M9 Bayonet 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 M9 Bayonet finishes, gives better odds of a M9 Bayonet specifically:
| Case | M9 Bayonet / gold items | Chance per case | About 1 in |
|---|---|---|---|
| CS:GO Weapon Case | 13 / 65 | 0.052% | 1,923 |
