how do you sharpen it?




I use a knock-off of the edgepro I got for $30 online, with a nice set of compatible whetstones that click into the assembly that were $20 online. I did what everyone else does and hotglued some magnets underneath the piece you hold the knife on.

I tried a compatible strop that clicks in but it's not worth it imo; just use a normal strop.


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

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.


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


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.


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.


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.

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.

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.


Is it worth the cleaning hassle? I often avoid using a mandolin or food processor just because cleaning my knife is so much easier.

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


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.


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


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

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.

microwaves are useless because they can't toast bread no matter how hard I mash the keypad

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

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

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

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)

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 my case I just wait for the sharpening knife guy who pass once a week in my neighborhood. It is quite easy as I am working from home and he plays those distinctive panpipes notes.

That definitely sounds like Mexico.

This happens in Italy aswell.

and Spain

And China

And India. Although here they do a horrible job of it, so I prefer to sharpen them myself.

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.

Making the edge is sharpening. Removing the ripples in it is honing.

This is the first time I've heard someone say honing is very important, when I was first learning this, I was told that it was the next thing to pseudoscience!

Absolutely not. A blade can stay sharp for a much longer period of time than it can stay honed. The edge of a piece of paper is extremely sharp, but it only cuts you in specific circumstances due to being difficult to maintain a firm edge.

A knife's edge is closer to that than you'd think. At the scales of sharpness of a good knife, it's impossible to keep the edge straight for very long. A honing rod quickly brings these back in line. I hone knives after maybe a week of use; it only takes a few seconds.

And this is a comically easy property to test. Use a "dull" knife then hone it and try again. It will cut drastically better.


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

Carefully? Professionally? Except which knife stall at which farmers market wants the job?

Learning to sharpen the (correct) knife (for the task) will do as much or more for the chef who struggles here.

Prepping 1000 lemons? An ultrasonic knife is not your answer.
