About ★ Shadow Daggers | Doppler
The ★ Shadow Daggers | Doppler in Factory New brings CS2's most pattern-driven finish to its most affordable knife model. The Shadow Daggers — twin push-dagger blades from the Spectrum Case (March 2017) — sit at the bottom of the knife price ladder, which means Doppler on Shadow Daggers is the cheapest entry into Doppler-phase pattern hunting.
Phase rarity ladder
Doppler phases apply identically across all knife models. Ruby (deep red) and Sapphire (deep blue) are the apex phases — 4-8× generic Doppler price. Black Pearl (iridescent dark) sits below them. Phase 1, 2, 3, 4 command 1.5-3× generic depending on phase character. Generic non-phase Doppler is the price floor shown on this page.
FN as the phase-verification standard
FN preserves the chrome polish at maximum saturation, which is functionally required for phase verification. The transition between phase color and the chrome base is the visual diagnostic that confirms phase tier — and that transition only reads cleanly at FN.
