DISCLAIMER: Make a sword at your own risk! I'm just showing you how I did it--not saying you should follow my methods. I certainly think you should use personal protective equipment (PPE), and follow safe tool use precautions.
I didn't know ANYTHING about making a sword, and I don't claim to know much more now. I know that a real sword is forged and advanced blacksmithing and forging skills are required for creating a real sword.
Mine, on the other hand, is based on a hybrid European two-handed double-edged broadsword made from crappy mild steel (low carbon content), and it isn't tempered or anything. At best, this is purely decorative.
But, it was FUN to make!
That said, I think it could probably at least be stowed away as a weapon to hack up zombies, should some apocalyptic event should occur.
Hope you like it. More videos to come!
