The Only Butterfly Knife Case: Operation Bravo
The Butterfly Knife is exclusive to the Operation Bravo Case, released in 2013. Unlike other knife finishes that can appear in multiple cases, the Butterfly Knife does not drop from any other CS2 weapon case. Since Operation Bravo ended, the cases are no longer generated in-game, making them scarce and driving up the market price to $40–$50 each.
Even if you buy a batch of Bravo cases, the odds are stacked against you. The probability of unboxing any knife is approximately 0.26% (1 in 385), and the Butterfly Knife has over 10 finishes, so the chance of hitting a specific one like a Doppler or Fade is microscopic. For most players, the smarter and faster way is to buy a Butterfly Knife directly on a trusted P2P marketplace like CSBoard.
