3D print yourself a tool to perfectly sharpen your knifes! 3 years ago my first intention with this channel was to make tech and science content but also geeky cooking videos. Well, due to time constraints I ended up only doing the first besides some sous vide cooking on live streams. In order to go back to the roots at least a little, we'll today explore my most popular Thingiverse model, the DIY knife sharpening tool for perfectly sharp blades.

First BTW!
Would it be practical to make spherical bearing able to move left - right? It could make angle even more uniform, especially at the tip.
you forgot to make sous vide steak test
The spherical bearing idea to remove sloppy movement is a good idea but, the magnetic hold isn't terribly useful as many blades use non-magnetic or poorly magnetic alloys.
Addition of either a spring clip or physical clamp would go a long way in improving functionality.
Even use of a dovetail and spring to apply pressure to the stone would be beneficial in accounting for variation in those inexpensive stones.
Wanted to watch this, but the music made me stop. Please stop adding background music.
why not stop printing and wasting all that plastic just to make more junk that will eventually end up in a landfill for a the next 9000 years
"why not print something useful for once" me: *looks at desk FULL of 3d printer tests* "umm... true"
Yup, I've mostly printed calibration cubes so far. I did design and print a holder for a roll of solder thread recently, so that's quite useful.
Lol, exactly, that flood of Benchy's struck a chord.
@@wr3921 It is satisfying to see those tolerances get into the hundredths of a millimeter though.
The second print (after a test print) on my printer was a wall mount that I designed for the shelve of my printer to make it less shaky :P
@@user-bl4oq7fd8d It's definitely important to have a stable base for your printer. I recently ordered a roll of flexible filament, gonna print some dampening cups for the feet to make it slightly less noisy.
Don't forget, you can get any blade extremely sharp regardless of its quality. The quality of the steel only dictates HOW LONG the blade will stay sharp.
Also, some steel has finer grains and will sharpen to a finer edge.
Very true!
@@TerryPullen usually cheaper knives have softer steel, harder steel makes all the difference
@@juhotuho10 No. It depends on the usage area. In the kitchen stainless knifes are prefered for easy cleaning and long lasting sharpness, the drawback of stainless steel is the difficulty to sharpen it due its hardness. For hunting knifes most prefer a softer steel with a higher carbon content. Sure, you can't soak these knives for to long or they will rust. The edge is also softer, but, they are way easier to sharpen. Meaning that standing in the woods with a simple sharpening tool and a dull knife is no problem if it's carbon steel.
yeah that's mostly true, but some cheap knives are made of really crappy steal and (like ceramic) the edge isn't strong enough to support itself while sharpening and instead of grinding it cracks at the very edge
Nonono, that idea is incomplete! You should design a knife sharpening jig that you can clamp to your 3d printer! Why move the knife back and forth by hand when you have a printer with perfectly suited stepper motors for that!
@David knives don't kill people, 3d printers kill people.
Exactly! I just spent 5 minutes re-finding this video so I could complain that it wasn't what I was hoping for. Literally, if there were a knife-sharpening app for a 3D printer, I would buy the 3D printer just for that purpose.

@@weavilemaster123321 you mean like that "tomato-remover-stabber-printer"?
I have the "edge pro apex" sharpening system, it's basically the same thing. It has a ball knob handle that I really like
Hi Steph(f?)an, I love it. A noticed that, because youre knife has a curved back, it is rocking a little against your back stop. You could fix that by having a backstop which is two posts rather than a straight edge. Just a thought.
This should work better in the latest revision model. Made the body longer and slightly adjusted the guide.
@@CNCKitchenKitchen instead of magnets. use the backstop and just tighten it down on top of the knife
Easiest way would be to add clamps on the otherside (back)
Just add a second row of magnets. Two should serfice
400/1000 grid is a good combination, but you must try 6000 after you've finished with 1000. 6000 will bring a MIRROR finish to your blade which not only feels intimidating but also makes it ultra-sharp. Believe me it's an experience you will never forget as it makes cutting pork as easy as cutting tofu.
Not all knives hold a 6000 grit edge.
Softer steels will just start to roll.
Hard Japanese knives, or super steels will be fine at 6k.
@@autumn5592you ever use a CVD Diamond Coated Steel Blade?
@@ericlotze7724 On a knife? No.
On other tooling at work, yeah.
Why do you ask?
@@autumn5592 outside of cost, would it still have the same benefits? In theory not needing to reset the edge?
(Although that study on how hair dulls razor blades meas sharpness may not be all that matters)
Low friction would be interesting too.
when sharpening, you should try going for longer strokes across the entire length of the blade instead of short saw-like movements. the latter might cause inconsistencies in the blade's curve or even a recurve section which can be very annoying when chopping (the edge doesn't touch the board perfectly and leaves a bit uncut at the bottom). Also with when you get to your fine stones, try "stropping" the knife with it. only pull back with the stone while using extremely light pressure for a couple passes on each side back and forth. this will even out the wire-edge at the end and make it sharper than the stone normally would with normal sharpening technique. Finally, I think you should spend some more time with the finer stones because the knife seems to want to snag the cutting board rather than slide across it, which is a sign of a saw-tooth-like edge. You stropped it well, so it can't be a wire edge, but rather a sawtooth edge left over from coarser stones. Either that or maybe the molybdenum-vanadium-steel alloy IKEA used is just very brittle and chiped while sharpening. I know that some cheaper, very hard and brittle steels can chip and crumble when sharpening, but this is rare.
I am so confused. Where is the part where you put it into the test rig and tell us how much force it can withstand? :p
Or... how much force it takes to slice through the tomato. Before and after sharpening.
Damn, I knew I forgot something. I'm really happy that not everyone down voted the video just because there weren't any charts and tests in this one ;-)
Since seeing this video I have printed a knife sharpener for myself. I already had one of the bought ones
which was OK but, your 3d printed version is far better and I love it. Thanks for sharing your design
Will einfach nur ein fettes Dankeschön hier lassen! Das Teil funktioniert tadellos! Ich habe bisher immer frei Hand auf Wassersteinen geschliffen, hatte aber nie ein so gutes Ergebnis wie mit diesem Jig. Einfach gut!
A man who can value a good, sharp edge is a man of culture! A man who can make a good sharp edge is a man of worth! For the humble knife is the essential tool that built civilization.
A man who can value a good sharp edge wouldn't buy crappy knives. High quality stainless steel knives are non-magnetic.
@@mdk1000 Funnily enough, i own multiple medium to high quality knives both stainless and non-stainless and all are more or less magnetic.
mdk1000 A man who can value a good sharp edge will skip the stainless steel altogether and go for high quality carbon steel.
I am just like you! My tools in work shop and kitchen are both such a pleasure when sharp and accurate, I will print your design soon!
I printed 1st version year ago, and I love it. I did not noticed it is your model.
Two half thumbs up buddy. I took up you suggestion & bought one of these knives. Within 24 hrs I had cut both of my thumbs. Without doubt the sharpest knife, I've owned for a while. Waiting for the stones to arrive & for my kitchen razor blade to dull.
Great, i started designing one of these some while ago and never finished it, now i can print this instead! :-)
Probably gonna be printing two, one for myself and one for Stockholm Makerspace.
I must thank you here, Stefan. Your Knife Sharpening Jig? AWESOME. Printed it all at the library and it really not only came out great but it also showed me many things I want out of my own future 3D Printer setup. Did it on a Makerbot and wasn't totally happy with the results but definitely gave me good information going forward about what printer I want, etc. And the jig works. WELL. Going to be adding some 5000 grit and over stones as well, soon.
I love sharpening tools/knives. So therapeutic and rewarding! This jig looks awesome!
nice to see people exploring 3d printing and finding it useful, instead of printing useless stuff
printing now and parts ordered from aliexpress thanks stepfen, also love the meltzone podcast
If you split the stone holder into two segments, you wouldn't need to look for tape to fix the size of sharpening stones, and it might allow you to use more types?
Thanks for posting this 3D printed sharpener. I'm having a go at building it - already downloaded the files and left a small tip :-)
The first time I got a kitchen knife at Ikea, my friend, at the time a materials science student, was with me. He'd done some studying of stainless steels, and he said that the steel used in the stamped knives at that time (blue and grey handles) looked really promising. They're still pretty sharp (almost 20 years later), although they could probably use some touching up.
I have two Ikea 365+ knifes, one of them is heavily abused second hand. I only sharpened it once and it's staying sharp for a very long time. X50CrMoV15 stainless steel has a solid reputation
This has been on my to-do list. Good job.
My man, absolutely brilliant work!
That was a great video. You were super enthusiastic, and did a great job with the video and the explanations/voiceover.
I’ve seen a couple of your video’s already. The printed knife sharpener made me subscribe (and I don’t even have a printer).
TBH I prefer sharpening my knifes without aiding tools. In the years I learned how to hold the knife and the sharpening tool (witch can be a stone, or steel one) for own preferences of cutting.
But the reason of printing something different from cubes and test models is worthy of recognition.
While I have never used any sort of tool, short of a variety of Arkansas stones, to sharpen a knife the general 3D printing expertise shown in this video is very good. Thanks.
This is brilliant! I'll try it with my straight edge razor, takes forever to sharpen with a stone.
Should definitely work!
Very cool! But I believe that sharpening with whetstones is a wonderful and valuable skill that everyone should take the time to learn.
I love that Ikea knife! I recognized it right away. Been using for over 6 years. Hands down my favorite knife.
Great idea! I love practical printing.
Couple of notes for myself:
1. Holding a knife is a key element here. Shouldn't move, yet should be easy to clamp allowing various blade types.
2. Adding adjustable stoppers, so to use the whole surface of the stone. Otherwise it gets concave soon.
You should be hitting the entire blade with each stroke. When you do this chipping away it will create waves and hard to get equal strokes.
As my boss used to say: "I'm paying for that saw, so I want you to be using every tooth."
This was my only criticism. That and the fact that he should be measuring your angle differential between the blade and the stone. All blades are uniformly flat. Many have tapers which changes the angle of contact in relation to the mounting surface.
Just finished sharpening my knives! this looks much better!
Some time ago I picked up a Lansky sharpening system that's essentially identical to this. I may still print this one. Thank you!
1:11 I'm exactly the same. Man I love your videos.
Nothing to be proud of but, the last time I sharpened a kitchen knife I ended up in the hospital... I still haven't recovered the full sensitivity of the tip of my finger... to be true, it was the second time that finger got butchered: the other time was a long time ago with a wood chisel - it was much worse but I managed without stitches. I guess time do softens you - remember to be safe out there!
I'm curious how it happened? Sounds like a story to learn from.
I’ve had something similar happen while sharpening my knives. Gotta remember to keep your whole hand ABOVE the plain of the blade while working on it. I wasn’t paying attention and ended up filleting off a strip of flesh along the base of my thumb.
I was kind of surprised that there wasn’t a guard which hangs down below the stone’s edge, to protect dangling fingers from overzealous grinding. 🤔
Oh my, this is so awesome, taking 3D printing into the real world. I am a keen cook and devoted 3D printer and creator bringing the tow together is outstanding. The only thing is perhaps better to use stainless steel if possible, more expensive but will pay for itself in the long term.
Awesome. Other sharpeners hold the knife in place with a clamp. Not sure why you chose magnets. You could easily slide the knife under that swiveling backstop and tighten it with a butterfly nut.
Fantastic as always, Stefan!
The 3000 grit and polishing is great for a knife used in a pushing motion like you did, but most organic material cuts way easier with a serrated knife edge like the one left behind after 1000 grit or similiar, drawing the blade over the material.
Indeed. For most normal cooking purposes a knife sharpened on a 800-1200 grit stone is quite sharp enough assuming the sharpening technique was good.
You can have multiple angles on the same blade. Sharpen the blade at 10-15 degrees, then do a few passes at 15-30 degrees with your finest stone. This helps strengthen the edge, while giving relief for stiff vegetables like carrots.
If you sharpened the whole blade at 30 degrees, the cutting edge often can’t make contact, and the knife ends up splitting carrots like a wedge, rather than cutting them.
This design should be for sale on amazon or ebay ...this is great!!
Ich war zwei Clicks entfernt einen zu kaufen aber nach deinem Video… wird‘s gleich gedruckt! Danke! 🤩
Impressive design 😀
Thanks for sharing 👍😀
Such a great video and design!!!! Keep em coming!
Shared online!
Love it! Looks better than my commercial fixture.
Now make it CNC, add coolant pump and some kind of overly complicated filtration system :-P
Ahh! This is essentially an "Edge Pro". I made my own clone of this sharpener about 10 years ago just using some basic stuff from the hardware store and it will make a knife sharper than you can imagine. Shaving hair off your arm is amateur hour for how sharp they can get. Using my emerson folding knife, i can hold up a sheet of 24lb bond paper, let it go and cut it end to end with one swipe. its amazing.
Love the design!. Try redesigning the stopper into some sort of clamp. that way the blade wont slide around that easily. :)
Brilliant. I'd print one if I didn't already own an excellent commercial sharpening jig.
Amazing! I've always wanted to make something like this
Awesome work man keep up the good work lover videos you got my subscription
Man, that's cool. I'll remix it and add some electronics so it'll be fully automatic :)
Thanks for the share!
I have the original (as far as I know) knife sharpener that all these style sharpeners are copied from, and it is awesome. Edge Pro Apex, made locally to me in Hood River, Oregon.
The critical part with these style sharpeners is your stones have to be flat. If they aren't flat, you won't get a good edge. Use a piece of glass and silicon carbide sand to flatten them.
Actually the Ruxin Pro presented as "not the best choice" is quite a good tool. Adding some wood stand to it makes it even better.
As for the 3D printed sharpener i think magnets are sort of Ok but in time they will start taking all the metal in. Also the knife is not 100% stable what may affect sharpening process. But all together it looks quite decent.
I honestly was thinking about doing this but I already have a good version of this. I was thinking of printing a "wicked edge" style sharpener so you can sharpen both sides at once.
I would add a modification to the angle guide to have magnet insert with the base plate with a magnet insert as well so that the angle adjuster is not moving and will stay on while you adjust the angle of sharpening hands free from holding the angle block.
This truly lives up the name of the channel :D
Not a comment of this video, but a request for a video on another topic...
I like your thorough and logical approach to testing things so perhaps you could explore how to get the best supported horizontal surface? Supports seem to break away from complex shapes and leave a reasonable finish but a horizontal plane away from the built platform always seems to end up a mess when I try to print it. The support doesn't break away, or if it does it leaves a terrible stringy finish that's pretty horrible. Could you show us what can be done about it and explore the reasons as to why this is so difficult to get right? Maybe the only solution is to use dissolvable supports?
Sehr geiles Teil!!!
Bin gerade fertig geworden und habe gleich beim ersten Mal ein richtig scharfes Messer hinbekommen!😊
Really like the new Logo. And awesome segway into your sponsor xD
Damn, i was at IKEA today and bought some Weißbier glasses, but missed the knife...
I will definitely give it a try, after i finished moving to bulgaria, building a house, getting the garden started, and finding some time to unpack the 3d printers... not too soon :-/
Thanks for sharing :-)
Holy Shit, actually smth useful. No way I'm gonna print that, the time can be better used for benchies!
b4Bu hahaha ikr, I’m always like “hmm, well maybe I should print another Benchy just to make sure everything is in order...”
Nice, however 3 issues, you should have used stronger magners (thicker) and bigger so they hold down the blade well, and add a clamp over the top of the knife, I know it has to be slim so as not to interfere with the stone, but from the video it looks necessary when your knife keeps moving and you're holding it by hand half the time. When placing the angle calibration, it skids on a rounded part of the tool, causing the set angle to be different from intended, make a stopper/inset for the calibration angle tools so they don't ride up on the inner curve of the tool.
Looks nice, but seeing the knife wigling back and forth I will probably modify the holes for some stronger magnets
intro is better than past!! so cool!!
Great job with it
Great video!
I have those same IKEA knives, they are just the best!
Some strip from old magnetic bed works great for holding the knife. Of course with some modification to the provided files ;)
Love the Benchy fleet.
I might take this and add an adjustable handle grip to either side so that the knife can't move while the mechanism is locked in place - if you don't mind, of course!
Of course! Make sure to share it for everyone else on Thingiverse as a Remix.
Ahahahahahah! That start was amazing!
nice print idea!
One more usefull video, thanks !
Good job!
best sound sfx in a youtube video....ever!
Oooh I've wanted a sharpening setup like this but ready built ones are far outside my budget. This might get it done.
Great segue into skillshare ad :)
the guide tube will work better if square and not round, allowing the stone to pivot only side to side.Quite a challenge to design the encapsulated bearing.Maybe likely only possible with a 3D printer.It kind of reminds me of an old video I saw where someone made square wheels that actually worked.
Also if you don't have a 3D printer you can buy this for about $50 (including the wet-stones)
I learn how to Sharp knife with dish bottom, cup, Stone, different knife etc.. Now i have to print it :D
I actually bought one of those cheap sharpeners years ago but had to print a new anyway after it broke
Have you ever used a electronic knife sharpener? If yes are they any good?
Do you get these rods online or from a store? And what would you use to cut it short of electrical cutting tools?
Stefan, very nice and very educational video, as usual! There is a problem of sharpening drill bits. Why do not you design similar tool for sharpening drill bits?
I gave you a thumbs up just for the opening squish alone. 👍✌🥃
CNC Kitchen. It all makes sense now!
Great design! And awesome new logo! What 3d printer did you use for this?
This was printed on a Sidewinder X1 (aff): geni.us/szVz
You should put a slot in the base to hold the angle block, so you don’t need to fiddle with it while you set the height of the stone. Then you can just lay the stone on the block and tighten the set screw. 🤓👍
I want to build one!
You should attach the different stones on four or three sides of the block instead of changing them all the time.
Because I love your vids I'm going to sign up for skill share under your link.. I need to learn some electrical engineering for building my own ebike controller, custom I have a brilliant idea and want to do it all myself, all the way to mass production.
Dang, that's really cool
@CNC Kitchen how about adding support for a chisel and a plane, that would be awesome
Ich find's cool, dass es auch Mal einen deutsch "großen" 3d-druck TH-camr gibt...
Danke! Jedoch gibts ja auch noch Tom Sanladerer.
On the first tomato maybe a little sliding of the knife would give a different result ?
May have to print this and try it with mower blades. Any way to fit a bastard file where the wet stone would be?
This is awesome. Can I buy this from you?
