Universal sharpening jig 

Appreciate you showing us how its used before you build it. Often people do the opposite and the audience has no idea what is being built nor the particular purpose.

I made a copy of this sharpening jig. What a brilliant, effective solution! Thank you for sharing it with us. I did rework it a little to include an adjustable length arm to better accommodate different length tools I sharpen and different thickness stones/plates.

Simplicity it’s self 👌 a superb jig that all workshops need 👏

I've seen many sharpening jigs on RU-vid. This is the best... Simple and versatile. I would enjoy watching you make a drill bit sharpening jig. Take care

You make the best shop-built machinery I've ever seen!

You're a true master of elegant minimalistic engineering! This is simply brilliant yet so stunningly beautiful!

Thank you! It works exactly like you showed. Now now my wood chisels have a true sharp cutting Edge.

i just made a sharpening jig myself. i wish i saw this video first. this is very clever 👍

for shear brilliance and simplicity...you got a sub! thanks for this. I just gotta figure out a clamp for large kitchen knives!

Great job on the sharping jig Friend! Thank you for sharing the video with us!💖👍👌😎JP

Thank you. I like it. This would allow me to continue to use sandpaper adhered to marble tile. Simple. Unique. May the Creator continue to bless your ingenuity and skill.

Love that, I can apply it to sharpen my chipper mulcher blades witch I'm seeing many people distroying. Thanks for the teaching Sir

Thanks for sharing! It's tool that I'm in need for. 🙂

Thank you for sharing your Samurai skills .

An absolute functional and easy to use mechanism. Would the movement of the arm being centred and fixed create a circular motion in the object to be sharpened? How ever small. Thanks for the video

Universal, simple, and yet precise. Excellent!

wonderful! thank you for taking the time to share this with us. your video is easy to understand and helpful. It looks like you are using powder on glass while sharpening. I have only used waterstones and abrasive sheets on glass. can you describe this a little more? what kind of abrasive powder do you use? thank you for sharing.

Muito criativo e prático, mas acredito que a lâmina vai passar a cortar com uma certa curvatura... se isso não for problema, perfeito. Parabéns!

Just really brilliant! I am going to bookmark this for later viewing & send it to all of my knife sharpening buddies! Thanks........... 👍👍😉😉👏👏👍👍

Super genius!

作品の用途や効果を示してから、製作過程に入るという、あまり見られない見せ方に感心しました。 無言でよくわからないものから作り始めて、最後の段階まで何を作っているか分からないDIY動画は、退屈で途中で見なくなります。この動画は良いですね。

Brilliant in execution and simplicity.You are a master at your craft.Building myself one today.

this is such an amazing idea. So simple idea but yet so amazing. well thought.

You are incredible and an inspiration to the rest of us. God Bless You Master !

such a great job and conception !!! Thanks a lot for sharing

Clever use of odds and ends, Kudos

It's one of the simplest and best ideas I've ever have seen. I will make one my own this upcoming days.

Ottimo lavoro esecuzione esemplare. Fabrizio 🇮🇹 ciao 🖐️

I like his approach on acquiring shop power tools, if I don't have it, I make it out of what I have! This is the exact capability needed if people are going to colonize Mars, it's nice to see it hasn't died out completely in our throwaway society.

砥石ズラしていけば全体使えますね。構想力が毎度毎度すごいですね。いつも創作意欲が掻き立てられます。

I watched 5 seconds, then had to immediately hit pause so I could press the LIKE button & comment how GENIUS this is !!! Thank YOU

This was so satisfying.

Clever, as usual. Thanks

Hi, seems like positioning, angle and clamping of the blade to be sharpened, are very important. You make it look easy. maybe share a little more on that. thanks. love your stuff.

When you were adjusting the sharpener, I kept thinking to myself, how is he going to push the blade on the stone because it's hooked to the rod in the back which is holding the angle. I totally missed the whole idea that you don't have to push the blade back and forth, you can go side to side as well. That was so cool. I'm making one of these today...

I love your home made machines. Sugoi!

wow nice Jig, great work

Nice idea, thanks for posting. If you can make it sharpen lathe chisels, in particular, gouges, then it would be truly "universal".

I was ready to spring for a mfr. jig and it would not of been as multi-purpose as yours. I am anxious to buid your system. Impressive.

This is perfect! I can't sharpen to save my life and this would remove as much of the human element (me) from sharpening as possible! Best jig I've seen so far

Гениально, просто и максимально эстетично. Спасибо за видео!

Excelente, felicidades por su entusiasmo, experiencia, conocimientos y tiempo. Enhorabuena.

Wow,thank you for sharing. I like your idea 🙂

I LOVE IT!!! I appreciate a clip where you can see what can an abject do and then how to built it! Congrats!

Que gran idea y que buen trabajo. Te felicito.

I like this sharpening jig, over others I've seen up to this point. Great idea ...

thanks for a great video and lesson. I must do this.

Amazing, best sharpening idea I have seen

I can’t believe I watched a man sharpen two chisels at once. That was insane

Perfekt! Gratulation, I salute you!

very nice. it's kind of a chimera, a bit like a wicked edge and a bit like Edge Pro. I like it! I'm going to build it. Thanks Mr. Koubou!

Ты сразил простотой и качеством! Люкс.

You have an excellent channel. Could you please tell us what kind of sharpening stones you used & the different grits? They looked like very nice diamond compound stones. Thank-you.

Muy, muy, muy Buen Video. *¡¡¡ BUEN TRABAJO !!!*

Hello great video! I'm looking at getting a Japanese made 18 guage nailer and I'm looking at the Makita af502 and the kanematsu sfn-50. I'm afraid I might not be able to get parts to fix the kanematsu given that the company got eaten by Makita. Do you have some experience with these tools and their parts availability?

Muito interessante. Parabéns.

Me watching this video: Ok, it's a real nice sharpening jig. @5:21 Oh, he 's showing his sawing jig, that he uses to make it. Nice it's hang up to the wall for less chaos in the workshop. Wait, what... ? It's screwed to the wall? It's not only hanging there to be put on the desk? That's awesome! :D :D

I just seen this jig and I wanna say thanks please bring out more videos like this

Absolutely brilliant concept and an elegant execution. Wish I could give this a hundred thumbs up!

Loved it! I was also intrigued with your panel saw. Do you have a built video or plans

Wow that's sharp to cut straight down is a very fine edge. But it's important to remember this craftsman uses high quality tools and equipment so the result you will get will be as good as the tools you have.

Best honing station I have seen yet

great, will make one for my all blades

I copy this jig of yours and works very well. Thank you 🙏🙏🙏

Idea geniale complimenti bel lavoro

Превосходно, чудесно, прекрасно! 👍👍👍 Кольцо я бы на эпоксидный клей посадил

This is genius!

Genial y muy bueno todos los trabajos. Gracias y saludos desde Canarias Gracias

Thanks, this is my request 👍👍👍

Inspiring. Easly improveable.

これは便利！　研ぎが苦手な私にも出来るかも　テクニックを公開していただき大感謝です！

What do you suggest for something similar to sharpen PLANER BLADES that are 10 inches long? I love this video. Absolutely amazing. Your help is wonderful

Es una idea genial amigo gracias por compartirla te saludo desde mexico

Great sharpening system. I would add just one small feature: the arm the tool gets affixed to could have a clear centre line marked along its surfaces to ensure accurate alignment. That's the only thing that could maybe improve this.

Thank you for this. I’m amazed having read most comments at the fundamental lack in mathematical/ geometric knowledge. Several people with cad knowledge have answered correctly FLAT STRAIGHT blades. Now having said that their are discrepancies in the set up and as mentioned the application of correct pressure could be an issue. But great idea worth developing

工具を使う仕事していますが、JSK-koubouさんの工具や作業場が恐ろしく手入れが行き届いていて驚いています。

毎回奇抜で面白い映像！面白くよく見ています。

Just sub'd to the man. Your vids are a nice discovery to a tradesman from Aussie!

Simple and elegant, brilliant!

Good video. Thank you.

you have beautiful stones and beautiful cutting tools, but I believe that using the stone in that way creates micro pits on the stone itself and over time you have to rectify it. one-side-bevel tools, such as chisels, kiridashi and plane blades, but also scandi beveled knives are very easy to sharpen without any support guide precisely because the single bevel gives the right angle automatically. although I find the way of rubbing on the stone anomalous, I find your technique effective. the Bevel Box is very interesting. Greetings from Italy

​It is wonderful that there are degrees of freedom without changing the angle.

You just made my day!

Excellent idea. Thanks to "Silk Hands" Koubou for share. Regards from México.

Fantastic! What kind of sharpening stones are you using?

You can mount disc sander from bottom, you'll save a lot of time sharpening. Great work, as usual :-)

Всё гениальное - просто!!! Вы, большой мастер!!!

I really liked your wall mounted panel saw. Do you have a build video? Do you have plans?

La idea sin duda es brillante, cómoda en su desempeño y con un final espectacular pero no todos tenemos esa variedad de maquinarias para su realización. Solo aquellos que poseen un taller estarán en condiciones para obtener una pieza similar. El resto no podríamos aunque se pusieran muchas ganas. No me vengan a decir que antes se lograban cosas increíbles sin máquinas, hoy eso cambió porque artesanos que trabajen al modo antiguo no hay y el tiempo juega en contra. Mis sinceras felicitaciones por el instrumento, seguramente el más simple y de mejor logro de los que he visto,

Just fascinating ! Thanks a lot !

What is the bracket you used to clamp down the iron? You used the same thing on your adjustable mortising router jig. Somebody in the comments said they were termination loops (from the big box store) but I ordered some and they were way too large. I ended up making my own but I’m still curious what yours are?

Simply brillant. Thanks for sharing it

The grinding surface should be completely planar, since the rotation of the arm is following a cone and everythng attached to it follows the groundplane of the cone. Also aligning the stone tangential and shifting it, is pretty efficient with regard to wear and tear of the stone. Really really nice idea. But sorry, I'm a German, I have some critique too. Or better said improvement suggestions. Your threaded rod and the mounting of the arm create a big play and your planar surface is compromised by that. The threaded rod is moving pretty badly, which you can see at 1:30 . To improve that situation, you could add two more rods in a triangle to guide the arm mount. Or you could add some kind of support beams to your rod. The other issue I see is the mount of the arm. The loop has a play by itself. The arm can move back and forth, which results in a non planar grinding surface. You could either work with a cardan shaft (which is probably more expensive) or you could decrease a bit of the play by adding a wedge into the loop. Please don't get it wrong. I do really like what you do. It's very inspiring. I just want to help a little. :)

Simple, easy, effective. Top.

I’m making me one of these. Great idea. I especially like the simplicity of the angle gauge to determine correct angles for the various tools.

これは良いですね。素人でもできそうです。

Pretty amazing work, dude! 😃 Really fantastic jig! Stay safe there with your family! 🖖😊

Nice work. Thank you for sharing.

Excelente , gracias por compartir tu conocimiento y trabajo👏👏👏👏👍
