academic curiosity (I'm a chef), but am highly skeptical of this product. It looks like absolute trash. All the people s…

Have you seen this knife do any of these things in action? Will it continue to do so? Nobody has, or will, until this gadget hits the market.
I remain skeptical in spite of your weird defensive reaction. I'm speaking about how a product appears to me as a professional. Not attcking you personally (unless it's your product... then I think you should do something good for society with your time)

The guy has a YouTube video where he claims to have spent 6 years working on this product. Is he lying?
Re: Ultrasonic Chef's Knife
#178Maybe I'm just a sci-fi nerd who loves innovation, but this is so cool! Clearly, this product is not intended for the mass market, and may find purchase with people who have tennis elbow and who can afford it, etc. . But still, when was the last time someone tried to re-invent something as basic as a knife?
Me, immediately: ooh Star Wars vibroblade!

Check out Japanese knives. The Tojiro DP I got for an inflation adjusted $75 is a dramatically better knife than that Victorinox.
i've had both, and the reality is that they're both just steel -- a good grind will make any shit steel knife cut like a 700 dollar Japanese blade for a few days.
(and yes the Japanese steel dulls too. No cheating physics.)
