Butterfly Knife | Doppler

The Butterfly Knife | Doppler is one of the most recognized and sought-after knife finishes in Counter-Strike 2. It belongs to the Doppler family, known for vivid, shifting color patterns that make each finish look distinct. In CS2, this skin uses the modern CS2 model presentation, keeping the iconic butterfly silhouette while highlighting the Doppler’s prismatic visual style.

As a Covert rarity weapon skin, the Butterfly Knife | Doppler is considered high-tier and typically harder to acquire than lower-rarity options. While exact drop rates are not publicly guaranteed for specific knives, Covert knives are generally restricted to rarer outcomes in case openings. The float range of 0–0.08 also helps define which wear tiers are possible, with the most visually pristine versions landing at the lowest floats.

You can find the Butterfly Knife | Doppler in the following supported versions: Factory New and Minimal Wear. StatTrak is available (Yes), allowing players to track kills with this knife. Souvenir is not available (No), and there are no collections listed for this specific item. The skin’s technical details include paint index 418, which corresponds to how the finish is mapped within the game’s item system.

Visually, the Doppler finish is defined by fast-changing-looking bands and gradients of color that vary with the knife’s pattern and wear. This is what gives the Butterfly Knife | Doppler its “alive” look—shifting tones under different lighting and camera angles. Because the skin is pattern-based, no two instances are guaranteed to match perfectly, which adds to its collectability.

For acquisition, this skin is found in Spectrum Case and Spectrum 2 Case. These case sources are the primary in-game path for players looking to open for the knife, with availability depending on the current market and case drop ecosystem. (Note: the knife is not listed as being found in any other collections.)

In the community, the Butterfly Knife | Doppler is widely regarded as both a prestige and aesthetic choice. Its combination of a classic knife shape, Covert rarity, and the Doppler’s striking color play makes it a popular centerpiece for avatars, plays, and loadouts—especially among players who value standout visuals and high-demand skins.
