You can use this sword to clear away the large rocks that protect the Super crop field behind the waterfall. To use the sword to destroy the rocks, place it in the red slot in your rucksack then press the A button. You will swing the sword and the giant rocks will go away. The sword's main use is just for destroying the large rocks. You can also use it to fight off the creatures in the mines if you equip it and press the Y button. If not, you can just store it inside your house once you're finished with it.
It can be used to cut weeds or defeat the evil monsters in the mines. If you press the 'A' button in front of the rocks either side of the waterfall it will smash the rocks.
To get the sword, you have to reach the bottom of the second mine. On the last floor, you have to destroy all of the monsters to make the big rock blocking your way disappear. In that room will be the Legendary Sword.
Behind the waterfall near the mines. You can access it by unlocking the 2nd mine, and getting to the last level. Then, you can either get a sword, or wake up the lady. If you get the sword, you can break the huge rocks that are blocking the path to the cave.

The Sword is mainly for unlocking the special field behind the Waterfall. After that it is only good for fighting monsters while in the mine.
You must get the Legendary Sword, equip it, and press the A button while standing in front of the boulder blocking the path. The Sword is at the bottom of the second mine (there are 255 floors). Once you get to the bottom floor defeat all the monsters and you will gain entrance to the Sword room. You will not be able to pick up the Sword unless all your Tools are upgraded to Mystril.
