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.

I used to sharpen my straight-knife planer blades, planing irons, chisels, and knives with whetstones / water stones. It was too big of a pain in the ass over time, so I switched to diamond stones.

Biggest advantages is that you don't need to pre-soak them and diamond stones don't develop a valley / have to be flattened.

if you plan on getting into sharpening I would just start with a coarse, fine, and extra fine diamond stone and a leather strop w/ stropping compound.

Same advice - don't use the soaking stones. Nowadays they are plenty of decent quality diamond stones (or ceramic ones)

They're really not. All you need is an angle guide you stick to the knife. Something like https://setamono.co.za/products/knife-sharpening-angle-retai...

With that all you need to do is pretty much go back and forth. Note that the whetstone eventually wears them out too.

Something to grab while you're at it, is a truing stone to take care of the whetstone as it _will_ wear out unevenly making the sharpening a pain.

Thats 2-3 extras over rolling sharpeners

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).

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 problem. Potatoes in particular stick to the blade like a strong magnet and it takes me 5x longer to prep. I enjoy cooking but not chopping endless veggies and i'm hoping this thing can carry some of that weight without looking like i'm using an oversized electric toothbrush.

You're right that's a hobby. But the hobby's definition of "proper maintenance" and what it "requires" is basically just people nerding out about things that don't matter the slightest in the real world.

To maintain a kitchen knife so that it cuts a tomato without squishing it, you don't need a book on knife science. Further, that nerdery is probably actively harmful, because instead of simple solutions, people are told they need an inspection microscope and a variety of jigs and other implements. So they buy an objectively bad electric sharpener and move on.

Also: use serrated knives for tomatoes. They don't squish.

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.

Re:Seattle Ultrasonics: Ultrasonic Chef's Knife by appcustodian2 on Saturday September 20, 2025 @04:58PM (#45317453)
Yes as I mentioned I use often-recommended knives (victorinox, shun) and have them occasionally sharpened professionally and at least in my case the ultrasonic knife appears to solve some very real problems that knife maintenance cannot.

it takes no skill to make a blunt knife sharper. To make a sharp knife sharper, sure, but in a good vast majority of home knife situations, just doing anything with any flat sharpening surface is an improvement.

I can attest to this as I have improved knifes day one of trying despite my lack of any sort of skill

Re:Seattle Ultrasonics: Ultrasonic Chef's Knife by rcpt on Saturday September 20, 2025 @06:34PM (#45318212)
I decided it was hard and never got very good at sharpening. Now I've got a Chef's Choice XV and my knives are sharper than they've ever been.
Re:Seattle Ultrasonics: Ultrasonic Chef's Knife by ripley12 on Saturday September 20, 2025 @05:03PM (#45317508)
Sharpening a knife to r/sharpening standards is hard. But just honing frequently and occasionally using a cheap sharpener will get you further than 95% of home chefs.
Re:Seattle Ultrasonics: Ultrasonic Chef's Knife by asah on Saturday September 20, 2025 @05:04PM (#45317528)
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.

Re:Seattle Ultrasonics: Ultrasonic Chef's Knife by ricardobeat on Saturday September 20, 2025 @06:09PM (#45318043)
Is it worth the cleaning hassle? I often avoid using a mandolin or food processor just because cleaning my knife is so much easier.
Re:Seattle Ultrasonics: Ultrasonic Chef's Knife by its-summertime on Saturday September 20, 2025 @07:23PM (#45318516)
for firm things its fine, clean the moment the work is done and it shouldn't be much effort, and having nice consistent slices feels good too

For anything other than ideally firm things, the cleanup can be a nightmare

Re:Seattle Ultrasonics: Ultrasonic Chef's Knife by peteforde on Saturday September 20, 2025 @10:32PM (#45319514)
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.

Re:Seattle Ultrasonics: Ultrasonic Chef's Knife by cyberax on Saturday September 20, 2025 @09:33PM (#45319238)
You need one diamond two-sided plate, holder for it, and a stropping leather. All of that can be bought for $60 on Amazon.

This is enough to get your knives to be sharp enough to shave hair.

Time investment is more individual. It took me about 3 hours to get good enough.

Re:Seattle Ultrasonics: Ultrasonic Chef's Knife by xandrius on Sunday September 21, 2025 @06:49AM (#45321627)
Is 10min per knife every 3-6 months a hobby?

Because that is just general maintenance to me.

If you don't put your good knives in the dishwasher and wash/dry them right after usage, they'll last a long time.

Re:Seattle Ultrasonics: Ultrasonic Chef's Knife by Ertuit on Saturday September 20, 2025 @04:23PM (#45317093)
Yes, and a pass with a honing steel every day to maintain the cutting edge between proper whetstones sharpening every few months.
Re:Seattle Ultrasonics: Ultrasonic Chef's Knife by kminehart on Saturday September 20, 2025 @04:44PM (#45317328)
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

Ceramic honing rod. Works amazingly well and is appropriate for japanese knives.

just a guy abusing his knife to prove he can't fix it using the wrong tool badly
Re:Seattle Ultrasonics: Ultrasonic Chef's Knife by Hikikomori on Sunday September 21, 2025 @07:59AM (#45321964)
No? The point was to understand what the tool does and when it can help. And he found out that if you have a Burr it can help. But if you have a properly sharpened knife without a Burr it won't do anything to help and will just destroy your edge.

do not buy those garbage amazon whetstones. Buy a diamond sharpening 'stone'.
