Youtube channel where a welder documents himself as he builds giant anime swords for people who pay him money. I find his accent and his work mesmerizing. Very calming and easy to watch while doing something else. I found a video randomly, and 2 hours later I realized I had watched the whole thing.
He's not a blacksmith. He takes pieces of scrap steel, and he welds and grinds to make it all fit. He also routinely picks up blazing hot pieces of metal with his gloved hands; complains that it's hot and burning him... and then picks it up again.
