About the Butterfly Knife | Urban Masked
Butterfly Knife | Urban Masked is a Rare Special Item knife that drops from one of the 42 CS2 weapon cases, the Operation Breakout Weapon Case.
Valve released the Operation Breakout Weapon Case on 1 July 2014.
Each open has a 0.0200% chance (about 1 in 5,000) of pulling it, as one of 13 Rare Special Item finishes. One in ten of those drops is StatTrak.
It sits in tier 5 of 5 (Mil-Spec to Rare Special) and ranks #13 of 27 finishes in the Operation Breakout Weapon Case by top-wear Steam price.
Its Steam price runs from $601.48 to $663.38 across wears, against $13.26 to open the Operation Breakout Weapon Case (case plus $2.50 key), so every wear is worth more than one open.
