This straightforward model of mine is inspired by the bat weapon called baterang or batarang.
A batarang is a nearly bat-shaped throwing weapon. The name is a portmanteau of boomerang and bat, and was initially spelled baterang. Batarangs have become like shuriken in recent interpretations although they may be named after boomerangs. They've become a staple of Batman's arsenal, appearing in every big Batman television and movie adaptation to date. Recent interpretations of the Dark Knight locates added motivation to use the batarang as a ranged strike (option to firearms, which he rejects instantaneously because of the situation of his parents' murder) and is used mainly to knock guns out of an assailant's hand.
