★ Ursus Knife | Doppler Sapphire (Factory New)

The ★ Ursus Knife | Doppler Sapphire (Factory New) is a Covert ★ knife finish, a pure and deep translucent blue chrome with no black anywhere in it. At Factory New the blade sits at the very bottom of the finish's tight float range, where that blue reads at its most vivid.

Design

No secondary graphic here — Sapphire is one solid, deep translucent blue chrome, pure and free of any black mixed in. The flavor line "Getting lost in its color can prove fatal" ships with every copy of this phase, and honestly it fits.

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

Sapphire is capped between 0.00 and 0.08, so only Factory New and Minimal Wear exist for this phase — it never wears into a rougher look. Factory New occupies roughly 0.00–0.07 on the float scale, the lowest and cleanest band the finish reaches.

Ursus Knife | Doppler Sapphire Rarity

Rarity: Covert ★ — the gold-tier rare special ("knife") slot, standing above every regular Covert weapon skin a case might produce. That rarity comes from landing the knife slot itself, before wear ever factors in.

Ursus Knife | Doppler Sapphire Case and Collection

No single collection houses this phase — it comes out of the Prisma Case and the Prisma 2 Case. Both boxes share the same roughly 0.26% rare-special ("knife") pull rate, which is why most Sapphires change hands on the market rather than getting freshly unboxed.

Ursus Knife Doppler Phases

This knife's Doppler pattern spreads across several fixed phases, and this copy is locked into Sapphire permanently — the phase never shifts no matter how the blade wears. Within the full spread, the gem phases (Sapphire's blue, Ruby's red, and the iridescent Black Pearl) rank well above the numbered Phase 1 through 4 for both rarity and price; among the numbered set, Phase 2's pink and Phase 4's blue draw the most attention. Sapphire is one of that top trio.

StatTrak & Souvenir

A StatTrak™ version exists for this knife, permanently tracking confirmed kills through every trade or sale. Souvenir versions were never made, though — knives simply don't appear in Major-tournament souvenir packages, whatever the case or phase.

Ursus Knife | Doppler Sapphire Price

Factory New tops the Sapphire's own price ladder ahead of Minimal Wear, and the phase overall ranks among the priciest finishes this knife offers — a legitimate grail pick, not a middle-of-the-road Doppler. It's available to buy on Skin.Land with instant delivery and no hidden fees.

FAQ

What case is the Ursus Knife Doppler Sapphire in?

Sapphire drops from the Prisma Case and the Prisma 2 Case, not a single fixed collection. Since the rare-special ("knife") slot only lands around 0.26% of the time from either, buying on the market beats chasing the unbox for nearly everyone.

Which Doppler phase is best on the Ursus Knife?

The gem phases — Sapphire, Ruby, and Black Pearl — sit above the numbered Phase 1-4 in scarcity and price, and Sapphire's blue is one of those three. Among the numbered phases, the most saturated Phase 2 pink and Phase 4 blue are the ones buyers chase. The phase locks in at creation and never changes with wear.

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

Blue or navy gloves echo Sapphire's deep translucent chrome directly, while a black pair keeps the focus purely on the blade. Steer away from warm reds and oranges, which fight the cool tone rather than complement it. For the best Ursus Knife Doppler Sapphire glove combo, stick with blue or neutral black.
