★ Butterfly Knife | Rust Coat (Well-Worn)

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. This memento from Siege is still perfectly operational although the exterior surfaces have rusted. ★ Butterfly Knife | Rust Coat (Well-Worn) was added to Counter Strike on 3/15/2017 (UTC).
