Ruby is the prized end of the Flip Knife's Doppler line, where the marbleized base happens to cure into a deep, near-uniform red under the candy coat. That clean red is rare to pull from the marbling process, putting it well above the standard color phases. It is a Doppler finish collected purely for how much solid ruby the blade reveals.

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.
