The Doppler finish swirls black and silver metallic paints through a marbleizing medium before sealing the Flip's blade under a colored candy coat. Each blade pulls a one-off pattern from the marbling, and the specific phase determines the color you get. It is one of the most collected knife finishes precisely because no two come out the same.
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.
