★ Flip Knife | Doppler Sapphire (Factory New)

The ★ Flip Knife | Doppler Sapphire (Factory New) is a Covert ★ knife finish, a pure translucent blue chrome coat with no black anywhere in it. Factory New is the cleanest grade this finish comes in, and here that blue chrome comes through at its most saturated.

Design

Sapphire keeps things simple by design — a single deep, translucent blue chrome finish with no marbling or secondary color mixed in. It carries the flavor line "Getting lost in its color can prove fatal," a fitting nod to how striking the blue reads.

★ Flip Knife | Doppler Sapphire (Factory New) Float and Wear

Doppler Sapphire is float-capped between 0.00 and 0.08, so only Factory New and Minimal Wear exist for this phase — it never wears past a near-mint look regardless of copy. At Factory New the blade sits at the very bottom of that range, giving the blue chrome its sharpest, most mirror-like finish. Factory New occupies the 0.00–0.07 float band.

Flip Knife | Doppler Sapphire Rarity

Rarity: Covert ★ — this sits above an ordinary Covert skin as the gold-tier rare special, the "knife" slot that outranks every regular weapon grade pulled from the same case. Getting one at all is the hard part, long before wear comes into play.

Flip Knife | Doppler Sapphire Case and Collection

This phase isn't locked to a single collection — it comes from the Chroma Case, the Chroma 2 Case, and the Chroma 3 Case alike. The rare-special ("knife") tier as a whole lands around 0.26% per case opening, so most buyers pick theirs up on the market rather than chase that pull across three cases.

Flip Knife | Doppler Sapphire Doppler Phases

Doppler comes in several phases, and this copy has landed as Sapphire. The gem phases — Ruby, Sapphire, and Black Pearl — sit well above the numbered Phase 1-4 finishes in both rarity and price, with Sapphire's pure blue chrome a standout among the three. Which phase a copy becomes is fixed the moment it's generated and never changes as it wears.

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.

Flip Knife | Doppler Sapphire Price

Factory New sits at the top of the Sapphire phase's own price ladder, ahead of Minimal Wear, and lands in grail-tier territory among this knife's finishes overall — one of the priciest ways to own a Flip Knife. It's available to buy on Skin.Land with instant delivery and no hidden fees.

FAQ

What case is the Flip Knife Doppler Sapphire in?

It isn't tied to one box — Doppler Sapphire drops from the Chroma Case, the Chroma 2 Case, and the Chroma 3 Case. That spread across three cases is a big part of why most buyers pick one up on the market rather than unboxing for it.

Which Doppler phase is considered best?

The gem phases — Ruby, Sapphire, and Black Pearl — outrank the numbered Phase 1-4 finishes in both rarity and price, and Sapphire's solid blue chrome is one of the most desirable of the three. Among the numbered phases, buyers favor the most saturated ones, like the pink Phase 2 or the blue Phase 4.

Does the Flip Knife Doppler Sapphire 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 simply aren't part of Major-tournament souvenir packages, no matter the phase or case.
