Razor Sword (The Legend of Zelda: Majora’s Mask)
Ah, the Razor Sword. Perhaps one of the greatest disappointments in Zelda history. The Razor Sword’s design is surprisingly excellent and makes it only more disappointing when you realize how useless it is. You can get your Kokiri Sword upgraded at the Snowhead Blacksmith for 100 Rupees, leaving it with them for an entire day to be reforged. After that, you get the badass Razor Sword! …But only for a little while.
After 100 blows, the Razor Sword’s blade dulls and turns back into the Kokiri Sword. Not only this but if you go rewind time back to the Dawn of the First Day, it reverts back to the Kokiri Sword anyway. Such potential, lost in a high cost and a limited use. At least you’re guaranteed to see it once by upgrading it to its much superior older brother, the Gilded Sword.
