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.
Too true! If you don't know where you're going, how can you get there?
You can watch any part of any video in any order you want.
Pretty easy to skip to the end to see what's being made. I can't imagine having the tools to build something from scratch but not the ability to skip through a video
You nailed it. Thanks.
Very true imou671, I could see by the thumbnail
what the idea is, most of use can build anything
without need for instruction if just shown
the concept, this video delivers.
You're a true master of elegant minimalistic engineering! This is simply brilliant yet so stunningly beautiful!
Engineering that's not that is just bad engineering.
You make the best shop-built machinery I've ever seen!
I've seen many sharpening jigs on TH-cam. This is the best... Simple and versatile.
I would enjoy watching you make a drill bit sharpening jig. Take care
I watched 5 seconds, then had to immediately hit pause so I could press the LIKE button & comment how GENIUS this is !!! Thank YOU
I was exactly the same. Credit were credits due. Clever idea
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 can’t believe I watched a man sharpen two chisels at once. That was insane
hahhah true
Actually it's a woman sharpening two chisels at once.
@@philipely4802 delicate hand for sure, but he’s a man if you’ve seen some of his other videos you can more clearly see his body and face if I hadn’t seen his other builds I would have thought the same his panel saw build is the most useful one I’ve seen
@@blacksaber89 Well, his impeccably elegant, unscarred hands are certainly a testimony to the superbly calm, careful skill he shows in his work. I should imagine it's a joy to watch, even for people not into woodwork!
With those narrow width chisels you do need two or a sacrificial piece of something to keep it true 90°. Both the same size, hardness and wear would be best. In a perfect world... I like what they do here!
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
i just made a sharpening jig myself. i wish i saw this video first. this is very clever 👍
Muito criativo e prático, mas acredito que a lâmina vai passar a cortar com uma certa curvatura... se isso não for problema, perfeito. Parabéns!
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. :)
Don't you think it rounds the edges?
@@henaken08 That depends on the loop mount and how well the user is able to move and pressurise the blade evenly. But it shouldn't round the edges if everything is fine.
Thank you! It works exactly like you showed. Now now my wood chisels have a true sharp cutting Edge.
for shear brilliance and simplicity...you got a sub! thanks for this.
I just gotta figure out a clamp for large kitchen knives!
Let me know if you do!
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.)
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
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.
Might be an idea, if you go with a curved edge issue, to increase the radius to as long as you could engineer in the space you had available.
Take a closer look at the structure.
Theoretically, the blade does not round.
@@jisakukobo Exactly. Imagine it doing a full circle on a disc shaped stone
In spanish : maestro del afilado! Saludos de villa Luzuriaga,Buenos Aires, Argentina.
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.
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 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
I copy this jig of yours and works very well. Thank you 🙏🙏🙏
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,
Love that, I can apply it to sharpen my chipper mulcher blades witch I'm seeing many people distroying.
Thanks for the teaching Sir
I just seen this jig and I wanna say thanks please bring out more videos like this
You are incredible and an inspiration to the rest of us. God Bless You Master !
Ты сразил простотой и качеством! Люкс.
Всё гениальное - просто!!! Вы, большой мастер!!!
For whatever reason my chissel is round now..dont know what I did wrong? Looked so easy
I LOVE IT!!! I appreciate a clip where you can see what can an abject do and then how to built it! Congrats!
Здесь что-то не так. Заточка будет радикальной, а не прямой. Нож будет срезать не плоскость, а радиус.
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!
角だけ当たる時間が生まれるから丸研ぎになるね。
Brilliant in execution and simplicity.You are a master at your craft.Building myself one today.
Won't This method put an arc on the cutting surface ??
Превосходно, чудесно, прекрасно! 👍👍👍 Кольцо я бы на эпоксидный клей посадил
🇮🇩🇮🇩👍☕☕
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
Thank you for clearing that. As a hobbyist occacional woodworker it was great to see an uncomplicated setup for sharpening blades precisely at minimal cost.
It's one of the simplest and best ideas I've ever have seen. I will make one my own this upcoming days.
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.
Thanks for explaining this
I don’t understand this explanation. As you can see on the video, the reflections on the bade are definitely rounded. It’s quite clear on the plane blade and even more obvious on the chisels. If the reflection is rounded, how the edge isn’t?
@@Maxime-ho9iv just think about the windshield wipers! They put a rounded mark on the windshield, yet they stay flat on the windshield, is the same principle.
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.
I was thinking that myself, or marked in 5mm increments.
Although if it were marked at say 30 degrees. It may or may not be a 30 degree angle depending on where the cutting edge is clamped in direct relation to the “length” of the arm to which the tool is clamped to it, and it hooked on the anchor point. If total length is longer or shorter then those numbers would be nothing more than reference marks.....
Very nice. Just 2 nuts on threaded rod would be more simple, but that looks better 👍
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
OMG! I have to make myself one of these!! I hate resharpening and so consequently many of my chisels are woefully dull (sometimes I just buy a new one, like the old joke "well, the car's ashtray is full, time to buy a new car!")...
ノミとか小刀ならこの砥ぎでもいいのかもしれませんが、カンナ刃だけはこの治具で研いでも横砥ぎになるので木材（特に杉）が仕上がりません。
カンナを横砥ぎに研いだらなぜ木材が仕上がらないのか、はマイクロスコープで刃先を観察すると分かります。
This man is a robot .... his work is so perfect and his shop is so clean! He has to be a robot!
Universal, simple, and yet precise. Excellent!
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.
Credit for simple design.
Acceptable for short blades such as narrow chisels.
Not acceptable for long blade as planer or knife, the sharpening diection always should be the same as cutting direction. This creates mucro serrations in the blade itself not seen by naked eyes which helps in the cutting process and lengthen the blade usable life between sharpenings. You should always utilize the whole surface area each stroke to keep them flat.
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😴
Да ЭТО не держава уже давно... обычная ЗОНА с паханом!!!
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.
It is wonderful that there are degrees of freedom without changing the angle.
Молодець.
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.
very very very excellent i like it
興味深く拝見しました。面白いですね。作るのも凄くむつかしくは無さそうだし、角度調整は完璧みたいで、私のような日曜大工レベルには十分です。ただ、片べりは起こりそうですね。
I would’ve thought you would get a rounded edge.
Thanks a lot sir for sharing such nice cool and usefull and simple tool thanks once again sir
I loved its simplicity and easy to do
Since I don't have any creativity, so I made exactly like yours:) but I think the lever should be change into metal or smh (if you don't understand what lever that I mean, there is short clip where I show it). Because it will be broken by the time and the angel will not precision anymore. But,. hands down to your idea, this jig is really easy and simple to use. Really amazing!!
*sorry with my grammar
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.

Nice work. Thank you for sharing.
Thank you for sharing your Samurai skills .
Sugoi! Tensai! Please show this sharpening fixed-blade knives.
Thanks for share yours skills!!!
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！
Angeber gleich mit zwei Stück 😆.
Ich mach das immer mit der Hand. Auch beim Messer kam ich mit so einem Gerät nicht auf das Ergebnis wie mit der Hand. Aber bei diesen Werkzeugen probier ich es nochmal. Danke für das Video 👍🏼
確かに発想は凄いですが
本来の研ぐ方向とは違いますね
I like this very much! Thank you.
My first thought was that you are quickly going to wear a path into your stones - then I gave myself a slap on the back of my head as it's very easy to just move your stone very slightly as you go so a different part is used each time. Nice video and inspirational as usual 👍
@CAD Thinking so you're saying that the entire cutting edge would be rounded?
@CAD Thinking No, the corners rounding is done by applying more pressure on each corner in turn for a couple of passes, this does not limit the ability to do that at all
good idea but if you see the blade how it sharpened it ...the blade has a circular pattern and in some of your blades it looks like some edge parts did not sharpen as well so over a few times it will mess up the blade and will need to sharpen it it fully flat again because you are rounding the turn to sharpen it instead of back and forth straight sharpening....so i think its a good idea that can be modified.
Just really brilliant! I am going to bookmark this for later viewing & send it to all of my knife sharpening buddies! Thanks........... 👍👍😉😉👏👏👍👍
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。
this is such an amazing idea. So simple idea but yet so amazing. well thought.
Very close to the one I came up with a few years back, yours is much more refined though. Worked fucking great, but I get tired of keeping up with one more gadget and finally learned how to freehand. So much better.
Saw something like this in a video of Japanese sharpeners at a traditional woodworking event. The upright piece and arm were made of bamboo and the blade was held in against a movable stop on the arm piece by the sharpener's hand.
Would love to see a picture of that
At 4:04 one can clearly see that the cutting edge bevel is skew and that's with the clamp holding down a shaft that has flat edges. Imagine how much worse it would be if a round shaft was clamped to the jig.
長手方向をこれだけ長く取れているとかなり細かい角度設定ができる。素晴らしい発想ですね。1つのジグでいろいろな刃物が研げるのは他にはなかなか見られません。鉋屑を薄く削ろうとしている会(実名を避ける♪)に憧れて、最短で10ミクロンアンダーを出すために私もジグを選択しました。毎日4時間、5ヶ月間で目標達することができましたが、やっと昔の大工さんの見習いになれたような気がします。このジグによる研ぎで十分杉のシラタにツヤを出すことができると思います。デジタルアングルスケールは思いつかなかったなぁ♪持ってるのに… (笑) 替え刃のほうがいいなんて言う大工さんもおられますが、一長一短。私はその一短の中にある創意工夫に心惹かれます。ありがとうございました。
I have tried everything out there and this is simply brilliant! This works better than anything I've seen. Will be building one this morning.
逆に刃を完全に固定して砥石のほうを動かしてみるのはどうなんだろう
very nice, precise production
Excelente, felicidades por su entusiasmo, experiencia, conocimientos y tiempo. Enhorabuena.
I didn't know you could sharpen a blade with lateral motions. I thought you could only sharpen going back-and-forth. Goes to show you just how much I know about sharpening (anything, let alone hand tools). 😬😂🤭
I like this sharpening jig, over others I've seen up to this point. Great idea ...
if you want to be really precise, just keep in mind that the angle changes as you take off material, so you should start with an angle that keeps the edge just slightly off the stone. As you sharpen and remove material, the edge will slowly get closer to the stone and reach the angle you actually want.
4:04 pause
4:05 pause
just what I thought it will create a slanted bevel, if its big knife it will create rounded bevel
NO sure if It was the light angle , but those two chisels did look even. but beside that thanks for sharing..
Is that a throwing knife @ 4:16? Don't be fooled folks, this guy is actually a samurai.
Nice idea, thanks for posting. If you can make it sharpen lathe chisels, in particular, gouges, then it would be truly "universal".
本当にすばらしい 研ぎ治具ですね！
見ていただけるとモチベーションも上がります！
是非参考にしてください！
Truly unique!👍
knife sharpening tools👍
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.
Your work is like thetapy to me. Such great idea's.
Thank you.
The best sharpening jig is a fixed slope. I suggest 25 degrees. No measuring protrusion. No need for secondary bevels. Totally repeatable.
Excellent idea
You can mount disc sander from bottom, you'll save a lot of time sharpening. Great work, as usual :-)
It's not as accurate as doing it by hand.
Mariusz Rutkowski I don't understand what you mean?
@@lambornpeter3922 I guess Mariusz meant the disc sander instead of the whetstone. But i agree with BIg D, it's too fast for such precise tools :)
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？
砥石の番手を変えるたびに角度調整をしないといけない(砥石の高さが違うので)
砥石全面を均一に使用する事が出来ない(ストロークが円なので勿体ない)
早く研ぐ事が出来ない(ずっと同じ方向に傷をつけるので)
研ぎは感覚なので頼ってしまうと砥ぎのスキルが徐々に低下
個人的には道具や治具も技術の内だと思うのでいいと思う。しかし砥ぎの技術すら治具に頼ってしまう位なら替え刃式鉋や鑿でいいような気がするw
刃の動きが支店を中心に円周上を動くという事は外周と内周で移動距離に差があり研磨量に差が生じ刃の角度が変化しそうですね（外周と内周の差×研ぎ回数倍）
Excellent video Sir. Extremely well thought out work.
I have two questions please:
1) The tool must be fixed square to the guide. This is not shown.
2) By using the same part of the water stone, a groove will be created, thus deforming the stone. It must therefore be redressed constantly. This is not shown.
I believe you are from Japan. There are some excellent products not found elsewhere. I'm thinking namely of the lacquer finish you brushed on your board. Also the beautiful brushes. You come from an ancient and very rich culture- this is a gift in itself. My respects.

Ножи рубанка не принимают ли элептическую кромку, сказывается ли это на качестве строгания??
Нет, если камень ровный. Есть специальные камни, которые выравнивают поверхность точильного камня.
конечно принимают! для заточки круговые движения не годятся
@@AndewKu попробуйте лезвие выставить на 30 градусов и покрутить вокруг такой оси (шпильки). Например на столе (в плане ровности поверхности). В каждой точке вращения площадь соприкосновения лезвия с поверхностью стола будет одинаковой.
Поэтому никакого закругления кромки при заточке как на видео не будет.
@@AndewKu Значит если инструмент вращается по кругу то он становится эллипсом . а если вместо инструмента вращается брусок по кругу то инструмент не становится эллипсом . Интересное открытие ! Плоскость соприкосновения инструмента с абразивом ведь не меняется !!!
@@vitaliyblues6619 существует технология заточки сталей, и всё- равно есть неравномерность в плотности точила, резец может иметь зональную закалку, короче это просто не оч правильно, так- поправить слегка можно лезвие.
Genial y muy bueno todos los trabajos. Gracias y saludos desde Canarias Gracias
