★ Butterfly Knife | Doppler

The Butterfly Knife | Doppler is a Covert knife. It comes in two wears, Factory New to Minimal Wear, with floats from 0.00 to 0.08. It has seven phases, each a different look: Black Pearl, Phase 1, Phase 2, Phase 3, Phase 4, Ruby and Sapphire. It also comes in a StatTrak™ version, but not a Souvenir one. It drops from two cases as a rare special item: Spectrum Case and Spectrum 2 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 painted with black and silver metallic paints using a marbleizing medium, then candy coated.
