Poacher's Saw
The Poacher's Saw is the fifth item in Ocarina of Time 's trading sequence, which grants you the Biggoron's Sword in the end.
Quest part
To obtain it, Link must have the Odd Potion. He must then travel to the Lost Woods, taking the first left from the entrance, to the place where the Young Punk is located. However, he will only find Fado there, who will tell him that anyone who's not a Kokiri will get lost in the Lost Woods and will become a Stalfos. She will also say that only his saw is left. She will ask Link to give back the Odd Potion, saying it belongs to the woods [1], and will give him the Poacher's Saw in return (the one the Young Punk left behind). Link must then give the saw to Mutoh, the boss of the Carpenters, who will be standing on the far side of the Gerudo Valley. If Link has already rescued the carpenters, the bridge will be built, otherwise he must either use the Longshot or jump with Epona [2]. He must then give the saw to Mutoh, who will give him the Broken Goron's Sword in return, saying he wanted to go to the town to have it fixed but it's not much use to him anyway [3].
