About the Butterfly Knife Gamma Doppler
The ★ Butterfly Knife | Gamma Doppler was added in September 2021.
“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.”
