★ Butterfly Knife | Doppler Ruby (Factory New)

The ★ Butterfly 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 is the sharpest-looking grade on offer, and here that red reads at its most saturated.

Design

Doppler Ruby skips any secondary color entirely — it's a single, deep translucent red chrome running the length of the blade, with none of the black marbling other phases carry. It ships with the flavor line "Getting lost in its color can prove fatal."

★ Butterfly 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 past a near-mint look no matter the copy. At Factory New the blade sits at the very bottom of that range, giving the sharpest, most even read on the red chrome. On the float scale, Factory New spans 0.00–0.07.

Butterfly Knife | Doppler Ruby Rarity

Rarity: Covert ★ — this sits above every ordinary weapon grade as the gold-tier rare special, the "knife" slot in its case. Landing one at all is the scarce outcome, before the phase itself even enters the picture.

Butterfly Knife | Doppler Ruby Case and Collection

This phase comes from the Spectrum Case and the Spectrum 2 Case. The rare-special ("knife") tier as a whole lands at roughly 0.26% per case opening, so most buyers pick a specific phase up on the market rather than chase it from a box.

Butterfly Knife Doppler Phases

Doppler splits into several phases, and this is Ruby. The two other gem phases, Sapphire (blue) and Black Pearl (iridescent), sit alongside Ruby as the rarest and priciest of the bunch, well above the numbered Phase 1-4; among those numbered phases, buyers lean toward the most saturated ones, Phase 2's pink and Phase 4's blue. Whichever phase a copy lands on is fixed the moment it's generated and never changes, wear or no wear — this copy is locked in as Ruby for good.

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.

FAQ

What case is the Butterfly Knife Doppler Ruby in?

It comes from the Spectrum Case and the Spectrum 2 Case. The rare-special ("knife") pull rate sits around 0.26% per case opening across the board, which is why most buyers grab a specific phase like Ruby on the market instead of gambling on a case for it.

Which Doppler phase is best on the Butterfly Knife?

The gem phases, Ruby, Sapphire, and Black Pearl, rank above the numbered Phase 1-4 in rarity and price. Among the numbered phases, the most saturated ones get picked most, Phase 2 for its pink and Phase 4 for its blue. Whichever phase a copy lands on is fixed for life and never shifts with wear.

What are the best gloves for the Butterfly Knife | Doppler Ruby?

That deep translucent red pairs naturally with red or maroon gloves, or a black leather pair that lets the blade's color carry the loadout. Steer clear of cool blues or greens, which clash with the warm tone. For the best Butterfly Knife Doppler Ruby glove combo, lean into red-toned or black leather gloves rather than fighting the phase's color.
