From the official guides

Link does not possess any weapons at the beginning. In order to attack enemies you must obtain a weapon. If you use your sword you can cause damage to almost all of your enemies. There are three kinds of swords: the regular sword, the white sword and the magical sword. The white sword has twice the power of the regular sword. The magical sword, the most powerful sword of all, is four times as powerful as the regular sword. You can obtain the regular sword rather easily but the white and magical swords are difficult to obtain.
