Play the game all the way until you reach the final battle with Ganon. After you lose your Master Sword, perform the Play things like ocarinas / drink milk from them glitch to play an Ocarina (you usually aren't able to). Play the Sun's Song, and the battle will reset to after the destruction of the castle. Go forward and start the battle, losing your Master Sword AGAIN. Now do the above glitch once more, but play a warp song. Now you can save your game, and the Master Sword will stay unequipped. Then, you can wander around and discover the interesting side effects that occur without your sword.
