★ Gut Knife | Doppler Ruby (Factory New)

The ★ Gut Knife | Doppler Ruby (Factory New, FN) is a Covert ★ knife finish carrying a pure, deep translucent red chrome with no black mixed in anywhere. Factory New covers the cleanest band of the float scale, and here that red chrome reads at its most saturated. Most players just call it the gut ruby — or the ruby gut, depending on who is typing.

Design

Doppler trades painted graphics for a marbled chrome coating baked straight onto the steel, and Ruby is one of three gem phases where that chrome settles as one solid color instead of a mixed pattern — a deep, pure red with none of the black marbling the numbered phases carry. It ships with the flavor line "Getting lost in its color can prove fatal."

★ Gut 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 (MW) exist for this finish — it never wears past a near-mint look no matter the copy. Factory New sits at the low end of that narrow range, the cleanest grade this finish comes in, covering roughly 0.00–0.07 on the float scale.

Gut Knife | Doppler Ruby Rarity

Rarity: Covert ★ — not a standard Covert skin but the gold-tier rare special, the "knife" slot that outranks every ordinary weapon grade pulled from a case. Landing one at all is the hard part, long before wear grade even enters the picture.

Gut Knife | Doppler Ruby Case and Collection

This finish isn't tied to a single collection — it comes from the Chroma line of cases, spanning the Chroma Case, Chroma 2 Case, and Chroma 3 Case. The rare-special ("knife") tier as a whole lands at roughly 0.26% per case opening, which is why most Ruby copies change hands on the market rather than getting pulled fresh.

Gut Knife | Doppler Phases

Doppler splits into several phases, and Ruby is one of the three gem phases alongside Sapphire and Black Pearl — together they sit well above the numbered Phase 1 through 4 in price. Among the numbered phases, buyers lean toward the most saturated ones, a vivid pink Phase 2 or a strong blue Phase 4, but Ruby's solid red chrome puts it in a bracket of its own. Whichever phase a copy lands on is fixed for good the moment it's generated and never shifts with wear.

StatTrak & Souvenir

This knife comes as a regular knife and a StatTrak™ version, which tracks confirmed kills permanently through any trade or sale. There's no Souvenir version at all — knives are never handed out in Major-tournament souvenir packages, regardless of finish or case.

Gut Knife | Doppler Ruby Price

Ruby sits in the grail-tier bracket among this knife's finishes — one of the priciest ways to own a Gut Knife, right alongside the other two gem phases. Factory New runs a bit ahead of Minimal Wear within that bracket, since it's the cleaner of the finish's two grades. It's available to buy on Skin.Land with instant delivery and no hidden fees. Prices for the ruby gut track the exterior, the float and whether the copy carries StatTrak™, so check the live number on this page.

FAQ

What case is the Gut Knife Doppler Ruby in?

It isn't locked to one box — Doppler drops from the Chroma line of cases, which covers the Chroma Case, Chroma 2 Case, and Chroma 3 Case. Since the odds are so thin either way, most buyers just pick up a Ruby copy on the market instead of chasing a specific case.

Does the Gut Knife Doppler Ruby have StatTrak?

Yes, a StatTrak™ version exists and adds a permanent confirmed-kill counter that carries through any trade or sale. There's no Souvenir version, though — knives simply never appear in Major-tournament souvenir packages, no matter the phase or case.

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

Ruby's solid red chrome pairs naturally with red or crimson gloves — anything with a deep red leather or a red-accented pattern keeps the loadout cohesive without fighting the blade's color. A plain black pair also works if you'd rather let the red chrome stand out on its own. For the best Gut Knife Doppler Ruby glove combo, lean into that red rather than mixing in cooler tones.
