I developed and built this on the fly and it in the exact same method as the knife sharpener in my last video, other than it does chisels and airplane irons.
The trickiest part to make in the stepped holder and I show how to cut that safely on the table saw from a larger piece of wood.
The one error I made was not being accurate enough while drilling the holes for the clamping bolts. The shafts of those bolts require to act as guide bars for the moving holder and if there's any slop it will not hold the chisel correctly. Thankfully there was a quick and easy fix for it: drilling the slot in the base and driving a screw to keep the holder down tight to the base. The screw is left just loose sufficient to enable the holder to move easily.
The diamond plate is a credit card size with 2 grits, 300 and 600.
I'll be launch the stl apply for a 3D printed version of this jig (and the depth gauge I utilized) on Patreon soon:

3d printer push stick looking sharp!
I swear, you are some kind of wizard. Ha. As always a great video with the best content.
think I will give this a shot,. I have never been able to get a good edge on a chisel.
If you have a drill press Stumpy Nubs has a cool setup too that’s worth looking at.
That’s a nifty tool, John
I’ve always struggled with sharpening tools and knives correctly. Didn’t matter what I used it ended with mixed results. I think this might be a good way for me to try to get better results.
Thanks for sharing.
This is thinking outside the box. I love to see it. Though I don’t plan on building this exact jig, it does inspire and is a spring board for my own ideas.
We have been with you for more than a few years. You always have something new to share. Thank you for bringing us along one more time. 😊
Very clever. I think I’ll build it with a base that can clamp into my vise so I don’t have to try to hold it in place. Thanks for posting another one of your clever ideas.
Fantastic idea. It takes all the guess work out of the sharpening steps thanks
John, you’ve regenerated your channel since you introduced the 3 d printing. Like a schoolboy on the first day of school. Congrats and keep the ideas flowing!!!!
John, as always your meticulous nature is so amazing!
John, you never cease to amaze me with your skill set. 😊
“This is sharp enough”! I really like the sound of that. 😀
Very ingenious yet simple enough that even a CAVEMAN can use it to get great results.
Some clever engineering going on here! I also like the, sharp enough mentality. Cool vid, thanks!
Honestly, this feels like the best sharpening jig I’ve seen, and I’ve been looking for a while now. I might have to make this one myself! Thanks, John
My sharpening skills are embarrassing, so are my dull chisels. I haven’t tried to master a hand plane, because those are also hopelessly dull. But you may have just solved my problem. Your jig is going on my to-do list! Thanks for the content, brother!
I made something similar a few years ago… never thought about the steps, that’s a really good idea.
I think Sir John just set the new standard for chisel & iron sharpening
