What is the drop rate for a butterfly knife in the Operation Breakout Weapon Case?

Since the rare special tier holds nothing else, the butterfly rate and the knife rate are the same: 0.3% of opens, below the 0.6% of the covert pair. A finish is picked only after that tier comes up, so any single version drops less often than the tier figure.
