Managed to snag a very interesting (and likely very unofficial) prop on eBay a few months back. Made by a company called Phoenix Models it's a resin Batarang based on the one used at the end of the film - the one that Batman uses to destroy Nygma's Brain Sucking machine. Can't wait to get this painted and put together - I'll give another update when it's finished. The question is can I put a hinge in it so it slides together like it does in the film? Any advice in the comments below would be welcome.
