★ Flip Knife | Doppler Ruby (Factory New)

The ★ Flip Knife | Doppler Ruby (Factory New) is a Covert ★ knife finish built from a pure, deep translucent red chrome with no black mixed in. Factory New covers the 0.00–0.07 band of the float scale, the cleanest grade available, and here that red chrome shows at its most saturated.

Design

Doppler Ruby skips any marbling or multicolor swirl entirely — it's a single, deep translucent red chrome coat with no black anywhere in the finish. It carries the flavor line "Getting lost in its color can prove fatal," which fits a phase this vivid.

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

Doppler Ruby 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 on any copy. At Factory New the blade sits at the very bottom of that range, giving the red chrome its sharpest, most mirror-like read. Factory New covers about 0.00–0.07 on the float scale.

Flip Knife | Doppler Ruby Rarity

Rarity: Covert ★ — this isn't an ordinary Covert skin but the gold-tier rare special, the "knife" slot that outranks every regular weapon grade drawn from the same case. Landing one at all is the hard part, well before wear enters the conversation.

Flip Knife | Doppler Ruby Case and Collection

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

Flip Knife | Doppler Ruby Doppler Phases

Doppler splits into several phases, and this is the Ruby gem phase. The gem phases — Ruby, Sapphire, and Black Pearl — sit well above the numbered Phase 1-4 finishes in rarity and price, with Ruby's pure red chrome among the most sought-after of the three. Which phase a copy lands as is fixed the moment it's generated and never shifts with wear, so a Factory New Ruby and a well-worn one are still the same phase.

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 Ruby Price

Factory New sits at the top of the Ruby 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 Ruby in?

It isn't locked to one box — Doppler Ruby drops from the Chroma Case, the Chroma 2 Case, and the Chroma 3 Case. That spread across three cases is a big reason most buyers just pick one up on the market instead of unboxing for it.

Which Doppler phase is best?

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

Does the Flip Knife Doppler Ruby 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.
