This is an instructable for making a replica of the batarang seen in the game “Batman: Arkham Asylum.” I wanted a batarang that unfolded with an action similar that that in the game. Not counting the cost of the tools, which I had already, and the paint (ditto), the entire project cost me about $17 and took perhaps 10 hours.
Step 1: Tools and Shopping List
I decided to make this prototype batarang out of Plexiglass, because a) it is easy to work b) it has no grain and doesn’t splinter or chip c) it is transparent, which helps with aligning the pieces d) it takes a metallic paint better than wood, and, finally, e) I didn’t have access to a metal-cutting bandsaw. Needless to say, you won’t be knocking any thugs unconscious with this one. You probably won’t be throwing it anywhere, either, unless you want to see your hard work shatter into bits.
