StatTrak™ Flip Knife | Doppler (Factory New)

The Flip Knife | Doppler is one of Counter-Strike 2’s most recognizable knife variants, built around the celebrated Doppler finish. While knives and Doppler patterns have appeared in the game ecosystem for years, the CS2 model keeps the same iconic identity: a highly reflective, color-shifting surface designed to look different under varying lighting and viewing angles. The result is a knife skin that stands out instantly in both screenshots and live gameplay.

As a Covert rarity item, the Flip Knife | Doppler is considered extremely desirable. Covert knives are typically far rarer than common weapon finishes, and their drop rates are closely tied to the overall chance structure of knife case drops and related rarity tables. Specific odds aren’t reliably published for every scenario, but the community generally treats Covert knives as low-frequency pulls, especially in higher-demand cases.

This skin supports multiple versions to match player preferences. The available wears are Factory New and Minimal Wear, with a float range of 0 to 0.08, keeping the surface quality in the best-performing visual bracket. StatTrak is available, allowing kills to be tracked on the weapon. A Souvenir version is not available, and there are no known “collection” listings associated with this item on the page level—its primary relevance comes from its case presence.

Visually, the Doppler finish is defined by prismatic, moving-looking color bands that resemble a “phased” or rotating color pattern. This particular variant uses paint index 417 and is modeled for CS2, giving it a crisp, high-contrast look compared to many other knife finishes. The “Flip Knife” form factor further amplifies the effect—when you inspect or move with the blade, the Doppler pattern can read as shifting between vivid hues.

To obtain the Flip Knife | Doppler, look for it in the Chroma weapon case ecosystem. It can be found in the Chroma Case, Chroma 2 Case, and Chroma 3 Case. Since knife skins are only obtainable through these case drop systems (or through player trading, depending on your marketplace preferences), your path to ownership typically involves either opening eligible cases or buying from other players.

Community perception of the Flip Knife | Doppler is overwhelmingly positive. It’s widely regarded as a “collector-level” knife due to its iconic finish, the popularity of the Flip Knife animation, and its consistent presence among top-tier knife skins. For many players, it’s not just about rarity—it’s about the look, the inspect appeal, and the way the Doppler colors draw attention during gameplay.
