StatTrak™ ★ Butterfly Knife | Gamma Doppler Phase 1 (Factory New) is a show-stopping flipper from the Operation Riptide Case, added in September 2021. This Butterfly Knife has been finished in an Anodized Multicolored style with the Gamma Doppler treatment—Phase 1 specifically—pouring deep jade, midnight teal, and hints of icy blue across the scimitar-curved blade in glossy, marblelike swirls. The skeletonized handles feature vivid neon-green inlays that echo the blade’s tones and pop during spin and inspect animations. As with all Dopplers, the pattern index shapes the flow of color: some P1 rolls lean darker and moodier, others show brighter pools of aqua, making every piece unique. In Factory New condition, the mirror finish is immaculate—no edge wear, scuffs, or dulling—so the gradient stays glassy from tip to tang. As a StatTrak™ skin, it includes a built-in digital kill counter on the weapon, tracking the number of enemies eliminated.
