The Ursus Knife is a tanto-style full-tang blade, and this Doppler uses marbleized black and silver paints sealed under a candy coat. Phase 2 falls on the pink-leaning side of the Doppler range, a warmer tone that separates it from the bluer phases. The marbling means no two blades carry exactly the same swirl.

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.
