Kusanagi was renamed "Grasscutter Sword" after being pressed into service as a lawnmower
Yeah, forging the legend probably had nothing to do with the whole "can control the bleeding wind" part. The sword was obviously special, even if the moron swiped it without knowing what it can do
In LOTR, we have Bilbo and Sting, and a host of other weapons that were given one name at their forging but another equally famous name by their victims.
The Sting that glows when orcs are near?
Reading at a quick list of the LotR artifacts, just about all of them are magical or special in some regard, if for nothing else then their material. I don't see any +Wambler's Banes+. Notable exceptions like Legolas' long knife which seemingly was only mentioned descriptively, not because people think about it at night. Not that I read the book but the wiki article implies no real fame
Zulfiqar was named "Spinecleaver" after being used to cut someone in half.[/quote]
Gotta give you that one, there's no mention of magic beyond the few people that used it. Largely Mohammad
In Christian mythology, the Holy Spear was just an ordinary spear that happened to get used for stabbing Jesus.
Gotta give you that one too, even if Longinus himself is entirely an imaginary figure
"What? Someone stabbed him!" Well duh but read the story, it's obviously fabricated to suit their agenda. His name probably wasn't even Longinus, that was simply the equivalent of "Jack Smith" in modern english. It's a peculiar myth where the wielder is entirely interchangeable but the weapon attains status from the blood
Got a legend where the weapon in question isn't elevated to artifact status without a (religious) power behind it wishing to immortalize it for propaganda reasons? I don't object to civs naming the weapons of
very notable people to perpetuate hero worship to serve their political agenda but I really don't want to see even damn alligator slayer woodcutter have Incestbellows the Butchery of Slaying, -Bronze Battle Axe-. Killing a megabeast isn't enough in itself to earn a weapon a fancy name, unless you want 12 "Titan Bane"s and 11 "Dragon Slayer"s whenever some kobold bites a Colossus' leg off
TL;DR either the named weapon was already magical or was given a name/invented on the spot specifically so it could be used as a relic by the powers that be. Typically the weapon/item itself isn't even the original, the owner/wielder just
claimed it was to give himself a false sense of importance. That'd be fairly interesting to see in the legends, the dwarven king having a rusty piece of an old hoe reforged into a sword claiming it to be a part of the legendary Lizardbane that struck down a god or another in the age of myth so people would stop mocking his short silky smooth beard
