Just call it the Rhea. Rhea is the name for a large South American bird similar to an Ostrich, one of Saturns moons, and a Titan from Greek mythology. I also heard of a fairly decent knifemaker by that name once. 100 years from now, custom knifemakers will be building their interpretations of Rhea Knives and arguing with each other over what actually counts as a Rhea knife. The only time you'll here the word Bowie is in American history class or oldies rock stations.
