Butterfly Knife Case: How to Get a Butterfly Knife Without Opening Cases (2026 Guide)

TL;DR
  • ▸A Butterfly Knife only drops from the Operation Bravo Case, which now costs $40+ per case on the Steam Market.
  • ▸Case opening probabilities are brutal: 0.26% for any knife, and a specific Butterfly Knife finish is 1-in-3,000 chests.
  • ▸CSBoard charges 0% for deposits and direct item-for-item exchanges without money. P2P marketplace sales carry a 2% selling fee. Instant sell is a separate buyout offer; check its quote and the chosen payout method’s fees and timing before confirming.
  • ▸Skip the gamble — buy a Butterfly Knife directly from verified sellers at market prices on CSBoard.
Warning

Operation Bravo Cases are discontinued and expensive. The expected value of opening cases is negative — most players lose money. Buy directly to guarantee the exact knife you want.

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.
