Basically, it is a leaf spring used in trains and automobiles, so it is the highest quality carbon steel. It is a high-strength carbon steel that is incomparable to old steel. These days, people were very fond of old-style Japanese swords a few years ago, but these days it's different. This is because people realized that the steel made by the modern iron manufacturing method has superior elasticity and rigidity than the old iron material. The old-fashioned folding method was used because the basic quality of traditional Japanese iron was very poor. However, in the case of the highest quality carbon steel in which impurities have been removed down to the decimal point by modern steel manufacturing methods, such a welding method may not be necessary.
Iron sand in Japan is iron sand that magma has weathered. This iron sand has low phosphorus and sulfur content and contains vanadium. Phosphorus and sulfur make steel brittle, and vanadium strengthens it. 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. th-cam.com/users/shortsTldpPYewaQo 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. 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. Japan's Hitachi Metals developed Yasugi Specialty Steel (yasugi hagane) around 1970 by analyzing and applying tatara ironmaking and tamahagane. 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 Paper Steel (Aogami) and White Steel (Shirogami) based on Yasugi Steel.
wonderfull blade, shorter for more maneuvrability (the way i like it) yet thicker to compensate for loss of cutting power, beautifull blade geometry, tastefull finitions... 9.5/10
Absolutely brilliant! I love your approach to this - I can see your woodworker/maker experience in it. When you went in with that rotary polisher - I just smiled thinking that these are my people (woodworkers can make anything 😊)
This reminds me of some of the people on forged in fire show when they go home to make a sword they just get a piece of metal that’s roughly the same shape and they heat it up and straighten it by hitting it with a hammer a couple times then they just cut it to the shape they want or they grind it then they harden it and put a handle on it imo that ain’t the right way of knife making you should make it from a billet and hammer it to shape you want hell just about anyone can do it this way ☝🏻
Interesting sword. I'm not hating on this, but I wouldn't exactly call this a katana. Yes, it has the general shape of one and, yes it has a makugi pin, but it's much too thick. Katanas also have a slight distal taper allowing them to be more effective cutting and slashing weapons. This sword closer resembles a falchion or a broad saber. Again, not trying to hate. Love the build, beautiful blade. Well done.
Bro. Tamahagane IS pure shit. Spring Steel is really good for making katanas. However for japanese government that's not a katana because not made from tamahagane and not by a Japanese sword smith. But it's a single edge sword with a 60cm or plus blade length. It's technically a katana. And no sword on hearth can slice a steel helmet made for war.
For Japanese government no. For us yes, it's a single edge sword with 60cm or plus of blade length. It's technically a katana and tamahagane is not good and expensive and really hard for get a good sword. Relax it's technically a katana
This is a sword-shaped knife. Because there is no process to make Katana. It is an insult to us Japanese without understanding the structure of the sword at all. I don't want you to call such a fake a Katana.
Not a real katana the katana is made from ore of iron from soft and hard iron tamahagni and urangi ur gaurd needs to be more widened out ur soba is off by a fraction of a hair and ur handle need to be 2 handed not 1 handed what u just made was a Roian sword with a katana style .
Single edge sword with 60cm or plus blade length. It's a katana don't be silly like that. Tamahagane is pure shit with waaaay too much carbon. Spring Steel is a really good and cheap deal
Моя мрія життя.. Мати справжню таку Катану.. Дуже мочну і дуже гостру.. Ви виготовляєте їх на замовлення чи як? 🤔 Я незнаю чи вистачить грошей в мене на неї..(( Я був би радий такому Подарунку) 😊 Ви звідки? Напишите мені будьласка.. Однозначно Рекомендую ВСІМ Відео і ВПОДОБАЙКА 👍

And an old spring has been used and abused for years and may develop micro cracks that can cause the sword to break.
Is there anything you can't do? A simple "wow!" from Germany
Bismillah ma sha Allah very ver nice
very nice but most people missed the "out of rusted a spring" on the title is it supposed to be "out of a rusted spring" 😄

Huuuuuyyyyyyyyyyyyiiii q bien si quedan resistente desde Colombia
Como se faz pra ela não enferrujar?
Question: when you heat treated the blade, do you know how hot the blade actually got?

旧日本軍の一部兵士は板バネから作った軍刀を愛用していたと聞いたことが有ります。
小銃が支給される一般兵士と違って士官の軍刀と拳銃は個人の持ち物だったとかで。

Isn't it supposed to go all the way into the handle, like the whole length of the blade should extend into the handle to the bottom
Iam making swords from Japanese spring steel, from an old Nissan.
Which material do u use, boss
super!!!
Nice! Are you waiting the invaders?
tempered... but not normalized? thats gonna be brittle as f**k!
All in all, a respectable Katana style weapon, though the missing element means 8/10 😁

very good forge indeed! but i think the grip is too small to block the attack on swordman's wrist

How the fuck do you know 😂😂😂 and katana are limited in length not in weight

And why ? Because no tamahagane?
Ну и терпения у тебя , самурай 👍💪
