★ Karambit | Doppler Phase 4 (Factory New)

The ★ Karambit | Doppler Phase 4 (Factory New, FN) is a Covert ★ knife finish, a mostly blue marbled finish laid over a black base. Factory New is as clean as this finish gets, and here that blue marbling shows at its most saturated. Most players just call it the karambit doppler phase 4 — or simply the karambit phase 4.

Design

Phase 4 leans heavily blue, with the color marbled thickly across a black base rather than appearing as an accent. It carries the flavor line "Getting lost in its color can prove fatal."

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

This phase is float-capped between 0.00 and 0.08, so only Factory New and Minimal Wear (MW) exist — a Doppler karambit never wears past a near-mint look. At Factory New the blade sits at the very bottom of that range, keeping the blue marbling at its most vivid. On the float scale, Factory New spans 0.00–0.07.

Karambit | Doppler Phase 4 Rarity

Rarity: Covert ★ — the gold-tier rare special, the "knife" slot that sits above every ordinary weapon grade in its case pool. Getting one at all is the scarce part, well before phase or wear factors in.

Karambit | Doppler Phase 4 Case and Collection

Doppler karambits come specifically from the Chroma line — the Chroma Case, Chroma 2 Case, and Chroma 3 Case. The rare-special ("knife") tier as a whole pulls at roughly 0.26% per case opening, so most buyers pick a specific phase up on the market instead of chasing it through unboxes.

Karambit Doppler Phases

Doppler splits into several distinct phases, and this copy is locked into Phase 4 for good — the phase never changes with wear once the skin is generated. The gem phases, Ruby, Sapphire, and Black Pearl, sit well above the numbered Phase 1-4 finishes in rarity and price. Among the numbered phases specifically, Phase 4's heavy blue marbling is one of the two most saturated looks buyers chase, alongside the pink Phase 2.

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.

Karambit | Doppler Phase 4 Price

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

FAQ

What case is the Karambit Doppler Phase 4 in?

It drops from the Chroma line of cases — the Chroma Case, Chroma 2 Case, and Chroma 3 Case. Because the rare-special tier only pulls around 0.26% per opening, and Phase 4 is just one of several possible phases, most buyers pick their phase up directly on the market instead of unboxing for it.

Is Phase 4 the best of the numbered Doppler phases?

Phase 4's heavy blue marbling is one of the two most saturated numbered looks, alongside the pink Phase 2, and both draw more buyer interest than Phase 1 or Phase 3. Even so, all four numbered phases sit below the gem phases (Ruby, Sapphire, Black Pearl) in overall rarity and price.

Does the Karambit Doppler Phase 4 have StatTrak?

Yes, a StatTrak™ version exists with a permanent confirmed-kill counter that follows the knife through trades and sales. There's no Souvenir version, though — knives are simply never part of Major-tournament souvenir packages, no matter the phase or case.
