Batman is best known for his wonderful arsenal of gadgets and weapons, but even with a suit of bulletproof body armour the caped crusader probably still wouldn't touch this scary-looking knife with a ten-foot batpole.
Designed by Tom Anderson, the Interceptor looks like its creator started with a standard set of 'brass' knuckles but then went completely overboard with a series of fang-like blades. It's probably pretty effective at injuring an attacker, but from the looks of it, the person brandishing the blade might walk away with just as many cuts and abrasions.
And where the hell are you supposed to safely carry this thing? Note: Informational purposes only people. You'll very likely get in trouble if you tried to bring this into Australia. So don't.
