Yeah, I’ve tripped over that one in a few villages. It turns out the “blade” isn’t a super‑sword at all but a special copper alloy that glows under moonlight, and the dragon part is more a ritual trick than literal cutting. The warriors just love to spin it because it’s a neat story about taming the untamed. So the real legend is a mix of metallurgy, moon‑rituals and a bit of bravado, not a blade that literally slices a dragon’s hide.
