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.
Introduced in the Gamma Case in 2015, the Gamma Doppler pattern is similar to the Doppler but with a distinct color scheme and more vibrant swirl effects.
The blade displays a vibrant mix of green, yellow, and purple hues with a swirling pattern, complemented by a black handle with metallic accents.
Gamma Doppler is popular for its vivid colors and dynamic appearance, making it a desirable skin among players and collectors alike.
