★ Survival Knife | Doppler Sapphire (Factory New)

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

Design

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

★ Survival Knife | Doppler Sapphire (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 blue coat at their most saturated. In float terms, this grade runs 0.00–0.07.

Survival Knife | Doppler Sapphire 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 Sapphire 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 Sapphire 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 Sapphire phase, prized for its solid blue 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 Sapphire Price

Factory New sits above Minimal Wear on the Sapphire'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 Sapphire in?

Sapphire 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 Sapphire the best Doppler phase?

Sapphire is one of the three gem phases, alongside Ruby 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 — Sapphire's solid blue look has its own dedicated following.

Does the Survival Knife Doppler Sapphire 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.
