Butterfly Knife Skins

Weapon skins were introduced to Counter-Strike with CS:GO's Arms Deal update in August 2013, which brought Cases, the Steam Community Market, and the first tradable weapon finishes to the game. The earliest Butterfly Knife finish with a confirmed release date tracked on CS2Owl is Butterfly Knife from Operation Breakout Weapon, released on July 1, 2014. Since then, the Butterfly Knife skin lineup has grown to 35 skins, with 35 available in StatTrak™ versions and none currently available as a Souvenir edition.

Early finishes were plain, single-pattern designs. Later Cases introduced layered, custom-illustrated artwork and textured finishes, expanding what a weapon skin could look like well beyond a solid color or simple camo.

When Valve relaunched the game as Counter-Strike 2 on September 27, 2023, every existing Butterfly Knife finish carried over unchanged onto the new engine, and new finishes have kept releasing through CS2's own Cases and Collections since.
