Stiletto Knife (Doppler Phase 4) (Factory New)

Covert Phase 4 StatTrak +0.7% · 8 d-5.5% · 28 d

This Doppler Phase 4 finish is produced by floating black and silver metallic paints on a marbleizing bath, then sealing the result under a candy coat, so the swirls fall differently on every Stiletto. Phase 4 specifically pulls toward the deep blue end of the Doppler range. The switchblade's instant spring deployment paired with a Covert marbled blade is the appeal.

Stiletto Knife (Doppler Phase 4): design, wear and market

Doppler phases

Doppler and Gamma Doppler are split into phases. Standard Doppler has Phase 1–4 plus the rare Ruby (red), Sapphire (blue) and Black Pearl. Gamma Doppler adds Emerald as its top phase.

The phase is part of the item and changes both the look and the value — Ruby, Sapphire, Emerald and Black Pearl trade well above the numbered phases. On this page the phase is shown in the name and selectable where variants exist.
