Razor Sword
From Zelda Wiki, the Zelda encyclopedia
The second sword in Majora's Mask, and it is a good upgrade compared to the Kokiri Sword. It is double bladed, and inflicts much more damage than the first sword. You can forge the very fragile Razor Sword, which is known to break from time to time. Simply visit the Smith in the Mountain Village (you must clear Snowhead Temple first) and they will construct it for you. Beware though, if you do not upgrade it to the Gilded Sword before you have swung this sword 100 times, it will break.
