★ Black Pearl is the rarest phase — some have sold for $50,000+. Only FN and MW exist (max float 0.08). Prices are approximate and vary by float and market. Use our inspect tool to identify the exact phase of any Karambit Doppler.
The ★ Karambit | Doppler was introduced with the Chroma Case on January 8, 2015, and remains one of the most sought-after knife finishes in CS2. Unlike most skins, the Doppler finish has a max float of 0.08— meaning only Factory New (0.00–0.07) and Minimal Wear (0.07–0.08) copies exist. No Field-Tested, Well-Worn, or Battle-Scarred Karambit Dopplers can exist. The Chroma 2 and Chroma 3 Cases also contain the Karambit Doppler, providing ongoing supply. The curved karambit blade showcases the Doppler finish's galaxy-like pattern particularly well, with the blade curvature creating dynamic color shifts during inspect animations.
Karambit Doppler comes in 7 phases, each determined by the pattern seed. The four standard phases — Phase 1 (pink/purple), Phase 2 (blue/pink, most popular), Phase 3 (blue), and Phase 4(purple/pink) — trade between $2,200 and $3,500. The three special phases occupy an entirely different tier: Ruby ($12,000–20,000) features solid red coverage, Sapphire ($15,000–25,000) features solid blue coverage, and Black Pearl($25,000–50,000+) is the rarest with its dark metallic appearance and subtle color shifts. Each special phase occurs with specific pattern seeds that produce nearly 100% single-color coverage. Use our inspect tool to identify the exact phase from any inspect link.
Both are premier Doppler knives, but they represent different price tiers and aesthetics. Butterfly Knife DopplerPhase 2 trades around $700–900 with Black Pearls reaching $8,000–15,000. Karambit DopplerPhase 2 trades at $2,700–3,500 with Black Pearls reaching $25,000–50,000+. The karambit's curved blade and unique inspect animation make it a favourite among collectors, while the butterfly knife's flip animation has its own dedicated following. For investors, both hold value well, but the Karambit's higher entry point and stronger prestige factor give it an edge in the high-end collector market.
