Get the 3D files for this sharpener (and other projects) on my Patreon: www.patreon.com/user?u=865843&ty=h Who doesn't need sharp knives? This sharpener is easy to use, but insanely accurate and produces an edge that's surgically sharp. And you can do it the easy way by 3D printing it, or the hard way from wood. I used beautiful solid hardwood for mine, but any scrap wood will work. Stay tuned for an accessory that turns this knife sharpener into a precision chisel sharpener! Details on that will be on my Patreon soon. The printer I used for this project was the Bambu Lab P1P and the filament was basic PLA.
Thanks Brendan. Making the wooden one wasn't bad because I already had all the details worked out for the 3D printed one. But the 3D printed one took nearly a full week to design, so definitely a lot of time in this one :)
I added a 3D printer to my arsenal a couple years ago to build my PrintNC, and it was my hope that I would still gain utility from it after that build. And I did, that utility primarily being in quickly designing and printing jigs and other small tools for the shop. So it's been a real thrill seeing what John Heisz does with one!
Very well done. The one I made a while ago clamps the knives between a wood square block and a large washer. Have to admit it sometimes doesn't hold a large knife in place during sharpening ( and more difficult to change sides) , this clamping system would solve that. The only thing mine has over yours is that some things are glued with ’’ construction adhesive ’’🤣 . Good video John 👍
Very cool, John! I've had a 3d printer for a long time and just started printing with ABS a couple weeks ago (had to buy an enclosure). Your videos are quite inspiring!
It's interesting to see the differences in design for manufacturability when moving a design from (presumably) injection molded to wood and 3d printing.
Great builds… as always. I’d love to see a post on how 3D printing has impacted you as a maker, and when you think about printing vs building with wood.
Really nice work! I sharpen a bit with Tormek and Tsprof, and I would suggest thart You make another identical "sharpening stone" with e.g. a 1000 grit sandpaper on one side and "the green stuff" on the other to get the same angle when You are polishing. You have of course to compensate for the sand paper thickness and an additional tiny tiny bit to get a slightly steeper angle for the compound side...
Thanks for this, John. I'm bouncing back and forth on a sharpener. One like your wood one, but with some more metal parts like the jaws and round rod. These are pretty nice, quiet to use in the kitchen and easy to put away. And WAY less $$$$ than those Russian ones!!!! I was thinking 1" x 8" blocks for the sandpaper, but your short and wide ones seem to work good too. Or, build a little tilt angle table for my variable speed 3x21 belt sander, and use that. Faster and can do bigger and heavy blades, but would need to use it in the garage (not a big deal as it's attached to the house and just down the stairs). But it's a question of fine grit availability in that belt size.
Since I don’t have a 3D printer, will you be offering a plan to make the wood one? As a patron, could I somehow print templates from the 3D printer files? Thanks for your ingenious ideas, this one is really over the top!
Is there no flex in the plastic in that long rod that the diamond plate is attached to? It looks like it is so thin that it should bend a little, causing the angle of the plate to the knife edge to change. Really neat build. Sharpening knives is always a nightmare.
Im guessing he used Pla plastic for this print, which is actually very rigid and more likely to break than bend. If there is any flex then it's probably insignificant. Other plastics might have more flex.
The weight of the diamond plate is being supported by your hand when you hold the handle. The rod supports no weight (or very little), it's just there as a guide to help maintain the angle. If you're planning to make this and still concerned you can simply replace the plastic with a metal tube.
Seems like you have gotten into the 3d printing but never really got into using your CNC router, what made you like the 3d printing but not really like the CNC router as much?
Those sharpening angles look quite steep. What's the range on a narrow blade like the smaller ones shown here? Nice video on the process, though a lot of sped up footage, which is pretty unpleasant to watch.
Nice build, but man, all I can think is how long until you stab yourself with it. Maybe not stab, because I am not afraid of pointy end, but that you will leave hand exposed under the stone and you will go too far and hit the blade. Maybe add end stop, so you can't go too far?
I doubt is razor-sharp. You can see some resistance on the paper as you cut it. Also, I assume holding the horizontal to the grid is not the best method.
At the 13-minute mark the actual sharpening machine is finally demonstrated. This is very frustrating because you go through making this whole device but we have no idea what all these parts are really supposed to be doing so it's just confusing and baffling. In the beginning you show a bunch of previous designs, and then at the one minute mark you give only a verbal description of what the new one is supposed to do. A lot of RUclipsrs do this kind of thing, but that doesn't make it any less annoying. All the construction you're doing makes no sense when you don't know what the parts are supposed to be doing. So what a viewer really needs to do is skip to the end product I guess and then go watch the beginning of the video again. It would be a lot simpler and clearer if you just showed us what you're making and just how it works before you make it.

This was great because of the side-by-side build comparisons. There was a lot of time invested in this, thank you John.
Best Wishes, B.

Genius as always
Nice! Will be making one of these this week!
These are really neat. I think I like the wooden version just on looks. 😊
True mastery. Very cool that you made it out of both materials.
Cool stuff! I still do it "by hand" and my results are inconsistent, to say the least. I should try this type of sharpenner.
Maybe 3D print some push blocks for the table saw?
Really love that you made it out of wood as well, it's so cool to see both side by side
Very well done. The one I made a while ago clamps the knives between a wood square block and a large washer. Have to admit it sometimes doesn't hold a large knife in place during sharpening ( and more difficult to change sides) , this clamping system would solve that.

PLA is the new PL Premium :)
Well this is timely! Thanks John!
It is amazing how your mind works!!! Thanks for sharing!!!
I think some rubber grips on the bottom of the base would be a nice addition
Brilliant as usual! I can’t wait for your videos.
Really like the wood version. 👍
Very cool, John! I've had a 3d printer for a long time and just started printing with ABS a couple weeks ago (had to buy an enclosure).
Your videos are quite inspiring!
Very inspiring Sir, as always
Amazing , very inspiring , thank you for your work !
Well done John! Sent this video to one of my friends who is a knife collector and likes them sharp! 👍👍🔪🔪
Interesting to pull a wedge horizontal to clamp vertical beyond a pivot 👍
THANKS FOR THE VIDEO, KEEP UP THE GREAT WORK.

John, you're having just too much fun with your printer. Go guy! Thanks.
Great video. Very sharp!
This video must have had SO many hours invested in it! Both great solutions, great sharpeners and top notch video 👍
Very helpful, thanks....😊😊
Really nice work!

Really good stuff John. Great video thumbs up.
Pretty darn neat.
Fantastic build, John! Really well done!!! 😃
Stay safe there with your family! 🖖😊
CNC Kitchen made one very similar. I think the files are on Printables
You can also source "rubber" from resistance bands, commonly called "Theraband" strips. That's what I use. :)
If you wouldn't mind saying, what glue did you find worked best for Theraband to wood? Thanks very much.
If you're going to use that much Super Glue, Accelerator is very most definitely your friend. Huge time saver.
Cool 😎
Did you notice any additional flex in the printed version?
Fun!

Looked at your plans for sale and couldn’t find the wood version of this sharpener.
this looks like a much better version of my lansky sharpener
Both look great. I like the look of the wood one best. You say the 3D version is faster. But how much time did you take designing the files?

Could you make one to sharpen planer blades
I really enjoy your 3d print videos! 🤓
Thanks Pat :)
Seems like you have gotten into the 3d printing but never really got into using your CNC router, what made you like the 3d printing but not really like the CNC router as much?
nice
Where did you get the diamond plate? Can you give us a link please?
Doesn't quiteseem like it's possible to get an acute edge around 15 degrees on it. Looks more like a 30 degree angle which won't be near sharp enough?
Hi John how about something easy to sharping chisels, I have more trouble sharping my chisels I can never get my chisels to say sharp, thanks John
Coming Soon :)
do you think a 3d printed router plane would be strong enough to remove material
The beauty of the wood vs easy of fabrication (once You habe the design) of the 3d printong...
Hey John, I’ve been missing the speaker/audio content on your other channel… anything in the works?
I appreciate the straightforward title and thumbnail. I try to vote with my upvotes/comments to discourage click bait titles on RUclips.
Oh, here you are😂
Those sharpening angles look quite steep. What's the range on a narrow blade like the smaller ones shown here?
Nice video on the process, though a lot of sped up footage, which is pretty unpleasant to watch.
You should be cutting tomatoes instead of paper!
Nice build, but man, all I can think is how long until you stab yourself with it. Maybe not stab, because I am not afraid of pointy end, but that you will leave hand exposed under the stone and you will go too far and hit the blade. Maybe add end stop, so you can't go too far?
But no special adhesive 😢
I doubt is razor-sharp. You can see some resistance on the paper as you cut it. Also, I assume holding the horizontal to the grid is not the best method.
Ach, wie gut dass niemand weiß, dass ich John Heisz.
It’s hard to go back to metal knives once you use ceramic. They keep the edge and don’t react with organics.
I wonder how @OUTDOORS55 would react to this video 🙃
Was thinking the same 😆

As much as I love woodworking, and so enjoy your videos; I have to say that your inventive talent is being wasted here.
just a copy of many other commercial products out there nothing novel here.
You had the CAD model, you could have printed templates, but you hand drew the layout. Just sayin'
The wooden version is the bomb, and everyone knows it. Hopefully soon you will become bored with the machine.
