The Doppler finish floats black and silver metallic paints through a marbleizing medium, then seals them under a colored candy coat, so each M9 blade comes out with its own swirl of color and dark streaks. Different phases land on different hues, and the exact pattern that pools toward the tip is what separates one knife from the next.
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.
