#272This product is a huge gimmick. Buy a $20 double sided sharpening stone on amazon and you can keep even the cheapest stainless steel knives sharp and chef ready for years. Just basic knife sharpening skills are needed which you can pick up in 10 minutes on YouTube.
Re: Ultrasonic Chef's Knife
#273I've invested close to a thousand dollars in sharpening tools over the years. I keep my knives super sharp as a hobby more than anything. I'd still love to have one of these in the drawer for certain tasks. It's ugly and clunky but I'd probably still use it on a semi-regular basis for warm breads, cheeses, etc. I bet the action would help with sharpening as well.
I do wonder if a tuning fork or 'mass on a stick' hidden in the tang could provide enough vibration to help with the sticking. You'd probably have to smack it with every cut but it's so rarely a problem that would be fine.

#274I find it funny most of these comments are about how unnecessary this thing is.
To me it has immediate appeal to make cutting easier. It's also really not that expensive. I suppose this is the same site that is crazy about AI and thought Dropbox would flop. This thing has more utility than AI to me. I suppose being a software person can warp your perception of the real world.

#275As an aside, this feels very familiar as a sci-fi weapon, does that ring a bell for anyone? I was thinking William Gibson first but I can't place it there.
This could be the exemplar prototype for Dune knives that can penetrate a Holtzman Shield. Also recall in Dune there is an aversion to technology, so the simplicity and required human operation is a perfect fit.
> in Dune there is an aversion to technology
Just computers, no? IIRC they use knives because the shields stop fast-moving objects like bullets, so you need a slow-moving object like a knife.

But I want a ultrasonic knife.
Re: Ultrasonic Chef's Knife
#277The concept of the knife is interesting. I could see myself buying one if I had that much money lying around.
Maybe if the home chef who needs a leg up sees this it would prevent them from spending that much or more on more expensive knives and maintenance products. For those of us who know our way around the kitchen I’m not sure how much benefit I would get out of it.
Also did anyone think some of the cutting segments, particularly the radish, seemed sped up? The movement of the blade and hand looked a bit unnatural.

#278I personally watched Scott spend years working on the project and obsessively iterating on the steel, the vibration pattern, the circuitry, the handle, and the form factor. Scott is a hacker, one of us for sure. I mean, the guy built a custom robot just to measure cutting efficiency...
The knife is amazing and exactly as shown in the video. Rand Fishkin has a nice short on LinkedIn trying out the knife too. I think he shows one his (sharp) kitchen knives slicing through a lemon, then the Ultrasonic. It's astounding.

Same as a really sharp knife. In general though, dull knives are more dangerous. You have to cut with more pressure and they're more likely to slip.
There must be a limit though. Surely a light saber is not more safe than a dull knife.
It's not my impression that if you make a knife very very sharp it turns in to a lightsaber.

how do you sharpen it?
Honing is 1,000x more important than sharpening. When it does come time to sharpen, I constantly see places offering knife sharpening services, and they’re usually cheap enough. Or you could get a gizmo that does a mediocre job (and shaves away far too much material) if you just want to get it done. Or you could learn to do it yourself which isn’t that hard or time-consuming but is somewhat of a labor of love.
What exactly is the difference between honing and sharpening.
