★ Flip Knife | Gamma Doppler Phase 4 (Factory New)

The ★ Flip Knife | Gamma Doppler Phase 4 (Factory New) is a Covert ★ knife finish, a deep green marbled coat laid over black. Factory New covers the 0.00–0.07 band of the float scale, the cleanest grade available, and here that green sits at its richest.

Design

Phase 4 keeps a black base but marbles it with a deep, saturated green, giving the blade more contrast than the lighter numbered phases while staying short of the grail Emerald's solid coverage. It's one of the darker, moodier looks in the Gamma Doppler lineup.

★ Flip Knife | Gamma Doppler Phase 4 (Factory New) Float and Wear

Gamma Doppler on this knife is float-capped between 0.00 and 0.08, so only Factory New and Minimal Wear ever exist — the finish never wears past a near-mint look no matter the copy. At Factory New the blade sits at the very bottom of that range, keeping the deep green marbling at its most defined. Factory New occupies the 0.00–0.07 float band.

Flip Knife | Gamma Doppler Phase 4 Rarity

Rarity: Covert ★ — this isn't an ordinary Covert skin but the gold-tier rare special, the "knife" slot that sits above every regular weapon grade pulled from a case. Landing one at all is the hard part, long before phase or wear enters the picture.

Flip Knife | Gamma Doppler Phase 4 Case and Collection

This finish isn't tied to a single collection — it drops from the Gamma Case and the Gamma 2 Case. The rare-special ("knife") tier as a whole lands at roughly 0.26% per case opening, which is why most buyers pick one up on the market instead of chasing that pull.

Flip Knife Gamma Doppler Phases

Gamma Doppler splits into five phases on this knife, and this copy's Phase 4 is fixed for good — it never shifts with wear or trades. Emerald is the grail phase, a solid green with no black, sitting far above the numbered Phase 1 through 4. Among those numbered phases, buyers favor the greenest, cleanest-looking copies, and Phase 4's deep green over black is one of the more sought-after picks in that group.

StatTrak & Souvenir

A StatTrak™ version of this knife exists and tracks confirmed kills permanently, carrying that count through any trade or sale. There's no Souvenir version at all — knives are never included in Major-tournament souvenir packages, regardless of case or phase.

FAQ

What case is the Flip Knife Gamma Doppler Phase 4 in?

It comes from the Gamma Case and the Gamma 2 Case, the two boxes that carry the Gamma Doppler finish on this knife. That's why most buyers pick theirs up on the market rather than opening cases hoping to land a specific phase.

Which Gamma Doppler phase is best on the Flip Knife?

Emerald is the grail — a solid, rich green with no black — and it commands a clear premium over every numbered phase. Among the numbered Phase 1 through 4, buyers gravitate toward the greenest, cleanest-looking copies, and this Phase 4's deep green over black is a recognized favorite in that group. The phase is fixed per copy and never changes with wear.

What are the best gloves for the Flip Knife | Gamma Doppler Phase 4?

Phase 4's deep green over black pairs naturally with gloves in dark green, olive, or plain black — anything that keeps the palette grounded rather than clashing with the contrast. For the best Flip Knife Gamma Doppler Phase 4 glove combo, stick with dark green or neutral black tones instead of brighter colors.
