★ Gut Knife | Doppler Phase 4 (Factory New)

The ★ Gut Knife | Doppler Phase 4 (Factory New) is a Covert ★ knife finish, a mostly blue marbled coat laid over a black base. Factory New covers the 0.00–0.07 band of the float scale, the cleanest grade available, and here that blue marbling reads at its sharpest.

Design

Phase 4 puts a mostly blue marbled pattern over black, and it carries the flavor line "Getting lost in its color can prove fatal." No decals or extra graphics — the swirl is the whole look.

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

Doppler is float-capped between 0.00 and 0.08, so only Factory New and Minimal Wear 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 crispest read on the blue marbling. Factory New covers about 0.00–0.07 on the float scale.

Gut Knife | Doppler Phase 4 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 | Doppler Phase 4 Case and Collection

This finish comes from the Chroma line of cases — the Chroma Case, Chroma 2 Case, and Chroma 3 Case all carry it. 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 Doppler Phases

Doppler splits into several phases, and this copy is locked to Phase 4. The gem phases — Ruby, Sapphire, and Black Pearl — sit well above the numbered phases in price, but among the numbered Phase 1-4 group, buyers lean toward the most saturated looks, and Phase 4's dense blue marbling is one of the two favorites (alongside Phase 2's pink). The phase is fixed the moment the skin is generated and never shifts 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 | Doppler Phase 4 Price

It's available to buy on Skin.Land with instant delivery and no hidden fees.

FAQ

What case is the Gut Knife Doppler Phase 4 in?

It drops from the Chroma line — the Chroma Case, Chroma 2 Case, and Chroma 3 Case all carry Doppler finishes. Because it spans three cases, most buyers grab a specific phase on the market rather than gambling on a fresh unbox.

Which Doppler phase is best on the Gut Knife?

The gem phases — Ruby, Sapphire, and Black Pearl — are the true grails and outprice the numbered Phase 1-4 group by a wide margin. Among the numbered phases, the most saturated looks get the nod, with Phase 4's dense blue marbling and Phase 2's bright pink the two most sought-after. The phase never changes once the skin is generated.

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

Phase 4's deep blue marbling pairs naturally with cool-toned gloves — navy, slate, or icy blue leather reads as a deliberate set rather than a mismatch. A black pair also works if you want the blade's marbling to stay the focal point. For the best Gut Knife Doppler Phase 4 glove combo, lean into those cool blues instead of clashing with a warm color.
