- "Wielding a katana will grant the wielder incredible powers of leaping. Always place the pointy end into a Tediz."

The Katana is a weapon used by Conker in the ending of Conker's Bad Fur Day and its Xbox remake, Conker: Live & Reloaded. Its main role is in Bad Fur Day's Multi mode, where it is used as a cutting weapon.
By wielding a Katana, the player's moveset changes to that of a samurai's. This includes the abilities of: withstanding the fall from greater heights, jumping higher, and running twice as fast than normal. Characters with a Katana are absent from the radar. By pressing , the player can make his or her character draw or holster the Katana. The button makes the character swing the Katana. When the player's character swings the Katana at an opponent, he or she does a front-flip jump and thrusts the sword into the opponent's head. The character sometimes makes a ninja-like yell. If the player presses another time, the character slices its opponent's head off.
In the end of Bad Fur Day, Conker struggles to defeat Heinrich, and the game locks up. He communicates to a Programmer and requests to choose from a selection of weapons. Conker decides on a Katana, which he uses to slice off Heinrich's head.
