Doppler Phase 2 gives the balisong a blue-leaning candy finish over black-and-silver marbled metallic paint. Like the other phases the streaking is randomised, so flippers often pick copies for how the blue pools along the blade.
Butterfly Knife (Doppler Phase 2): 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.
