Butterfly Knife odds per case
In every official case the chance of a rare special item is 0.26%, about 1 in 385. That chance is shared between all the gold items in the case, so a case with fewer gold items, or more Butterfly Knife finishes, gives better odds of a Butterfly Knife specifically:
| Case | Butterfly Knife / gold items | Chance per case | About 1 in |
|---|---|---|---|
| Operation Breakout Weapon Case | 13 / 13 | 0.260% | 385 |
| Spectrum Case | 6 / 30 | 0.052% | 1,923 |
| Spectrum 2 Case | 6 / 30 | 0.052% | 1,923 |
| Operation Riptide Case | 6 / 30 | 0.052% | 1,923 |
| Dreams & Nightmares Case | 6 / 30 | 0.052% | 1,923 |
Assumes every gold item in a case is equally likely, as in our simulator. Valve only publishes the odds per rarity.
