Butterfly Knife | Doppler

★ Butterfly Knife | Doppler is a CS2 knife skin combining a pivoting butterfly blade with a marbled metallic finish. The pictured version contrasts dark purple and black with cloudy pink-violet accents. It suits players who prefer reflective color over a plain blade. Buyers can choose among Doppler phases, Factory New or Minimal Wear exteriors, and standard or StatTrak™ versions.

Description

★ Butterfly Knife | Doppler applies the Doppler finish to a CS2 butterfly knife, pairing metallic color with a distinctive folding design. Its freely pivoting blade opens in a fan-like motion, making the weapon's construction part of its visual character. The pictured blade carries irregular pink-violet marbling, while the dark handles have more structured detailing. This combination suits loadouts built around purple, charcoal, and reflective metallic accents. Available variants include Black Pearl, Phase 1, Phase 2, Phase 3, Phase 4, Ruby, and Sapphire. Exterior choices are limited to Factory New and Minimal Wear, keeping the condition selection focused. Standard and StatTrak versions are available, but there is no Souvenir version. Buyers should compare the phase, float value, exterior, and actual listing image rather than treating every Doppler copy as the same item.

History and Origin

★ Butterfly Knife | Doppler arrived on March 15, 2017, through the Spectrum Case Skins update. The Spectrum Case was its original release case, establishing case openings as an acquisition route. Valve created the finish rather than a community designer. The Spectrum 2 Case also contains this knife finish, providing another compatible case to open. Neither case drops as of October 9, 2026, following Valve's retirement of the rare drop pool on December 17, 2025. Existing cases can still be bought on the market and opened, so retirement did not remove the case-opening route. Opening either case remains chance-based, without a guaranteed result or a guaranteed Doppler phase. Today, direct alternatives include buying a listed copy on the Steam Community Market or arranging a trade with another player.

Finish Style

The Anodized Multicolored finish combines black and silver metallic paint with a marbling treatment beneath a candy-coated surface. On the pictured copy, the curved blade is predominantly black and deep purple. Cloudy pink-violet patches spread across the blade face, creating a mottled appearance rather than a uniform color block. A bright silver cutting edge separates that dark surface from the blade's outline. The handle arms use charcoal framing around elongated blue-purple inset panels. Reflective borders and silver pivot hardware give those darker handle sections contrasting highlights. Circular openings and short diagonal grooves add geometric detail without repeating the blade's cloudy pattern. Overall, the blade looks irregular and marbled, while the handles have a cleaner, more orderly arrangement.

Float Value

The float value ranges from 0.00 to 0.08, with Factory New and Minimal Wear as the available exteriors. The exterior label describes cosmetic condition, while the Doppler phase identifies the finish variant. StatTrak versions are available alongside standard copies, with version selection remaining separate from a copy's float and cosmetic condition.

Rarity and Popularity

★ Butterfly Knife | Doppler has Covert rarity, which is separate from its exterior condition and Doppler phase. Its drop chance from the Spectrum Case is 0.0085%, making that route uncertain for buyers seeking this specific knife. Professional players s1mple, Dosia, and donk own the skin, although their ownership does not establish market-wide demand.

Why it’s Popular:

• Metallic marbling with dark tones and pink-violet contrast

• Butterfly knife construction with a freely pivoting blade

• Distinct Doppler phases for different visual preferences

• Factory New, Minimal Wear, and StatTrak options

Price Range

The live ★ Butterfly Knife | Doppler price range is $1,773.35 to $9,650.93. These bounds cover the whole skin rather than a fixed phase or exterior. Phase, float, condition, and StatTrak status matter when comparing the CS2 skin price across individual listings. Ruby, Sapphire, Black Pearl, and the numbered phases should be checked as distinct variants rather than interchangeable purchases. Before buying or selling, compare matching versions and inspect their images instead of choosing solely by exterior label.

How to Obtain

1. Buy Directly through Eneba Skins

One of the fastest and most straightforward options is to purchase skins directly through Eneba Skins. You can browse available CS2 skins, compare prices, and choose the items that best fit your budget.

2. Open a Weapon Case

Open a Spectrum Case or Spectrum 2 Case for a chance at this knife finish. The Spectrum Case chance is 0.0085%, so opening one does not guarantee the skin or a particular phase. Neither case receives new drops, but existing cases can still be bought and opened.

3. Buy on the Steam Community Market

Buy a listed copy on the Steam Community Market to select a specific available variant instead of relying on a case opening. Check its phase, exterior, float, and StatTrak status before deciding whether the listing matches the intended purchase.

4. Trade with Other Players

Trade with another player to exchange existing items for a copy of this knife. Confirm the offered knife's phase, exterior, float, and StatTrak status before accepting, especially when comparing visually different Doppler variants.

Trading and Investment Considerations

Retired source cases limit fresh case supply, but existing cases can still be opened to introduce additional knives. Ownership by s1mple, Dosia, and donk provides visibility without proving how quickly any particular variant will sell. Buyers and sellers should compare matching phases and versions carefully, since the substantial purchase commitment makes uncertain demand an important consideration.

Reasons it Holds Value

• No new drops for either source case

• Distinctive metallic marbling and butterfly knife construction

• Multiple Doppler phases offer varied collecting choices

• Ownership by s1mple, Dosia, and donk

• Factory New, Minimal Wear, and StatTrak options

The investment outlook is medium-to-good, an editorial judgment supported by retired source cases, distinctive phase options, and professional ownership. The main risk is committing substantial value to a specific variant while existing cases can still produce knives and resale demand remains uncertain.
