About the Butterfly Knife Ultraviolet

The ★ Butterfly Knife | Ultraviolet was added in March 2017.

“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 individual parts spray-painted solid colors in a black and purple color scheme.”
“Elegant design paired with brutal intent”
