This Flip Knife wears the Doppler treatment, built up from black and silver metallic paints swirled through a marbleizing medium and then sealed under a candy coat. Phase 4 leans into deep black with violet and pink streaks rather than the bluer phases, so collectors hunt specific blades for the exact pattern that lands on the back-swept Persian point.
