This full-length M9 Bayonet carries a Doppler coat made the way every Doppler is, with metallic paints marbled together and sealed beneath a clear candy layer that deepens the color. Phase 4 is its own numbered slice of that pattern, tracked by collectors who watch the differences between the four standard phases. Because the marbling is never repeated, no two blades share an identical swirl.
M9 Bayonet (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.
