To see how swords were traditionally made back than and how they still use the same methods today is awe inspiring. Hope this method never dies, because when it does you'll never see a sword quite like it, ever.
I like watching people work who know exactly what they are doing, why they are doing it that way and knowing that they are doing it well. Watching master craftsmen and artisans at work is something I really enjoy.
This is exactly how they would've done it for 1,000 years. Exact same tools and techniques. It's the most authentic and traditional forging process I've seen on UA-cam so far. Incredible

Did they light that tinder paper by heating up that rod through hammering it? That’s a lot of effort and dedication even before the actual forging even begins.
Iron sand in Japan is titano-magnetite iron sand contained in granite weathered by magma, and is called Masasatetsu. Iron sand weathered from basalt is called Akomesatetsu and contains titanium. This iron sand has low phosphorus and sulfur content and contains vanadium. Phosphorus and sulfur are impurities that make steel brittle.Vanadium strengthens steel. Iron ore and coal are high in phosphorus and sulfur and do not contain vanadium. In ancient Japan, slag was called noro, and the process of removing slag was called noro dashi or noro shibori. In tatara ironmaking, the iron sand is semi-molten by keeping the furnace at 1300℃, but only phosphorus, sulfur and impurities and slag are melted and discharged. So impurities and slag are removed from the material tamahagane of katana. It is produced using the same tamahagane material as katana, a high-end kitchen knife made in Japan. The low-temperature reduction method makes the grains of the steel smaller, so the steel has excellent toughness. Vanadium makes the steel malleable and easy to roll, making it easy to fold. By folding, the vanadium is finely dispersed and combined with carbon to form a fine metal structure, so the katana has excellent hardness, abrasion resistance, corrosion resistance, and toughness, and becomes beautiful when sharpened. Hitting the steel with a hammer removes the carbon with a spark, so the carbon content drops to 0.7%, which is suitable for katana. The approximate amount of carbon can be determined by the shape of the spark. By folding, the steel of katana is in a state where austenite and martensite, which have different hardnesses, are dispersed. When a katana is sharpened with a Japanese sharpening stone, the austenite is removed and martensite remains, so the blade becomes like a microscopic saw. That's why Japanese knives sharpen when cutting. China and Mongolia developed blast furnaces earlier than the West, but from around the 10th century they imported katana from Japan and used it in their armies. China also had swords like longswords and rapiers, but based on katana, Qijiadao, wodao, and miaodao were developed. Chinese Ming Dynasty military scholar Mao Yuanyi (1594-1640) “The katana is extremely strong and sharp, and the Chinese sword is no match for the katana.'' British adventurer Sir Edward Michelbourne (1562-1609) “The Japons are not suffered to land in any port in India (Asia) with weapons; being accounted for a people so desperate and daring, that they are feared in all places where they come .” Spanish trader Bernardino de Avila Giron (- after 1619)"The quality of Japanese steel crushes European steel at the first blow." Around 1970, Japanese steel company Hitachi Metals analyzed and applied tatara and tamahagane to develop Yasugi Specialty Steel (yasugi hagane) and built a sponge iron plant. Yasugi Steel has the same properties as katana, so it is hard, impact-resistant, and hard to break. This special steel is used for various purposes such as cutlery steel, high-end kitchen knife material, razor material(Gillette,Schick,Wilkinson razor steel), automobile parts material, automobile engine parts, and aircraft engine parts. Japanese knives and zwilling Japanese knives are made from steels such as Blue Steel (Aogami) and White Steel (Shirogami) based on Yasugi Steel. Around the 6th century, high-quality iron sand could be mined in the Yasugi region, so it became a town of iron manufacturing. Yasugi City is currently producing Yasugi Specialty Steel at the Hitachi Metals factory and exporting it to the world. Steelmaking engineers at the Hitachi Metals plant learn the traditional tatara ironmaking process. In the 14th century, katana craftsmen migrated to Seki City and produced katana in large quantities. Seki City still produces katana and knives. German knife maker zwilling parsed tamahagane for katana material. zwilling manufactures high-end kitchen knives made from Japanese steel in its Japanese factory.
Modern Japanese kitchen knives are made of several steels namely, aogami the blue steel but also shirogami which is less hard but a bit tougher. Also yes some Japanese knives like the yanagiba are mostly used with pull cuts but a lot of other knives like the Nakiri, gyuto or santoku are often used with push cuts so not sure how realistic the micro serations really are, especially because Japanese knives often have a highly polished edge so I don't think it matters much.
@@Broody58 Vanadium has been detected in 3rd century ironware, according to a survey of ironware in Japanese archaeological sites. Iron sand contains vanadium and iron ore does not contain vanadium. Therefore, it seems that Japan has been using iron sand as the material for iron making since the 3rd century. Japanese iron sand is iron sand that has been weathered by magma. Since there were many volcanoes in Japan, a lot of iron sand can be collected from the mountains. When soil is poured into a waterway, the soil and iron sand are separated by the specific gravity and iron sand can be collected. This method is called kannanagashi. Since the place that used to be kannanagashi was reused as rice terraces, there are still many rice terraces in Japan, and some are preserved as cultural properties.
I enjoyed hearing some of these guys laughing and enjoying themselves; not a frequent sound amongst Japanese professional craftsmen, in my experience. I probably would not have watched the video if I had known I would not see the finished product. This video did not show how a samurai sword is made. It only showed how the samurai blade is made. I would love to see the rest of the build.
Nice to see this without power hammers, belt grinders, welders and no westerner continuously trying to say there is no magic or marvel in the katana. To me, it's pure magic that they figured this all out WITHOUT technology, and complex charts, and lengthy ramblings.
In the first minute they show them hitting a piece of metal. If you do this right, you can actually heat it to red-hot just by hitting it like that. That's how they light the paper.
Great, now we now how to do a blade for a samurai sword :D Thank you fot sharing this phenomenal workflow with us, which combines tradition and presente tech.
The Japanese have been making swords for Millenia, they are proven masters of metal working and fabrication of all kinds. From modern G- 10 knife- steel, all the way back to feudal Japan when Samurai swords were made of "folded- over" laminated steels just as shown in this video. True antique Samurai Swords are made of Tamahagane Steel and they are some of the finest steel ever forged by mankind. It is very satisfying to see this tradition being kept alive by these great blacksmiths, they are all true artisans of the trade and deserve the highest honor and respect for their knowledge. This is truly an ancient art- form and it is satisfying to watch. All the best and much respect from your Pacific "neighbor" California.
exactly! while those fools were out there smoking cannabis and touching breasts, i learned how to wield the blade as though it were an extension of my arm. when the world falls to ruin, let us see who laughs last...
Those lines pressed into that clay is what controls the curve? Marked sword is heated uniformly to that color but during quenching the material under the lines dissipates heat faster than the coated parts... and the side with the base of the triangles radiates it the most... thus contracting asymmetrically and creating the bend? That is... Wait, the blade is already slightly curved just before quenching so... the markings worked already... and in the tank they correct side bends..
How impressive and unique !! The amount of effort and dedication which spent to creat such a master pice is amazing .Respect to the Japanese sword smith .
@@Mmouse_ they’d basically produce the same thing just faster. The Japanese have essentially perfected blade smithing using bloomery steel. ua-cam.com/video/5I6MMbvAWYI/v-deo.html
Thank god for modern metallurgy. It is nice to see old processes because it is entertaining. Most people romanticizes the idea of the way things used to be made, the old world blacksmiths in a dungeon forging Conan's famous sword. lol I respect the old ways but today we have the best of the best in metals for knife making and it is only getting better.
Is this one of those videos where there was actually machinery used? the cuts/edits from rough slag with imperfections to a workable, almost perfect billet, is curious.
That's already smelted steel, albeit not fully liquefied. It's not slag. What they were doing at the start was to make it into a flat piece to then break up into steel chips. It wasn't actually a perfect billet until after they're done with the folding, at which point the levels of carbon and impurities have been dispersed across the billet.
I cannot read what is written, I'm just a lowly bladesmith self taught by current technology available to me using a propane forge. The art and skill handed down from countless generations to make such an amazing tool and weapon is not lost on me. This was a spiritual experience for me having only watched a small portion of this endeavor. Thank you for the upload.
Absolutely amazing that almost the lowest quality starting material possible (Iron sand) can be turned into such an item of exquisit beauty and superlative function by craftsmen of the highest skill. Iron sand is FAR from being the best material to start out with for making a sword, and the whole method of production was / is as of a direct result of the poor quality of that material. It takes special techniques, and all that folding just to get it to the stage where it IS good enough to make a sword. A well made Japanese (Or any other nationality for that matter) blade will last for a thousand years or more, and remain as a fitting tribute to the swordsmith LONG after he's passed from this world!
It's even more impressive when you take in to account that Japanese steel was actually an inferior steel by many standards. True authentic Japanese swords even made the traditional way today require certain care and maintenance that is not generally found in most modern blades. The fact that they are able to make a formidable blade, albeit with certain downsides, is nothing short of absolutely incredible.
Tamahagane isn't inferior. Its high carbon content ore that has to be worked downward in carbon content rather than upwards as with most European ores. Notice theyre barely using flux at all outside the forge weld?
@@joshschneider9766 it's not high carbon content ore it's made from iron sand and the metal is inferior in a way it made for a stronger blade but the metal is more brittle and couldn't hold an edge in battle which is the reason they were constantly in need of sharpening their blades regardless of the metal the durability of a sword comes down to the smith and how many times he wants to fold the metal more layers = more durability
@@OldManLuffy the whole point of a sword is to cut and you can’t do that without an edge. You really think they bee content with such brittle edges for hundreds of years? In reality they had lots of niku on the blade to compensate for the hardness. Brittleness is not just hardness but shape too. Also more folds does not equal higher durability. If you fold the bullet to much you will lose carbon and have a lower carbon blade, therefore a softer blade and therefore a less durable blade. If more folds = more durability then you’d see swords smiths fold their swords way more than they did historically (in the teens)
There is so few videos shows the final cooling of the Katana. It is always forged straight but the final cooling makes it curved because of inner layered metal is flexible but outer one is hardened. Because of that 2 distinct different version of steel it bends itself in the process of cooling. Amazing to think about it. How the hell did they discovered this.
Even more fascinating is how they discovered that the taper simulated movement along the cut like a sawing motion making cutting with curved implements more effective that straight blades.
Like many things probably by accident. Sometimes blades warp in the quenching process and adding clay to it was likely a method to control warping by slowing down how fast it cools, or it could simply had been done to alter its physical properties and had nothing to do with warping, ot to protect the thinner forged edge where rwpid cooling can introduce fatal defects. Either way the effect was the same resulting in a controlled warping that gave a signature to the blade marked by its technique. Whether it makes or superior in any way is subjective as blacksmiths all over the world have found ways to tease out desired properties, and the superiority of the weapons became inter-mixed in mythology and culture, both for self promotion for other nations and for trade. Take for instance some of the legendary blades having 100,000 layers implying thst granted some superior quality to the sword thst allowed it to survive countless battles to be passed down through many generations. That it self is just fluff. Folding homogenises the metal so that you have a mote consistent product that is more predictable and consistent properties all along the blade. Is it necessary to have 100k layers? Absolutely not, five layers is good enough for anything one might use a sword for, and one can achieve 100k layers with around 13ish folds (Im counting with my fingers, give me a break lol). Having 100k layers is just bragging rights.
It looked to me like he forged it at that angle, quenching may enhanced it slightly but you can clearly see the blade was angled before he quenched it. I believe originally the Japanese blade smiths put their own style of Hamon on their blades as we see this in famous Japanese smiths from the early periods had their own signature Hamon.

I can’t stay that clean in a wood shop … amazing!
やはり日本の匠の仕事、海外のナイフ造りとは次元が違います
職人の手がすげぇな
Is this one of those videos where there was actually machinery used? the cuts/edits from rough slag with imperfections to a workable, almost perfect billet, is curious.
That's already smelted steel, albeit not fully liquefied. It's not slag. What they were doing at the start was to make it into a flat piece to then break up into steel chips. It wasn't actually a perfect billet until after they're done with the folding, at which point the levels of carbon and impurities have been dispersed across the billet.
I cannot read what is written, I'm just a lowly bladesmith self taught by current technology available to me using a propane forge. The art and skill handed down from countless generations to make such an amazing tool and weapon is not lost on me. This was a spiritual experience for me having only watched a small portion of this endeavor. Thank you for the upload.
Note when being forged, no power hammers, just arm & hammers!
"This was a spiritual experience..."
Please 🙄
@@chrisdonahue524 also this video is cgi
Make me one of your apprentice i would love to bare your craftsman and art forever in my heart ❤️
Просто невероятная работа, спасибо за видео. Привет из России ✌
Absolutely amazing that almost the lowest quality starting material possible (Iron sand) can be turned into such an item of exquisit beauty and superlative function by craftsmen of the highest skill. Iron sand is FAR from being the best material to start out with for making a sword, and the whole method of production was / is as of a direct result of the poor quality of that material. It takes special techniques, and all that folding just to get it to the stage where it IS good enough to make a sword. A well made Japanese (Or any other nationality for that matter) blade will last for a thousand years or more, and remain as a fitting tribute to the swordsmith LONG after he's passed from this world!
Even with all of today's technology its still amazing to watch skilled craftsmen create things of beauty. Absolutely amazing to watch
It's even more impressive when you take in to account that Japanese steel was actually an inferior steel by many standards. True authentic Japanese swords even made the traditional way today require certain care and maintenance that is not generally found in most modern blades. The fact that they are able to make a formidable blade, albeit with certain downsides, is nothing short of absolutely incredible.
Tamahagane isn't inferior. Its high carbon content ore that has to be worked downward in carbon content rather than upwards as with most European ores. Notice theyre barely using flux at all outside the forge weld?
I'm really really tired of people saying tamahagane is inferior material. Its metallurgically incorrect tosay. Go ask one.
@@joshschneider9766 it's not high carbon content ore it's made from iron sand and the metal is inferior in a way it made for a stronger blade but the metal is more brittle and couldn't hold an edge in battle which is the reason they were constantly in need of sharpening their blades regardless of the metal the durability of a sword comes down to the smith and how many times he wants to fold the metal more layers = more durability
@@OldManLuffy the whole point of a sword is to cut and you can’t do that without an edge. You really think they bee content with such brittle edges for hundreds of years? In reality they had lots of niku on the blade to compensate for the hardness. Brittleness is not just hardness but shape too.
Also more folds does not equal higher durability. If you fold the bullet to much you will lose carbon and have a lower carbon blade, therefore a softer blade and therefore a less durable blade. If more folds = more durability then you’d see swords smiths fold their swords way more than they did historically (in the teens)
He could put electrics on the bellows, but stays with tradition, love it.
The box bellows is a pretty good design already, no need to make it electric.
The secret of the samurai. That was a show that was on about 20 years ago that showed similar scenes of monks mining steel to make samurai swords.
Very nice video but where is part 2 where they finished making the sword?
There is so few videos shows the final cooling of the Katana. It is always forged straight but the final cooling makes it curved because of inner layered metal is flexible but outer one is hardened. Because of that 2 distinct different version of steel it bends itself in the process of cooling. Amazing to think about it. How the hell did they discovered this.
Even more fascinating is how they discovered that the taper simulated movement along the cut like a sawing motion making cutting with curved implements more effective that straight blades.
Like many things probably by accident. Sometimes blades warp in the quenching process and adding clay to it was likely a method to control warping by slowing down how fast it cools, or it could simply had been done to alter its physical properties and had nothing to do with warping, ot to protect the thinner forged edge where rwpid cooling can introduce fatal defects. Either way the effect was the same resulting in a controlled warping that gave a signature to the blade marked by its technique. Whether it makes or superior in any way is subjective as blacksmiths all over the world have found ways to tease out desired properties, and the superiority of the weapons became inter-mixed in mythology and culture, both for self promotion for other nations and for trade.
Take for instance some of the legendary blades having 100,000 layers implying thst granted some superior quality to the sword thst allowed it to survive countless battles to be passed down through many generations. That it self is just fluff. Folding homogenises the metal so that you have a mote consistent product that is more predictable and consistent properties all along the blade. Is it necessary to have 100k layers? Absolutely not, five layers is good enough for anything one might use a sword for, and one can achieve 100k layers with around 13ish folds (Im counting with my fingers, give me a break lol). Having 100k layers is just bragging rights.
It looked to me like he forged it at that angle, quenching may enhanced it slightly but you can clearly see the blade was angled before he quenched it. I believe originally the Japanese blade smiths put their own style of Hamon on their blades as we see this in famous Japanese smiths from the early periods had their own signature Hamon.
Whats amazing to me is that they kept their white gentleman's blouses spotless. I would've covered in soot if it was me.
Amazing, i see that katana curved back while on the water😯
Extraordinary work, brothers!
14:11 is where my favorite part starts! This is where pride and the arts meet. My brain was making templar hymns watching this :)
