★ Gut Knife | Gamma Doppler Phase 1 (Factory New)

The ★ Gut Knife | Gamma Doppler Phase 1 (Factory New, FN) is a Covert ★ knife finish, a green-and-black marbled coat swirled across the blade. Factory New covers the 0.00–0.07 band of the float scale, the cleanest grade available, and here that marbling reads at its most vivid. Most players just call it the gut gamma doppler phase 1 — or simply the gut phase 1.

Design

Phase 1 pairs green with black in a marbled swirl, no two copies laid out quite the same. It's one of the four numbered phases in the Gamma Doppler line, sitting apart from the solid-color gem phases.

★ Gut Knife | Gamma Doppler Phase 1 (Factory New) Float and Wear

Gamma Doppler is float-capped between 0.00 and 0.08, so only Factory New and Minimal Wear (MW) ever exist — this finish never wears past a near-mint look no matter the copy. At Factory New the blade sits at the absolute low end of that range, giving the clearest read on the green-and-black marbling. Factory New covers about 0.00–0.07 on the float scale.

Gut Knife | Gamma Doppler Phase 1 Rarity

Rarity: Covert ★ — this isn't a standard Covert skin but the gold-tier rare special, the "knife" slot that sits above every ordinary weapon grade in a case. Pulling one at all is the rare outcome, long before wear even enters the picture.

Gut Knife | Gamma Doppler Phase 1 Case and Collection

This finish comes out of the Gamma Case and Gamma 2 Case rather than any single collection. The rare-special ("knife") tier as a whole lands at roughly 0.26% per case opening, so most buyers pick one up on the market rather than chase that pull.

Gut Knife Gamma Doppler Phases

Gamma Doppler spans five phases, and this copy is locked to Phase 1. Emerald is the grail of the set — a solid green with no black — and sits far above the numbered Phase 1-4 group in price; among those numbered phases, buyers favor the greenest, cleanest-looking copies. The phase is fixed per copy and never changes with wear.

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, full stop, regardless of case or collection.

Gut Knife | Gamma Doppler Phase 1 Price

Factory New sits at the top of this finish's own price ladder, ahead of Minimal Wear, and lands in the high-end bracket among this knife's finishes overall — a thin market keeps any single Gamma Doppler phase pricey. It's available to buy on Skin.Land with instant delivery and no hidden fees. Prices for the phase 1 gut track the exterior, the float and whether the copy carries StatTrak™, so check the live number on this page.

FAQ

What case is the Gut Knife Gamma Doppler Phase 1 in?

It drops from the Gamma Case and Gamma 2 Case. Landing a specific phase from a fresh case opening is a long shot on top of an already-rare knife pull, so most buyers just pick one up directly on the market.

Which Gamma Doppler phase is best on the Gut Knife?

Emerald is the grail — a solid green finish with no black — and it sells for far more than any of the numbered Phase 1-4 finishes. Among the numbered phases, the greenest, cleanest-looking copies tend to draw the most interest. The phase never changes once the skin is generated.

What are the best gloves for the Gut Knife | Gamma Doppler Phase 1?

Phase 1's green-and-black marbling pairs well with dark green or black gloves for a matched look, or a neutral gray pair if you want the blade's swirl to carry the loadout on its own. For the best Gut Knife Gamma Doppler Phase 1 glove combo, lean into greens and blacks rather than a bright, clashing color.
