Forging a MACHATANA out of Old Concrete Iron

[EN] Forging a MACHATANA out of Old Concrete Iron
In this video, I show you how I forge a machatana. I chose to make a sandwich out of old 15N20 rebar and the blade core out of high-carbon rail. I had a lot of fun forging this Katana, which has a very particular style... I love the blade with its nickel line that makes super waves, the cutting edge has a high carbon content and cuts like a razor. I love giving new life to old scrap metal by transforming it into a beautiful object! I've learned a lot forging this great Katana, and I hope you'll learn as much as I did when you watch the video!
Do not hesitate to leave me comments. See you soon for a new knife project!

[FR] Forger un MACHATANA à partir de vieux fer à béton
Dans cette vidéo, je vous montre comment je forge un Machatana. J’ai choisi de faire un sandwich avec un vieux fer a béton du 15N20 et l’âme de la lame en rail de chemin de fer de haute teneur en carbone. Je me suis bien amusé à forger ce Katana qui a un Style bien particulier… J’adore la lame avec sa ligne de nickel qui fait des super vague, le tranchant a une haute teneur en carbone et il coupe comme un rasoir. J’adore redonner vie à des vieux bouts de ferraille en les transformant en objet magnifique ! J'ai beaucoup appris en forgeant ce super Katana et j'espère que vous en apprendrez autant que moi lorsque vous regarderez la vidéo !
N'hésitez pas à me laisser des commentaires. A bientôt pour un nouveau projet de couteau !

first time watcher, now subbed. I love the way you could see the heat soak out of the metal when the hydraulic press was giving it the first few rounds of squidging. quick question though, when you were using the dremmel type rotary thing on the edge, why was the metal turning milky? I'm guessing heat, but it looked like frost! Awesome job btw. Finished article looked immense.

[@boulderdashforge]

thank you very much 🙏 the white color comes from the fact that I had put a shot of iron perchloride on it when heated it becomes white.

Ho avuto questo grosso tondo per un po' e non sapevo davvero come usarlo... quindi ho avuto questa idea 💡il tondo è abbastanza flessibile e l'interno è in ferro, questo dà una lama flessibile con un filo molto duro

[@kidedk]

I like the video lots there is just one problem you did not use a lubricant when you drilled the holes where the handle was going to go so the drill bits were burning and causing the smoke because of the friction 😢

Before sharpening, you should have leveled and corrected the edges, and later on, you should increase the sharpness of Damascus steel with several steps, so that this beautiful work can be compared with the best despite all this effort.

[@boulderdashforge]

ok I'll try that, do you have a video to recommend so I can see that?

[@realgallantful]

@@boulderdashforge I recommend that you bring the blade to the peak of the edge correction before the hardening process, and using the Japanese method and creating more carbon on the edge and protecting the back of the blade from carbonization and more heat, create a spring texture that can withstand impact. The same sharpness and smoothness to spread the wave resulting from the blows along the length of the blade and prevent the blade from breaking. For this purpose, the Japanese use the center of the blade from soft steel and the sides from steel with extremely hard capabilities. In front of the impact, it looks great, but since you don't have the necessary materials to imitate the Japanese blade, or it may be expensive, so you have to do it with alloy steels, so that the normal texture in the middle and the steels Use the sides from the order of alloy steel, with this the result will be almost the same, but you need to allocate more time to correct the edges and use the manual method so that the blade does not suffer from spot burns and is resistant to impact. It requires a lot of trial and error to be able to create an excellent and high-quality Damascus blade, but the result will be really wonderful, as a result, you will have a blade that cuts the bone like a cutter.
