This Flip Knife carries the Gamma Doppler in its Phase 4 variant, where marbleized black and silver paints are candy-coated to bring out deep green swirls. Phase 4 is one of the darker, richer points in the Gamma range, set off against the knife's swept Persian-style blade. The marbling process makes every blade's pattern unique.
