The only actual benefit I find it has over a well-maintained sharp chef knife is the non-stick aspect, which looks really nice but not $300 nice IMO.

Most people don't sharpen their knives enough and therefore they have to expend a lot of effort to sharpen them.

If your knife is only slightly dull it takes 10 seconds to resharpen it, unlike if you've gotten the edge all folded over and such.

Elsewhere 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…

I can see why one would use a serrated knife to cut bread, but what knife would one use to cut cheese other than a chef's knife?

Jacques Pépin suggested at [0] "basically you need three knives":

  - a chopping knive, 9-12" depending on one's hand
  - a utility knife for slicing, about 6"
  - a paring knife, a cheaper ordinary one is fine
Of those, other than the chopping/chef's knife, I imagine that one could generally slice cheese with the utility knife (depending on the cheese, of course).

Yes, and a pass with a honing steel every day to maintain the cutting edge between proper whetstones sharpening every few months.

don't use honing steel. at best it doesn't do anything, at worst it damages your knife. here's a closer look at it with a microscope. https://www.youtube.com/watch?v=Y4ReQ83CZOQ

just a guy abusing his knife to prove he can't fix it using the wrong tool badly

I'm a bit surprised to see how much snark there is in the comment sections of this video. The requests for "let's see an independent chef use this knife to do real kitchen work" make total sense, but the moralizing around e-waste and losing fingers etc feels off balance. People spend hundreds of dollars and many hours sharpening kitchen knives, of course there's a viable market for sharper kitchen knives. And for e-w…

E-waste can be solved without reducing the number of items. Just requires basic investments in recycling.

This episode of the Search Engine podcast goes into detail about that: * https://podcasts.apple.com/us/podcast/the-puzzle-of-the-all-...

Did you mean the Search Engine podcast..?

I did. Thanks for the correction.

Does that video show him doing actual prep? I 100% believe he made a knife that can make a paper-thin slice of a lemon. But that's not what a chef's knife is for. As someone who thinks the world would be a better place if this product worked and was successful: for god's sake record someone processing an onion. That's what matters.

In Rand's video he does an "old" lime, mozzarella, and a shallot. It's just a quick vid he did in like five minutes but it shows some prep. Rand is a prolific amateur chef... https://www.linkedin.com/feed/update/urn:li:activity:7374472... Disclaimer: I've enjoyed many delicious meals at Rand's table

If thats the actual best demonstration thats not good at all. Like either he is the worst cook ever or the knife is actually difficult to go down straight with..

Damn, I was set to completely dismiss this as entirely useless overcomplication but making stuff not stick to the knife would be nice.

That’s where a lot of mess comes from, so I’m very interested in this tech. The worst are cucumbers, they stick to the blade and new slices pop them up and they roll everywhere. I get some better results by slightly angling the blade but it’s not perfect. The blade quality doesn’t look great but I think any decent cook that knows how to hone will do just fine with it. I’m not sure I’d spend the money and replace my e…

Maybe instead of building it into the knife, it needs to be something you could attach to any knife

just want to point out that maintaining a knife is a whole hobby that requires a time investment of learning the skill and storage of additional tools and materials. i'm surprised at all the apparent knife enthusiast posts trashing this device. I take my victorinox (which is absolutely nothing special and surprises me that it costs $60+ dollars) to the farmers market for sharpening but sharpness isn't even the proble…

my new favorite kitchen gadget is small deli slicer, $75 on amazon. minor pain to clean, but MUCH faster than a knife, totally safe (pusher keeps fingers away from the blade) and you get precise thickness cuts every time, which means they cook precisely too. Especially good for vegetables like potatoes, onion, eggplant, etc.

I did this too! I love being able to buy a large chunk of deli meat and slice off what I need at whatever width I want.

Home cook deli slicers are the most slept on, underrated pantry upgrade.

A good quality well sharpened knife already works incredibly well, doesn't cost $500, doesn't need to be recharged, and isn't going to be e-waste in 5 years (when the battery fails). It's a cool idea, and I hope it is commercially successful, but not for me.

This thing is $399, which is on the expensive side of prestige chef knives, but by no means the extravagant side of it. People who buy knives that cost more than $150 generally buy lots of knives, and this is priced for that market.

It’s $499 with the wireless charger. I see that the charger isn’t required. You can take the battery out of the knife and charge it by USB. I would correct my comment, but it is no longer possible for me to edit it.
