It’s not the Batarang, but it’s as close as you’re probably going to get

Of course Batman has a lot of cool gear and gadgets – he’s rich and has them custom made.  You may not have Batman’s resources, but you can have a knife that looks like Batman’s Batarang, which could  add some serious coolness to your Halloween costume this year.  The Batman 11.5″ Black Dual Blade Knife has two black-coated stainless steel blades.  The knife has a steel frame, and the handle covers are black aluminum.  The knife is 6″ closed and 11.5″ with both blades opened.  There’s a (utility) belt clip on the back, too.  The Batman 11.5″ Black Dual Blade Knife is $18.99 at Amazon.
