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.

Float & wear: how it works
Float is a hidden 0–1 value generated when a skin drops. It sets how worn the skin looks and which exterior name it gets. A lower float looks cleaner and usually costs more, even within the same exterior.
This skin can roll float 0.00 to 0.08, so only the highlighted exteriors exist for it.
| Exterior | Float range |
|---|---|
| Factory New | 0.00 – 0.07 |
| Minimal Wear | 0.07 – 0.15 |
| Field-Tested | 0.15 – 0.38 |
| Well-Worn | 0.38 – 0.45 |
| Battle-Scarred | 0.45 – 1.00 |
This Flip Knife wears the Doppler treatment, built up from black and silver metallic paints swirled through a marbleizing medium and then sealed under a candy coat. Phase 4 leans into deep black with violet and pink streaks rather than the bluer phases, so collectors hunt specific blades for the exact pattern that lands on the back-swept Persian point.
