★ Survival Knife | Doppler Ruby (Factory New)

The ★ Survival Knife | Doppler Ruby (Factory New) is a Covert ★ knife finish, a pure translucent red chrome coat with no black mixed in. Factory New is the least-worn grade available, showing off that deep red at its most saturated.

Design

This is the Ruby phase of the Doppler line — a pure, deep translucent red chrome finish without the black marbling seen on other Doppler phases. The in-game flavor line sums it up well: "Getting lost in its color can prove fatal."

★ Survival Knife | Doppler Ruby (Factory New) Float and Wear

Doppler is float-capped between 0.00 and 0.08, so only Factory New and Minimal Wear ever exist for this phase — it never wears into a rough-looking copy. Factory New sits at the very bottom of that tight range, keeping the chrome surface and the red coat at their most saturated. In float terms, this grade runs 0.00–0.07.

Survival Knife | Doppler Ruby Rarity

Rarity: Covert ★ — the rare special ("knife") tier, a step above every ordinary weapon grade in a case rather than a standard Covert skin. Landing this knife at all is the scarce part, before phase or wear even factor in.

Survival Knife | Doppler Ruby Case and Collection

This phase drops from the Fever Case, the source that carries the Doppler line on this knife. The rare-special ("knife") tier as a whole lands at roughly 0.26% per case opening, so most Ruby copies are bought outright rather than pulled fresh.

Survival Knife Doppler Phases

Doppler splits into several phases, each fixed per copy and unaffected by wear. The gem phases — Ruby, Sapphire, and Black Pearl — sit well above the numbered Phase 1 through 4 in both rarity and price, and this is the Ruby phase, prized for its solid red color with no black. Among the numbered phases, buyers tend to favor the more saturated Phase 2 and Phase 4.

StatTrak & Souvenir

A StatTrak™ version of this knife exists, tracking confirmed kills with a counter that's permanent and carries over through trades and sales. There's no Souvenir version — knives are never included in Major-tournament souvenir packages, regardless of phase or case.

Survival Knife | Doppler Ruby Price

Factory New sits above Minimal Wear on the Ruby's own ladder, and as one of the gem phases it's grail-tier — among the priciest finishes this knife offers at all. It's a genuine showpiece pick rather than an everyday loadout item. It's available to buy on Skin.Land with instant delivery and no hidden fees.

FAQ

What case is the Survival Knife Doppler Ruby in?

Ruby drops from the Fever Case — the single source that carries this phase on the Survival Knife. There isn't another case to target, but the odds still sit at the rare-special tier's roughly 0.26% pull rate, so most buyers pick it up on the market instead.

Is Ruby the best Doppler phase?

Ruby is one of the three gem phases, alongside Sapphire and Black Pearl, and those three sit above the numbered Phase 1-4 finishes in both rarity and price. Which gem is "best" comes down to color preference — Ruby's pure red look has its own dedicated following.

Does the Survival Knife Doppler Ruby have StatTrak?

Yes, a StatTrak™ version exists with a permanent confirmed-kill counter that stays with the knife through any trade or sale. It doesn't come as a Souvenir, though — knives are never part of Major-tournament souvenir packages, no matter which phase or case.
