StatTrak™ Butterfly Knife | Doppler (Minimal Wear)
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.

Description
The Butterfly Knife | Doppler is a long-standing favorite in CS weapon skins, and in CS2 it continues to showcase its iconic, high-contrast color play. As a Doppler-finish variant, it’s known for the vivid “animated-like” visual effect that comes from the way the pattern and materials render across the blade. The skin is often sought after by players who want a classic rare look with modern CS2 presentation.
With Covert rarity, this skin is considered one of the more premium categories in the game’s drop pool. While Valve does not publish exact drop rates publicly, Covert-class items are generally uncommon and are typically obtained through case openings rather than frequent in-game acquisition. Because of its rarity and popularity, it tends to draw strong demand from collectors and high-visibility weapon buyers.
You can find the Butterfly Knife | Doppler in Float values from 0 to 0.08, with available wears including Factory New and Minimal Wear. StatTrak is available (Yes), letting you track eliminations with the knife. A Souvenir version is not available, and there are no confirmed appearances in any specific collections for this skin listing.
Visually, the Doppler finish is defined by its shifting spectral tones and striking blade patterning. This page refers to the CS2 model with Paint index: 618, which is used internally to identify the exact pattern/material setup. In practice, the result is a bold, premium look that stands out in both gameplay and screenshots—especially on the Butterfly Knife’s reflective, symmetrical silhouette.
To obtain the skin, look for it in these containers: Spectrum Case and Spectrum 2 Case. As with other case-weapon skins, availability depends on case drops and openable inventory sources, so supply can vary over time—often influencing how often the skin appears in the market ecosystem.
The Butterfly Knife | Doppler is widely regarded as a “must-have” among knife enthusiasts and a benchmark for Doppler-style finishes. Community perception remains consistently positive due to its iconic reputation, the Covert rarity tier, and the strong visual impact it delivers in CS2.
