★ Butterfly Knife | Urban Masked

The Butterfly Knife | Urban Masked is a Covert knife. It comes in five wears, Factory New to Battle-Scarred, with floats from 0.06 to 0.80. It also comes in a StatTrak™ version, but not a Souvenir one. It drops from one case as a rare special item: Operation Breakout Weapon Case.

This is a custom-designed balisong, commonly known as a butterfly knife. The defining characteristic of this weapon is the fan-like opening of a freely pivoting blade, allowing rapid deployment or concealment. As a result, butterfly knives are outlawed in many countries. It has been spray-painted using a tangle of masking tape as a stencil.
