Making the "Impossible Joint" 四方鎌継
Making Shihou Kama Tsugi (four-way goose neck joint). When you first look at it, it can be confusing as this joinery is on all four sides, without a way to be taken apart. But this joinery actually slides diagonally, making this "illusion" possible.
The wood is Walnut and Birch.

after watching this, i was inspired and fixed a broken chair leg with duct tape.
Too complicated! Instead I watched a video of a guy repairing a chair with duct tape --- was it you?
I watched an instructional video on KZhead on fixing a chair with duct tape, then I made an instructional video about fixing a chair with duct tape, and now others can make instructional videos on how to fix a chair with duct tape..
@@irieanimalcare2736 Excellent news! I've got beer and crisps, I'll watch them all while sitting on the ground. I'm hoping to acquire a broken chair at some point in the lockdown.
Lol
Well, doing something is better than doing nothing.
I had accidentally turn on auto captioning before this video. Whenever chiseling would occur, a caption would say “Applause”. Who am I to argue with that.
Underrated comment
It works, 😱😵😵👍
I am in the Nobel Committee, and I think I know who wins this year's Nobel in Literature
👏👏👏👏👏👏👏
Hahaha I am surprised when I saw "Applause " caption.. wtf
My dad is a carpenter and he's always been impressed by Japanese woodworking. I get it now.
This is very interesting to me, not to mention very impressive. No intro, no dialogue, just a mind blowing level of precision and commitment to the craft.
I swear i spent 70% of the video admiring how sharp his chisels are.
Japanese steel is top notch shit
Thank god! I'm not the only one 🙂
Same here
My wife used one of mine as a screwdriver when she could find a flathead
@@apcook34 haha,thats just something to use next time she says she puts up with so much,just be like " says the women who ruins a chisel i have spent and hr sharpening over a screw haha
Making an impossible joint is now legal in 16 states.
It's 4:20 somewhere.
Was already legal for ages where i live 😊
😄😁☘
what
Lol!
Amazing. The use of 'basic' hand tools is stunning - a clear demonstration of craftsmanship. Inspiring !
Not the kind of joint I was expecting, but still a solid 10/10 execution.
Same
This was exactly what I thought it would be. Just like in the thumbnail. "Impossible joint" is a magic trick / an illusion. Drugs are for stupid people, nobody should make videos of them. :)
@@siipi6331 haha drugs bad
@@leviathan3630 Yes, they are. ;)
Same, but I made one out of rizla and burned it anyway😂✊🤪
When I saw impossible joint making, this isn’t exactly what I had in mind
I was expecting other kind of joint
Thats why I clicked lol
That's the bait
Same here mate
free the joint. legalize it!

Happy to hear that! Cheers! 🙌
I cant believe how many fantastic videos are ruined by obnoxious music.
@@silverishme8675 haha yea
Sure, your preference! Cheers
@@silverishme8675 Sure, your preference! Cheers
This video isn't click bait, but the joint itself is.
I too was disappointed that it is not impossible
It's smart and plays on pretty clear assumptions. When I saw the diagonal profile I actually laughed out loud and thought it was brilliant. This is one of those things where if I bought one I would say "I not sure how they did it either but I'm sure it isn't a veneer"
I think so too because it’s an illusion, and a lot of extra work for something that probably isn’t as strong as a simpler joint and weaker than what it appears to be.
@@Anvilcjl well no,because this joint have actualy been used time and time again in Japan
Yall really suprised that the video "making the impossible joint" is not about making an acually impossible joint. Like duh, he cant make something that is impossible to make. The joint is called "impossible to make" coz of how it looks
This is amazing. Elegant and precise. Woodcrsfting in this manner is so rare these days. Thank you💛
Elegant and precise are often used to describe musicians, authors, athletes. I love that it can also be used for this. Artistic design that's functional.
What an incredible joint to make! The super sharp chisels and the accuracy of the cuts with the saws, inspirational!
The noise of the sped-up chiselling is sooo satisfying
Its perry the platapus!
Its like woodpecker.
Watch at 2x speed. It's even better
Trrrrrr trrrrr tar tarrrr
It's like a musical machine gun
I'm honestly impressed by the craftsmanship. I wasn't expecting the hand tools!
I’m not sure this would be really doable with power tools. The wood work is too delicate for that
@@DK-lz7kg I agree. Sometimes, you need the lighter touch of a human handsaw rather than a circular saw. Much more precise, even if it takes more time.
@@DK-lz7kg maybe a CNC machine but idk
His skills are at peak perfection
@@yyhrva5605 Yea I've seen other youtubers do it with a CNC machine, the fact that this guy did it all by hand is amazing
Traditional Japanese woodworking is positively beautiful, as well as ingenious. Those chisels are stupid sharp.
I am thoroughly impressed! It just shows me how much I have left to learn. I love this type of content, as opposed to the videos that show simple hacks, because this type of video shows you that there is still virtue in dedication and doing hard things. Very inspiring.
Well said
I watched the whole video just to find out how it fits
I watched the end of the video just to finds out how it fit sooner
I skipped to the end...
Noob. I skipped to the last minute
I dont even play the video. I just let my wife tell me how it fits after she done watch the video.
Totaalmeente.. increible ingenio
I'm more impressed with how sharp your chisels are. Jesus.
Yeap, especially when chiseling against the grain
I was thinking it's the wood being soft or some shi lol
Same there - jeez, one slip and down a finger or two!
I took a woodworking class and the first two days were spend on how to sharpen cutting tools. This was on timber frame houses. Wish I could remember it now.😄 neat video.
It is necessary.
Japanese woodworking craftsmanship is second to none...💯☝🤫
I am going to a timber school soon. And I have tried to make wood joints before and failed horribly, but I know how much patience and perfection you need for these thing. So great job 👏
His control is amazing. Notice how he takes small cuts as he chisels. Also notice the backside of his chisel is like a mirror.
You noticed two great points! Cheers!
That's really how chisels are meant to be used. Same reason chefs don't bludgeon wildly with a knife. It's a fine skill but an essential part of woodworking otherwise you're not going to be able to make anything presentable.
It is said you can tell a lot about some one based on the condition of their tools. Amazing work and amazing skill.
The fact that he did it all with his hand tools and did not use machines makes it so much better.
Judging from the sound he used a hydraulic hammer. Since this is youtube, where users are slower than elsewhere: I am joking. And if you were just enraged, then this means you, yes.
Tbf that's how all carpenters make joints if they are worth their salt
@@bur2000 ???¿???
@@bur2000 Looked more like a hydraulic arm than a hammer to me. That sawing was of Steve Austin standard. For anyone under 40, not the wrestler.
it's the artistry of the design of the structural integrity that makes it 'better' - NOT the lack of using machines.
Cool stuff. I love the showing of the whole outside before any marking/shaping. It's fun to pause after seeing the 4 faces, and take a moment to figure out the possible inside shapes!
I have no idea how the algorithm put this in my feed, but it was absolutely captivating.
I love how the title doesn't even mention that it's done entirely with hand tools. Masterful work.
@@marxgalacticambition7023 nope, it entirely matters how it was made.
This guy makes it look easy, but that precision with handtools? That's serious dedication to craft and project, with a heap of talent to boot.
If you keep talking like this you'll never achieve anything in your life
@@cube4547 Ahh yes appreciating other peoples hard work means you will never achieve something.
It looks so difficult because of the speed-up. Wood-carving is so slow that as long as you're using the proper techniques and not too much brute force, accuracy isn't a problem. It's mostly about knowledge and keeping your tools in good condition.
I think wording it as hard work, practice and skill would've been better than talent
@@dovydasgrigas441 there's no such thing as talent. If you keep thinking you need some magic, help from god or genetic luck to be relatively successful, skilled or knowledgeable then you'll never be any of those things.
I don't know what's more impressive. The layout of the work or the incredible chisel work . Truly amazing art.

There's a bridge in Cambridge, England, that was built without nails.
Yeah I'm glad I got to witness fine Craftsman but damn
They built entire castles in Japan
And yet at the same time because this one join is this labour intensive, why it is also functionally impossible in today's world
@@greebj you can automate the procedure, though
Amazing Japanese wood craftsmanship!

Bravo. The precision of each cut is mind bending, and not a piece of sand paper in sight! 👏

I love how impossible it looks at first glance, then finding out the solution is very simple - or as simple as it could be if you're a master carpenter!
Absolutely fascinating. World-class pin-point chiseling to create a wonderful joint. Which is not only beautiful but also seems to be strong as well. Lovely stuff keep it up!
It is in fact an illusion, but one of absolute brilliance. This is what woodworking is all about. I couldn't hope to get something like this right if I tried it. Hat's off to you!
I love watching things that make me realize just how much I suck at everything.

Maybe stop watching and learn something instead? Naaaaah, too hard.
@@HandledToaster2 people learn by watching though.......No?
@@chaosismyway690 have you learned woodcrafting from this video?
Man, this kind of chisel work always blows my mind and impresses the hell out of me because I know there's no way I could ever achieve that kind of perfection, shaving off exactly the right amount, getting all the flats just right. If any one of then isn't just right then the piece either won't assemble, or it might have gaps. That level of precision is just exceptional to me.
You could if you have the right chisels and patience
This isn't talent. It's a skill through repeated actions.
@@tmmnago2722 This guy gets it. There is nothing to prevent the average person from achieving this level of craftsmanship, save for years and years of practice.
@@totsuka2213 well I think the dedication that must've gone into achieving this level of skill is very impressive
Dude you absolutely could make this, all it takes is patience
Nothing but a saw, chisel & mallet! No power tools...very intricate!
Finish carpenter here - genius work. Cheers!
That flow of sped-up background noises (church bells, cars, voices et all) is a treat on its own.
As a Danish carpenter and woodworker, I find this very fascinating. I haven’t seen a joint like that before. Beautiful!

No machines, no chemistry magicks, not even sand paper. Only chisels, saw, wooden clamps, some hammering. And godlike dedication.
those chisels were sharpened somehow
@@mro4922 You can hand sharpen to a mirror finish like that... I've done it multiple times over the last 3 days.
@@mro4922 probably on a stone.
That lumber is definitely sandblasted before he buys it tough
And to think ancient chinese slaves had to do thousands of joints like these for buildings
So satisfying watching a master craftsman at work!
If you break this joint down to its basic components it is somewhat simpler to understand. It is basically a double mortise/tenon joint done at a 45 degree angle with the twist of sliding dovetails added to the end of each tenon.
If there's one thing I've learned about "impossible joints," it's that whatever it looks like is a lie.
Its called an optical illusion, magicians use them all the time this was a neat example of one
@@ronaldharris6569 always do amusing that usually the trick of the trick is pushing the boundaries if credulity. The tricked watcher can't even conceive of the work that went into the staging of a seemingly simple trick. A often it's about putting in a lot more effort than people would suppose anyone would invest for the result. Magic I mean, not the woodworking.
Is a very beautiful joints, and that is the meaning with this joint

ただ、ただ、素晴らしい。日本人の誇りが、この動画に存在する。
Always a pleasure watching a sharp chisel at work.
I usually scroll through videos like this to save time, just wanting to get an idea of how the affects are achieved. But the precision and sharpness of the tools were mesmerizing. Had to watch it all the way through. If any of my tools were that sharp, I'd be a danger to myself and anyone within arm's reach. Truely amazing work. Thank you for the video.
Thank you! That's great to hear! 😊
Same here, first I had to guess at how it pops together, then I wondered how he got those tools so sharp where he could push them through hard wood. I ended up watching everything
sharp tools are safer than stump tools😉
@@Hermelin.G1 Exactly... Less force is required to push the tool through the material. Less chance of a slip.
@@jimmurphy6095 absolutely correct!
Something about the sped up sounds of carving and chiseling is a bit mesmerizing
The crazy thing is that you might think the video maker is "tricking" you until the ending, but actually, the "trick" is right there in the description. It''s just that the video is so mesmerising that, well, who's gonna *read* before hand? Congratulations for the great work!

The chiseling is pure ASMR

Am i the only one who thinks that this is really satisfying? Both the sound and seeing him slowly chisel away at the wood
"slowly"... I wish I could chisel away hardwood at this speed with this precision. (Yes, I'm aware the footage is sped up)
I would make an unfixable mistake so quickly. There isn't a single step to this process that I could not mangle beyond recognition. THOSE are some tight seams, bravo!
