This Butterfly Knife carries the standard Doppler finish, marbling black and silver metallic paints under a candy coat to produce its glossy blue-to-black phases. Because the pattern varies, collectors single out specific blades for how the color lands across the balisong.
Butterfly Knife (Doppler): 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.
