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.

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

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.

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

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.

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

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

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。

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。

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

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!

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

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.

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

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

Whilst I think this will slightly round out the left and right edges, I'm not sure it would be enough to make a functional difference. I think we should remember that there are many small preferences amongst people for how blades are prepared, micro-bevels, slightly different angles, flat vs. dished backs etc. Not one way is right or wrong, it depends on the tool, how it is to be used, and most importantly the person using it. And we should remember there is a difference in the tradition of Japanese woodwork vs the western style. I can even see an advantage to blending out the sides slightly in certain circumstances. And in combination with the digital angle gauge this'll be a lot quicker to set and select an angle than measuring the protrusion of the blade in the standard Eclipse-type jog and a heck of a lot cheaper than a Tormek! I'd like to say thankyou for giving me another option to think about at the very least! Always enjoy these videos.

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。

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

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

Thank you for sharing your Samurai skills .

This was so satisfying.

Clever use of odds and ends, Kudos

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.

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 !

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！

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...

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

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

Clever, as usual. Thanks

Надо изменить позиционирование детали. Сейчас у вас задействована малая часть точильного камня. Он будет быстро и неравномерно изнашиваться. Если вы разместите нож рубанка под углом к опоре, а не соосно, то работать будет намного больше камня. (It is necessary to change the positioning of the knife. Now you have a small part of the grindstone involved. It will wear out quickly and unevenly. If you place the planer knife at an angle to the support, rather than coaxially, then a lot more stone will work.)

Ты сразил простотой и качеством! Люкс.

これは良いですね。素人でもできそうです。

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

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.

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

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.

Best honing station I have seen yet

wow nice Jig, great work

In spanish : maestro del afilado! Saludos de villa Luzuriaga,Buenos Aires, Argentina.

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.

Que gran idea y que buen trabajo. Te felicito.

I love your home made machines. Sugoi!

Ottimo lavoro esecuzione esemplare. Fabrizio 🇮🇹 ciao 🖐️

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!

Muito interessante. Parabéns.

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

Всегда смотрю работы jSK koubou от начала до окончания. Вышел всяких похвал! Похоже на работу художника. Ко всему ещё полированные ногти и нет грязных равных перчаток. Эх-ма, за державу обидно😴

Universal, simple, and yet precise. Excellent!

毎回奇抜で面白い映像！面白くよく見ています。

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.

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

great, will make one for my all blades

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?

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

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. :)

Won't This method put an arc on the cutting surface ??

Super genius!

최고입니다. ^^

Amazing, best sharpening idea I have seen

円周で研ぐとか２本同時にとか凄い

Inspiring. Easly improveable.

This is genius!

興味深い発想ですね！

Fantastic! What kind of sharpening stones are you using?

本当にすばらしい 研ぎ治具ですね！

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

This reminds me of the Lansky sharpening system, except they have you move a small stone across the blade. For very specific sized blades, it works great! For everything else, it's frustrating at best and unusable at worst. This looks like a much better system, even if it's quite a bit larger (you could fit the Lansky system in an apron pocket). What you're doing obviously works, but is there a functional difference between sweeping the blade side to side vs moving it forward and backward? I always thought you had to sharpen perpendicular to the cutting edge.

Perfekt! Gratulation, I salute you!

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

This man is a robot .... his work is so perfect and his shop is so clean! He has to be a robot!

You just made my day!

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

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

Idea geniale complimenti bel lavoro

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!

Just fascinating ! Thanks a lot !

It will NOT create a "rounded" frontal cutting edge for the chisel, but a pretty accurate straight lined. Since you pivot the arm around the bolt on the column, the cutting edge itself is always on the same geometrical plane. When you are rocking either the stone or the blade inside the holder (only one at the same time), that could be creating a circle shaped front. But when we consider the length of the arm, the introduced angle is very small compared to the bladefront. I am sorry for the amount of words,but I couldn't explain it in fewer. The jig is a great work and your working place always looks so clean. Great job! Hopefully this will not be lost.

凄い！そんな研ぎ方あるんだ！？ 扇状に研げちゃいそうだけどデメリットは無い感じなんですかね？

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

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.

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

Wow! Awesome! Does sharpening on a radius automatically chamfer the edges? Or would you do it the same as with other honing guides and just put extra pressure on one side then the other? I’m kinda new to wood working with hand tools. 0:21 whoa! That is a thick plane iron! 11:55 not gonna lie… it made my OCD twitch when you screwed that bracket down with the wood scraps still on the board, lol. I was a bit surprised based on how immaculate your shop is. Great video!

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?

発明家すぎる‼️

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.

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

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.

Good video. Thank you.

ランスキーのシャープナーの大型判ですね、いいですね！

Truly unique!👍

Next level stuff.

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

Maravilha...Parabéns... Grato e Abraços...

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

Stanley Tool Co. made and sold a tool specifically for sharpening plane blades as in this principle shown here. The tool is an antique now but still available in places like eBay. I have one and it does a perfect job.

厳密にいえば、弧を描く軌道になるので、常に一定の角度で刃先が砥石にあっているわけではないですけど、両端がちょっと違く角度になっても使用には支障ないんでしょうね。　治具の構造は簡単だけど、本当にきれいにできていてほれぼれしますね！素晴らしいです
