Every pull is graded like a collectible card: tier, wear, float and pattern sealed on a slab. Classified and rarer pulls get a foil.
Operation Breakout Weapon Case
Every item in the rare special tier of the Operation Breakout Weapon Case is a butterfly knife: 13 versions, from the plain ★ Butterfly Knife, which has no finish at all, to ★ Butterfly Knife | Fade and ★ Butterfly Knife | Slaughter. No other knife type drops from it.
The weapon side holds 14 skins. P90 | Asiimov and M4A1-S | Cyrex are the covert pair, the rarest weapon skins in the case, while Glock-18 | Water Elemental and Desert Eagle | Conspiracy sit in the classified tier. The case has StatTrak versions.
Mil-spec skins such as SSG 08 | Abyss and P2000 | Ivory take 79.9% of opens, and restricted skins take 16%.

Questions
- What is the Operation Breakout Weapon Case and what does it contain?
- It is a CS2 weapon case with mil-spec, restricted, classified and covert skins and a rare special tier made of butterfly knives. A classified skin drops on 3.2% of opens, and Five-SeveN | Fowl Play completes that tier. Each open gives one item.
- What butterfly knife finishes are in the Operation Breakout Weapon Case?
- Apart from the plain knife, the butterfly pool comes in these finishes: ★ Butterfly Knife | Fade, ★ Butterfly Knife | Slaughter, ★ Butterfly Knife | Crimson Web, ★ Butterfly Knife | Case Hardened, ★ Butterfly Knife | Blue Steel, ★ Butterfly Knife | Night, ★ Butterfly Knife | Stained, ★ Butterfly Knife | Scorched, ★ Butterfly Knife | Boreal Forest, ★ Butterfly Knife | Forest DDPAT, ★ Butterfly Knife | Safari Mesh and ★ Butterfly Knife | Urban Masked. No gloves share the tier with them.
- 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.
- What skins are inside the Operation Breakout Weapon Case?
- The restricted tier holds CZ75-Auto | Tigris, Nova | Koi, P250 | Supernova and PP-Bizon | Osiris. The mil-spec tier adds MP7 | Urban Hazard, Negev | Desert-Strike and UMP-45 | Labyrinth to SSG 08 | Abyss and P2000 | Ivory, which completes the weapon skins below the classified tier.
- When was the Operation Breakout Weapon Case released?
- The Operation Breakout Weapon Case was released on July 1, 2014. At the top of its weapon skins sit P90 | Asiimov and M4A1-S | Cyrex at covert, and its rare special tier of butterfly knives includes finishes such as ★ Butterfly Knife | Crimson Web and ★ Butterfly Knife | Case Hardened.
