The Festivizer allows the user to Festivize either a Decorated weapon or a few other select weapons. Applying a Festivizer to an eligible weapon wraps it with a coil of flashing yellow, green, and team-colored Christmas lights, in a similar fashion to Festive weapons. A weapon retains its current quality when Festivized (e.g. a Strange Minigun would remain in Strange quality after the tool is used). However, when applied to Stock weapons, they are converted from Normal quality to Unique quality. Applying a Festivizer also adds the prefix "Festivized" to the front of a weapon's name, changes its backpack icon to reflect its new in-game appearance (wrapped with festive lights), and adds "Festivized" in purple text to the weapon's description.
