> when was the last time someone tried to re-invent something as basic as a knife? A year ago? This one is designed for woodworkers. https://www.bourbonmoth.com/shop/p/the-bourbon-blade-origina...

I thought I recognised the name - Bourbon Moth is the guy who faked a video of oily rags self-igniting to make a video to advertise fireproof bins for woodworking. This one: https://m.youtube.com/watch?v=3Gqi2cNCKQY Debunking: https://m.youtube.com/watch?v=GEtU3bYyCtA

Never heard of either of these Youtubers but I've seen tons of cans of stains and such with warnings about potential self-ignition if left on rags in the wrong conditions...

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 was surprised by that too. The Shun did surprisingly well in the real world test despite lower scores on the other two categories.

While I think this is neat, I doubt the added complexity of the device, extra space required for storage of charger and the chore of charging it are worth the benefit of a slightly better, easier slice. Might be nice for people with certain disabilities though.

If it works at least as well as the current electric knives, it let's you cut things you'd usually not try to cut. Thin slicing frozen meat for instance, carving pumpkins, cutting bones etc.

It certainly would be nice to have three or four independent reviews from people with knife skills.

If it helps, the inventor worked at other kitchen product companies like Sansaire (founder) and Anova. And at other places in the cooking world. So they’re not entirely unknown either.

The parent comment asked for a second opinion, that's not even related.

This 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.

Whetstones, pretty cheap only and not as hard as it seems.

Wet stones are hard. Rolling ones are easy albeit “real” knife aficionados don’t like it.

Whetstones were hard 20 years ago. Right now there is abundance of quality info and products. The community actually figured out idiotproof and effective ways to deburr, to strop, resin bound diamond stones are affordable (or even cheap if you just buy the abrasive from China and go the diy route).

In particular, you don't need expensive stones, guides or lapping systems to do it. An aliexpress-grade 3000/8000 waterstone, a flattening stone and a strop will get most knives shaving the hairs off your arm for under £20 all-in.

The odds I will ever learn to use a waterstone or strop are nil. A Chef’s Choice manual sharpener is really easy and makes my knives plenty sharp enough to cut tomatoes.

I'd very strongly recommend vs the waterstone. Use a ceramic or diamond one. The strop is not required but it's nice.

Sharpening knives is quite the therapeutic process, at least it was for me when I learned to do them. Now I can sharpen knives at the bottom of a tea cup or even a brick.

how do you sharpen it?

AUS-10 steel is fairly easy to sharpen, so stones are a good option but I prefer diamond sharpeners myself.

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…

> 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.

Properly maintaining a knife does. Most people don't need to properly maintain a knife. You can do it good enough with a honing steel and some crappy automatic sharpener.

I enjoy cooking good food for my family and myself, but cooking is not a hobby of mine. So if my knife can slice a tomato without crushing it, then that's good enough for me. I don't need to shave a tomato so thin that the slice is transparent.

Does the crappy automatic sharpener work? Well the knife cuts better after I use it, so yes, it does.
