Dope Tech Episode 2

<<@MohammedBangou says : european medieval great swords be like>> <<@nickw3255 says : I'm surprised they didn't mention this, but this special steel is called tamahagane>> <<@SlishSlosh says : Am i able to buy one of these swords? I want an art piece but i also want to make sure that extreme love and care went into making it.>> <<@mnoorist8223 says : what is a katana? it is a japanese sword>> <<@cjb110 says : If we had to build a sword now, with all our modern understanding and techniques, what would we use?>> <<@jaylanblake2610 says : This only works using black sand from certain areas. The variety's of mineral in black sands depends heavily on local geology. Iron is normally still the most common, other minerals contain, lead, tin, manganese as well as others. I imagine you'd get different quality steel from different drainage basins. In modern times magnetic separation is awesome. Note not all the iron will be attracted, some loss but more pure>> <<@mohammad.p.r2920 says : Is there any way to buy these swords online?>> <<@redmondpeters6221 says : Japanese swordsmiths didn't make instruments of death they made WORKS OF ART.>> <<@pauliussipavicius4658 says : What are you talking about, go ask any actual swords expert, japanese swords were inferior and easilly shatered in a fight against european swords if they clashed. Katanas literally were made for unarmored(or almost) combat, because the moment you actually defend against it, it becomes garbage.>> <<@funkmasternasty says : This guys incompetence is driving me insnane.😂>> <<@Tec-h6x says : Holy cow is this a free video>> <<@1lemn says : the sword that zoro uses>> <<@skeletongamer_1743 says : Hamon sounds pretty bizzare>> <<@enderkavrar1 says : Use the correct map of Türkiye. Showing inaccurate borders representations is misleading and disrespectful.>> <<@Thedaythedaysend says : MADE IN JAPAN>> <<@joetheperformer says : These Japanese blacksmiths were actually alchemists. They were dealing with precise molecular chemistry before molecular chemistry was even invented. That is crazy.>> <<@omparkash-c3y8w says : Great tips, thanks for sharing!>> <<@Sasser2015 says : The fact that they figured all this out without the molecular/atomic scientific knowledge of today blows the mind.>> <<@ilovesilksong says : I understood everything>> <<@j.Porkbelly says : They were making carbon nanotubes.>> <<@DuncanFraser-o4n says : miyamoto musashi fought in over 60 duels to the death and won every last one of them, just as well or there wouldn't be much of a story about him!>> <<@arroyoruy says : Dude, Kevin Cashen is out of focus. how can anyone watch this?>> <<@Rick-t5b8o says : I'm very confused that 3000 years ago that they know all the science about how to make a sword.>> <<@Anna-ii3ee says : Fantastic video! Gives me more appreciation for the katana I was gifted.>> <<@letthetunesflow says : I’m sorry but Bronze can hold A good edge for far longer than most realize… Iron is much more abundant which made its other drawbacks worth it over bronze, but traditional Iron had its own drawbacks and bad Iron was actually often far worse than a great bronze sword… Bronze is far better than we now give it credit for, and switching to iron was done not just because it was “better” but because bronze was far more expensive with tin being extremely rare, and when/if trade ever was interrupted it proved to be impossible to make anymore bronze, so even when the first iron swords were of worse quality, the fact that iron ore is found almost everywhere made it worth switching to over bronze, even when the first iron tools and swords had major drawbacks, often shattering/breaking, with the first iron tools and swords being actually less durable, prone to contamination, flaws, and having difficulty with controlling its hardness… So yeah, iron at first was of worse quality, but the issue was its rarity and cost, which made the drawbacks of the first iron worth dealing with… It would take centuries before iron working techniques caught up to Bronze… Bronze could be hardened and hold a fantastic edge while also being far more durable, and corrosion resistant… Don’t believe the story that Iron was instantly superior!>> <<@FranksThink says : Cool video — amazing! keep it up 😁.>> <<@kanishkasampath2832 says : The Tamil people taught the Japanese how to do this . Dig in to Damascus blades , ocean going Tamil people and you will have a answer :)>> <<@fromaggiovagiola9128 says : It's facinating how sub-Saharan Africans invented this too.>> <<@PaulMcCartExperience says : 15:14 no eye protection?>> <<@DEVILCANSEEU says : the second i heard hien period my mind got flashbanged with sukunas face....idk why o-o>> <<@Dîkkü_8 says : The sword getting it's curve shape due to the formation of MARTENSITE is just so cool. It's like the Katana was destined to be curved. Science and Universe is crazy.>> <<@riansteward5163 says : hamon?>> <<@cjvilleneuve1566 says : The Japanese culture is beyond awesome, they are truly our master maker on earth.>> <<@kimchristiansen7886 says : 🤔 Would it make a difference, to cool the blade in a 15 meter long, 30 cm wide, 45 cm deep watertray, with a 15 meter long, 1.8 cm thick ice rail, at the bottom of the watertray. Then lower the blade to the icerail, and then drag it at a step pace, of frontal attack at 30 chops, and drop the drag at end, and let it finish cool🤔 Inspiration to Music " Bloodrayne 2 Soundtrack " 🙏🎶❤️❤️🎶🙏GOOD FOCUS HONESTY🙏🎶❤️>> <<@Vataf-c says : Every sword made for combat can slice bullet not ONLY katana>> <<@PremanthkumarShekaramahanthi says : I guess quenching is done with oil .....>> <<@Mini-c137 says : skyforge steel is the best>> <<@GG-od2tr says : The master always looking for the last apprentice.>> <<@venisontron says : Bro every dude around that kiln is wearing a mask except you>> <<@Antimemetic says : 18:21 minor spelling mistake :3>> <<@mromatic17 says : i would love to do this! the japanese are better than us.>> <<@ALVMACHETE69 says : It's a true work of art. And very spiritual 🎉 bravo 👏😺😺😺. Done like share and subs to you and all.>> <<@Zoe.Babalon says : 25:17 so neat, a guy in a full beard explaing about the less irritation one blade brand. When did you use it last?>> <<@olddudegaming68 says : Need to say after some years on YouTube this video is the first I need to say it was worth every second I was watching thank you.>> <<@inaidikai9509 says : Seeing sword making is my biggest joy of life>> <<@kurokurokuro172 says : Strong and sharp enough to slice a bullet in half Like a butter knife? Cuz a butter knife can do that. Everyone, this is a misunderstanding. It's something that an extraordinary samurai cuts with their incredible reflexes and skill. Can you yourself cut a bullet flying towards you? That's the question. And then it's become a case of "if it's a sword, you can cut bullets.">> <<@OvidiuCotrus-z5n says : Katana Isaac police 🚓 mafia>> <<@erinharkiewicz7239 says : This… is … the greatest video ever. I feel like I am not even worthy to watch it.>> <<@Skelter13th says : Hatori⚔️Hanzo>> <<@Ou812IC71 says : Enemies war armor and chainmail! The katana natural groove is actually originally intended in design. 5th century. It was curved so that it could be trusted upward piercing armor killing the bird of the armor! Do not waste your blade striking at chainmail. Look for the vulnerable spots of flesh kill instantly!! The samurai were not barbaric! They are precision warriors! Thank you! So for all you who say the curve of the blade it was developed long before to f****** get under armour that is why the katana has a natural bend!>>
