Nostalgia has hit me, and I have dusted off my old Super Nintendo which luckily still works, and popped in my Final Fantasy II cartridge which also still works! I remember as a kid, there was a way to split a weapon by doing something with it in your inventory during a battle, then running away. It allowed you to create an infinite number of copies, even for weapons that were "unique" in the world, such as the crystal sword, or Edge's Masamune.
This was a cheap way to get some gold by selling duplicate copies of powerful weapons. It was also very useful in providing Edge the Ninja with an unlimited supply of very powerful throwing weapons.
Does anyone remember this trick and how to do it on the SNES version of Final Fantasy II?
Keep in mind, this would have been technically Final Fantasy IV in Japan, but was released at the time as FFII in the U.S. as it was the 2nd U.S. release in the series.

Taken from the FF Wiki:
The original SNES version of Final Fantasy IV (Final Fantasy II in North America) and its PS1 ports contain a simple exploit that allows the player to duplicate any item that can be equipped in either hand.
Each character that begins the battle can use this bug to duplicate the items in both hands, but it works only once per battle, and only with the items equipped when the battle begins.
This bug could be exploited to multiply unique weapons like the Crystal Sword or Gungnir spear, making them practical as ammunition for Edge's Throw command. This would also allow Edge to equip two Masamunes.
This glitch does not work on arrows.
