- "Your room is our "Knife Chamber" on the second floor. This is your room key."
- — Anju
The Knife Chamber is a location from The Legend of Zelda: Majora's Mask. It is one of the rooms of the Stock Pot Inn that are available for rent. Apparently, the room was once used for storing cutlery, but was transformed into a hotel room when the Stock Pot Inn went from being a restaurant to a hotel, though it kept its original name. Though the Knife Chamber plays a minimal role in the story arc of the game, there are some interesting events attached to it. Inside the hotel room is a Treasure Chest that contains a Silver Rupee worth 100 Rupees.
The Knife Chamber can only be entered if Link acquires the Room Key. This can be accomplished if Link talks to Anju between 1:00 p.m. and 4:00 p.m. on the First Day. If Link fails to do this, the Room Key will be given to Link the Goron, and Link will have to wait until that time period in the next three-day cycle to try again. If he attempts to enter the room while Link the Goron is staying inside, Tatl will scold him.
Also, if Link is in the Knife Chamber between 9:30 p.m. and 12:00 a.m. on the Second Day, he can listen through the wall to overhear a conversation between Anju and her mother. Anju's Mother tells Anju that they are leaving for Romani Ranch in the evening of the next day, where Cremia will take them in. Anju wonders if her missing fiancé Kafei will be there, to which her mother responds that if he is there, she will "give him a smack".
Strangely, before Link fully enters the room the weak wall appears to be made of the same texture as walls that can be bombed in The Legend of Zelda: Ocarina of Time. Since Bombs cannot be used inside the Knife Chamber, it is unknown whether or not the wall can be destroyed.
