★ Ursus Knife | Doppler Ruby (Factory New)

The ★ Ursus Knife | Doppler Ruby (Factory New) is a Covert ★ knife finish built around a pure, deep translucent red chrome with no black mixed in. Factory New sits at the lowest-float end of the finish's narrow range, giving that red its most saturated, glassiest read.

Design

Doppler Ruby skips any secondary graphic — the whole blade is a single translucent red chrome, deep and pure with none of the black that shows up in the numbered phases. It carries the flavor line "Getting lost in its color can prove fatal," which fits a finish this striking.

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

This finish is float-capped between 0.00 and 0.08, so Factory New and Minimal Wear are the only two grades that exist — a Doppler Ruby never ages past a near-mint look. Factory New occupies the bottom of that band, roughly 0.00–0.07, the lowest-float and crispest the phase ever gets.

Ursus Knife | Doppler Ruby Rarity

Rarity: Covert ★ — this is the gold-tier rare special ("knife") slot, not an ordinary Covert weapon skin, and it sits above every regular grade a case can produce. Landing one at all is the hard part, well before wear enters the conversation.

Ursus Knife | Doppler Ruby Case and Collection

Doppler Ruby isn't tied to a single collection — it comes from the Prisma Case and the Prisma 2 Case. Across both, the rare-special ("knife") tier as a whole lands at roughly 0.26% per opening, which is why most buyers pick one up on the market rather than chase the pull.

Ursus Knife Doppler Phases

Doppler splits into several phases on this knife, and this copy is locked into Ruby for good — the phase is fixed the moment the skin is generated and never shifts with wear. Among the whole Doppler lineup, the three gem phases — Ruby's red, Sapphire's blue, and the iridescent Black Pearl — sit well above the numbered Phase 1 through Phase 4 in both scarcity and price; buyers chasing the numbered phases instead lean toward the more saturated Phase 2 pink or Phase 4 blue. Ruby is one of the two rarest, priciest results the Doppler pattern can roll.

StatTrak & Souvenir

A StatTrak™ version of this knife exists, adding a permanent confirmed-kill counter that carries 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.

Ursus Knife | Doppler Ruby Price

Factory New sits at the top of the Ruby's own price ladder, ahead of Minimal Wear, and lands among the priciest finishes this knife offers — a genuine grail-tier gem phase rather than a mid-pack pick. It's available to buy on Skin.Land with instant delivery and no hidden fees.

FAQ

What case is the Ursus Knife Doppler Ruby in?

It drops from the Prisma Case and the Prisma 2 Case rather than any single collection. Because the rare-special ("knife") tier only lands around 0.26% of the time from either box, most buyers get their Ruby on the market instead of chasing an unbox.

Which Doppler phase is best on the Ursus Knife?

The three gem phases — Ruby, Sapphire, and Black Pearl — outrank the numbered Phase 1-4 in both rarity and price, and Ruby's deep, pure red is one of those top three. Among the numbered phases, buyers favor the more saturated Phase 2 pink and Phase 4 blue. The phase is fixed per copy and never changes with wear.

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

Ruby's deep red chrome pairs naturally with red or crimson gloves for a matched loadout, or with black gloves if you want the blade's color to stand out on its own. Avoid cool blues or greens, which clash with the warm tone. For the best Ursus Knife Doppler Ruby glove combo, lean into red or go neutral black rather than fighting the hue.
