Giant's Knife

The Giant's Knife is an incredible durable item that does twice as much damage as the Master Sword.

How to get it

First of all you will need two hundred Rupees, which you need the Adult's Wallet. Now if you have these things go over to Goron City. Once you enter go down to the second level where there are some bombable walls. Blow them up with the Bomb Flowers close by, or use your own bombs. You will then find a Goron called MediGoron selling the Giant's Knife. Buy it, you will find out that it uses two hands, so you can't use your shield. Also it will break after hitting an enemy or the wall a few times. Follow the guide for the Biggoron Sword side quest if you want to make this item invincible.
